analysis professionals of the world typically leap into action. Taking data, analyzing that data and drilling down to the root cause of the problem. Without acceleration enveloping equipment owners will likely first become aware of damage to the bearing by seeing an increase in overall vibration, and in some cases a rise in temperature. At this point in the failure the damage is more likely to be extensive than if the bearing faults were identified earlier in the P-F curve. In the very worst case, collateral damage has likely already occurred and the equipment will have already experienced one, if not many different failure modes or even functional failure.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-top-column elementor-element elementor-element-dd1c734\" data-id=\"dd1c734\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-ebb5ff1 elementor-widget elementor-widget-image\" data-id=\"ebb5ff1\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"991\" height=\"747\" src=\"https:\/\/www.erbessd-instruments.com\/wp-content\/uploads\/2020\/09\/bearing-scortch.jpg\" class=\"attachment-large size-large wp-image-10086615\" alt=\"bearing fault anaylsis\" srcset=\"https:\/\/www.erbessd-instruments.com\/wp-content\/uploads\/2020\/09\/bearing-scortch.jpg 991w, https:\/\/www.erbessd-instruments.com\/wp-content\/uploads\/2020\/09\/bearing-scortch-300x226.jpg 300w, https:\/\/www.erbessd-instruments.com\/wp-content\/uploads\/2020\/09\/bearing-scortch-768x579.jpg 768w\" sizes=\"(max-width: 991px) 100vw, 991px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section data-particle_enable=\"false\" data-particle-mobile-disabled=\"false\" class=\"elementor-section elementor-top-section elementor-element elementor-element-4849e83 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"4849e83\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-top-column elementor-element elementor-element-c557062\" data-id=\"c557062\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-2db5fcb elementor-widget elementor-widget-text-editor\" data-id=\"2db5fcb\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<h2>How Acceleration Enveloping Works<\/h2><p>Acceleration enveloping is an incredibly powerful tool for vibration analysts and in many ways is superior to competing methods. Acceleration enveloping is a multi-step process that ERBESSD INSTRUMENTS and our award winning DigivibeMX software has automated to make bearing analysis easier. To understand how DigivibeMX handles this it is important to first understand the basics.<\/p><p>With acceleration enveloping, we should first apply a band pass filter to the mix of low and high frequencies of a defective bearing\u2019s unfiltered waveform. This will isolate only the bearing fault frequencies from within the signal that was collected. The filtered output generally identifies repeating high frequency data. This is often represented as a series of spiking energy bursts. These peaks are the impact of the rolling elements ringing down after coming into contact with the defect within the bearing.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-top-column elementor-element elementor-element-b4c6307\" data-id=\"b4c6307\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-2d1c0b6 elementor-widget elementor-widget-image\" data-id=\"2d1c0b6\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"600\" height=\"437\" src=\"https:\/\/www.erbessd-instruments.com\/wp-content\/uploads\/2020\/09\/vibration-analyzer-with-wireless-accelerometer.jpg\" class=\"attachment-large size-large wp-image-10086619\" alt=\"\" srcset=\"https:\/\/www.erbessd-instruments.com\/wp-content\/uploads\/2020\/09\/vibration-analyzer-with-wireless-accelerometer.jpg 600w, https:\/\/www.erbessd-instruments.com\/wp-content\/uploads\/2020\/09\/vibration-analyzer-with-wireless-accelerometer-300x219.jpg 300w\" sizes=\"(max-width: 600px) 100vw, 600px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section data-particle_enable=\"false\" data-particle-mobile-disabled=\"false\" class=\"elementor-section elementor-top-section elementor-element elementor-element-1102622 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"1102622\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-b5823a0\" data-id=\"b5823a0\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-41dc03c elementor-widget elementor-widget-image\" data-id=\"41dc03c\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"777\" height=\"205\" src=\"https:\/\/www.erbessd-instruments.com\/wp-content\/uploads\/2020\/09\/spiking.jpg\" class=\"attachment-large size-large wp-image-10086623\" alt=\"Acceleration Enveloping\" srcset=\"https:\/\/www.erbessd-instruments.com\/wp-content\/uploads\/2020\/09\/spiking.jpg 777w, https:\/\/www.erbessd-instruments.com\/wp-content\/uploads\/2020\/09\/spiking-300x79.jpg 300w, https:\/\/www.erbessd-instruments.com\/wp-content\/uploads\/2020\/09\/spiking-768x203.jpg 768w\" sizes=\"(max-width: 777px) 100vw, 777px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section data-particle_enable=\"false\" data-particle-mobile-disabled=\"false\" class=\"elementor-section elementor-top-section elementor-element elementor-element-df63448 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"df63448\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-0f2c562\" data-id=\"0f2c562\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-b04ce6c elementor-widget elementor-widget-text-editor\" data-id=\"b04ce6c\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>Next, we must pass the filtered output through an enveloping algorithm which then rectifies (demodulates) the waveform by inverting the negative part to the positive to create more density and then extracts the repetition rate of the energy spikes. This new enveloped signal helps the fault frequencies present and stand out from all other energy. The envelope assists in containing regularly spaced energy spikes such as an inner race or outer race defect. Acceleration enveloping is a great tool for synchronous energy analysis as the envelope helps contain and identify the regularly spaced synchronous peaks.<\/p><p>DigivibeMX\u2019s band pass filter range is 10x the RPM value specified in the machine point definition. This is why an RPM value must be specified when setting up the machine points. If the RPM is 0 or no RPM was specified, the band pass filter would be 0-10,000 CPM.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section data-particle_enable=\"false\" data-particle-mobile-disabled=\"false\" class=\"elementor-section elementor-top-section elementor-element elementor-element-cff0c6e elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"cff0c6e\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-top-column elementor-element elementor-element-87c481f\" data-id=\"87c481f\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-0b9da5b elementor-widget elementor-widget-text-editor\" data-id=\"0b9da5b\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<ul><li>DigivibeMX first removes low frequencies below 10x RPM with an FFT<\/li><li>Next, the FFT is inverted<\/li><li>Then, DigivibeMX converts all values from negative to positive, maximizing density<\/li><li>Next, the envelope is applied by joining all the top points of the curve<\/li><li>Lastly, we calculate the resulting FFT for analysis<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-top-column elementor-element elementor-element-55f40e3\" data-id=\"55f40e3\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-b794f1d elementor-widget elementor-widget-image\" data-id=\"b794f1d\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"698\" height=\"400\" src=\"https:\/\/www.erbessd-instruments.com\/wp-content\/uploads\/2020\/09\/P-4-1.jpg\" class=\"attachment-large size-large wp-image-10086630\" alt=\"Fault Analysis\" srcset=\"https:\/\/www.erbessd-instruments.com\/wp-content\/uploads\/2020\/09\/P-4-1.jpg 698w, https:\/\/www.erbessd-instruments.com\/wp-content\/uploads\/2020\/09\/P-4-1-300x172.jpg 300w\" sizes=\"(max-width: 698px) 100vw, 698px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section data-particle_enable=\"false\" data-particle-mobile-disabled=\"false\" class=\"elementor-section elementor-top-section elementor-element elementor-element-dd4200c elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"dd4200c\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-2e34f84\" data-id=\"2e34f84\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-940f36c elementor-widget elementor-widget-text-editor\" data-id=\"940f36c\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<div class=\"wpb_text_column wpb_content_element \"><div class=\"wpb_wrapper\"><h2>Key Considerations<\/h2><\/div><\/div><div class=\"wpb_text_column wpb_content_element \"><div class=\"wpb_wrapper\"><p>It is critical to understand that as with all vibration analysis some skill and experience are needed to interpret the data.
