Abstract :
In order to study vibration characteristic of the control cab, finite element model of the control cab was established, then vibration modal of control cab within 0-100Hz was analyzed. In order to verify the accuracy of the finite element model, the natural frequencies and mode shapes within 0-160Hz were tested. Test data was compared with simulation data, to prove that the established finite element model was correct. Reinforcing patch or damping patch could be pasted to avoid cavity acoustic resonance.
