摘　　要：建立了车体-构架双质量系统的垂向及横向振动测试模型。以齐次旋转矩阵理论为基础搭建了激振平台位姿反解模型,并对各激振器控制指令进行计算。对某型转向架悬挂实现垂向振型自振频率测试,试验结果与理论值一致,验证了本文方法的准确性。In this paper the vertical and lateral test models of vehicle body-frame double mass system were established. The inverse displaeement 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.
