机械弹性车轮静动态特性研究

摘要/Abstract

摘要：

为了揭示机械弹性车轮的性能特点，基于力学理论和虚拟样机技术对机械弹性车轮的静动态特性进行了研究。在静态工况下，对比分析机械弹性车轮完好状态下和有一根铰链组受损状态下的静力承载特性，结果表明，受损状态下承受最大拉力的铰链组与完好状态时有较大不同，不再位于輮轮顶部，且最大拉力值提高很多。在动态工况下，建立机械弹性车轮的驱动轮、从动轮和制动轮的力学模型，分析轮毂、铰链组和輮轮之间的力传递特性。最后在ADAMS中建立装配机械弹性车轮的整车模型并进行仿真研究，结果验证了机械弹性车轮的转动滞后角与输入转矩、车速和地面切向力之间的内在联系。

Abstract: In order to reveal the performance characteristics of mechanical elastic wheels, the static and dynamic characteristics of mechanical elastic wheels were studied based on mechanics theory and virtual prototype technology. The static loading characteristics of mechanical elastic wheels were analyzed comparatively under good conditions and with a hinged group damaged conditions. The results show that the maximum tensions of hinged group under damaged condition are quite different from those under intact condition. They are no longer located at the top of the wrestle wheel, and the maximum tension value is much higher than that under intact condition. The mechanics model of the driving wheel, driven wheel and brake wheel were established under dynamic conditions. Also, the wheel hub, hinged group and elastic wheel disk force transmissions were analyzed. Finally, the vehicle model with the elastic wheels was established in ADAMS and the simulation study was carried out. The results verify the natural relation among the rotational hysteresis angles of the mechanical elastic wheels and input torques, speeds and ground tangential forces.
