I am trying to analyse response of a dynamic system. The source disturbance is about x,y,theta (rotation about x ) & Phi of one coordinate system (red coloured coordinate system in the attached figure). I need to get the response in another coordinate system ( green coloured coordinate system...

Thanks for your response. The sides of the panel is approximately 800 mm. During testing accelerometer was put at 4 locations on the panel. In my FE model, I gave the same input force as that in testing and checked the response at the location of accelerometer, (exact location was not known, so...

ok, I have experimental data upto 120 Hz only, in which only first mode is captured. I will try to model the complete structure. Thanks for the reply

Sir, the complete cuboid is ~ 1000 kg, whereas top panel assembly is only ~62 kg. The systems mounted on top deck are highly stiff (frequency >1Khz). So my idea is to make FE model of only top deck (instead of complete structure) for analysis, but this top deck model must have same dynamic...

I have an assembly (a cuboid shaped structure). The vibration test data of this structure is available with me. I want to study the effect of vibration generated by a system mounted on top panel on another system mounted on same top panel. In order to complete this, I have prepared the FE model...

Hello , I am Chinmay Rajhans, pursuing my M.tech in Aerospace Engg. My area of interest in Vibration isolation and structural dynamics

I have developed a mathematical model to study the dynamic behavior of rotor (with 6 dof). It is assumed that rotor is rigidly mounted at the mid point of shaft, and both end of the shaft is attached to ball bearing. I have developed the FE model for it too, and the frequencies in X, Y, Theta...
