摘　　要：迟缓打滑是弹性车轮最常见的失效形式,针对这种失效形式,设计了一种采用机械抗打滑结构的弹性车轮。根据运用工况,对弹性车轮进行了仿真分析,证明其强度和疲劳寿命满足技术要求;通过对抗打滑性能测试,采用抗打滑结构的弹性车轮比普通的弹性车轮具有明显的优势;通过模拟不同温度环境下的抗打滑性能测试,证明采用抗打滑结构的弹性车轮在不同温度下皆具有优良的抗打滑性能。对弹性车轮的模态和振动频响进行分析和测试,结果表明弹性车轮具有较高的模态阻尼比,对高频振动和辐射噪声有很好的抑制作用。Slip is the most common failure form of elastic wheel.Aiming at this technical problem,an elastic wheel with mechanical anti-slip structure was specially designed.According to the operating conditions,the elastic wheel was simulated and analyzed,and it was proved that its strength and fatigue life met the technical requirements;through the anti-slip comparative test,the elastic wheel with anti-slip structure had obvious advantages over ordinary elastic wheels.By simulating the anti-skidding performance test under different temperature environments,it was proved that the elastic wheel with this structure had excellent anti slip performance at different temperatures.The modal and vibration frequency response of elastic wheel were analyzed and tested.The results showed that elastic wheel had high modal damping ratio and could restrain high-frequency vibration and radiated noise.
