Abstract
Aiming at the vibration test of the power train mounting system of certain light truck, a vibration test is performed, and vibration response at each testing point of the system is obtained in different conditions. Data is processed based on Matlab software, to display the time domain and the frequency domain response in an image way in each testing condition. The energy transfer efficiency of each mounting point, the vibration frequency domain response property, and the vibration intensities of the variable-speed joystick and the steering wheel in three directions are analyzed, a parameter design optimize proposal on the mounting system is proposed, and the vibration isolation effect can be improved by reasonably selecting parameters.
