Mtbf Calculation

In recent times, mtbf calculation has become increasingly relevant in various contexts. Phase Angle Calculation | AMP Maintenance Forums. Hi All; I wish to discuss about phase angle calculation from time waveform. Recently I wading through a vib analysis software, In time waveform information display Phase related particulars were also displayed, But I'm sure that the data was collected... Multiple speed correction calculation Required | AMP Maintenance Forums.

Dear forum members, I am working in Shop balancing ( Highspeed balancing tunnel, Schenck) I am balancing the rotors by using static / couple method. (Pedestal vibrations) only which is very much useful This correction reduces the all vibrations below the operating speed and at the operating speed also. and some times using single plane correction also depending upon the requirement.

Defect length determination in antifriction bearings!! Building on this, hi guys, I just need some help in the calculation of defect length in an antifriction bearing!!

I got some equations for calculating the defect length from Taylor's Vibration Handbook. But some explanation part was lost due to some damage in the... Bently panel accel output | AMP Maintenance Forums. A quick calculation indicates that at 10 Hz and 5 g's peak you would have to have something just short of an inch pk-pk of displacement.

The choice of course is yours but I generally like including the lower end; it rarely has ever given a problem but has on occasion detected a bad transducer. viscosity conversion at different temperatures | AMP Maintenance Forums. This seems like the type of calculation that should be available in an on-line calculator somewhere, but I couldn't find it anywhere. Moreover, so I created the attached spreadsheet that will determine viscosity as a function of temperature based on known viscosity at two temperatures (such as 40C and 100C).

residual unbalance in soft bearing balancer/IRD?. in the end, what i want to ask is this, how i measured the quality of low speed balancing using soft bearing machine if my guideline is API 687 - rotor repair, residual unabalance? my theory of residual unbalance calculation using IRD.

Vibration Analysis Certification Exam Category I Data Acquisition .... On the calculation side, based on my experiments (using the equations), most of the reasonable configurations will require DAT between 0.1-5 seconds. Additionally, i used a variety of resolution lines, frequency spans, averaging and overlap.
