Dynamic Design by Modification of Cabin for Decreasing Vibration

This paper used test modal analysis method to identify parameters of cabin of diesel automobiles. It was found that the tenth natural frequency of the cabin is near to the frequency of the second inertial force of engine. This causes great vibration of cabin. Dynamic modification design can avoid the response of the tenth natural frequency of cabin with the second inertial force of engine. The result shows that the vibration is decreased obviously.
