摘  要:
用“下落”法测定轮胎的动刚度及阻尼系数值设备简单,方法方便可靠。当设备的主要构件刚性不足时,应将系统简化为一个三自由度有阻尼自由振动模型。利用此模型可以进行计算值的修正或指导测试设备的改造。

摘  要:
In this paper, "drop test" has been adopted to test tyres with its simple equipment requirement, easy manipulation and reliable tested result. For verifying the test precision, the compute simulation of the test system has" been conducted. It is proved that this test system can be simplified as a 3 degrce-of one freedom damped free vibration model which is used to rectify the mistake in calculation of dynamic parameters of tyres or to direct the improvement of test equipment.
