Abstract: In this paper the vertical and lateral test models of vehicle body-frame double mass system were established. The inverse displacement analysis model of the excitation platform was put forward, which was based on the theory of homogeneous rotation matrix. The control command for the vibration exciter was solved via the inverse displacement analysis model. Meanwhile, a vehicle test for vertical natural frequency was conducted. The test result was consistent with theoretical value, which proved the accuracy of the test method.

Key words: vehicle engineering, bogie, simulation of semi-vehicle, natural frequency, inverse displacement analysis
