    Decoding ARINC 717

    I have an ARINC 717 file in binary format. I know the Syncwords, there are Teledyne format. I have all the parameter addresses both analog and binary. I am using Matlab to open the binary file by specifying that its a 12 bit word. The sync words for each subframe are 4018 words apart, it should...

    Vibration Monitoring of CNC Machinery

    I am looking for information on Vibration Based Condition Monitoring of CNC machines. What are the most common maintenance issues with CNC machines and which of those can be detected using vibration?

    Noise from Discharge Side of Centrifugal Pump

    I am trying to create a demo centrifugal pump to show increased vibration from cavitation. I have a pump running at 2900 RPM and a 2 inch suction side pipe and 2 inch discharge pipe with a increaser. The pump is a Kirloskar DB 32/13 End Suction Pump. I can get cavitation by closing the suction...

    Shaker Setup

    I am trying to test a beam (132 lbs weight) under free boundary conditions using an electrodynamic shaker (rated 110lbf sine). I connected the shaker, which is attached to two cinder blocks, to the beam using a long nylon stinger and a force transducer. The problem I have is that when I input a...

    Opinion on Course on Electrodynamic Shakers

    I have done some testing using electrodynamic shakers, mostly sine dwell testing but I want to learn advanced stuff with shakers (Random vibration, multiple shaker testing etc). I wanted your opinion about the Fundamentals of Electrodynamic Vibration Test Systems course offered by ITES...

    UFF 58

    I am trying to create a UFF 58 format file for FRF's. Does the data that goes in the UFF 58 have to be in Mag/Phase format or Real/Imag. format?

    Place to rent Impact Hammer

    Hi, I have to test something next week and I called Modalshop for renting at short sledge impact hammer and they are out. Is there any other place that I can rent a 5lb impact hammer?

    FRF from FE Model

    I have a FE model for a deck, I obtained the displacement response at location B due to a unit sinusoidal load over a frequency range at any input location A. Can this response I obtained be called as a Frequency Response Function?

    How to get FRF from a Ansys Model

    I have modelled a deck in Ansys. I was able get the frequncies and mode shapes, but I want to get the frequency response functions for the deck. How do I do that?

    Calculating Frequency Response Function in Ansys

    I have modeled a composite deck and extracted the frequencies and mode shapes. I wanted to know how to get the frequency response functions, so that I can correlate them to the experimental ones?

    Calculating response from FRF

    I have different FRFs for a 3DOF system. I want to calculate the response at 3rd DOF due to a sinusoidal input at the 2nd DOF. How do go about doing the calculation?

    Simply Supported Steel I-Beam Test

    I am trying to test a steel I-Beam on simple supports, I've done a swept sine test using a shaker and accelerometer and calculated (Half-power method)the damping ratio to be 2.1%. I think is too high a number for an steel beam, my guess is it should be less than 1/2%. My question is could my...
