摘要
从轮胎结构设计角度出发,通过改善轮胎接地特性,降低滚动轮胎与路面接触过程中胎体的振动,提升轮胎的噪声性能。首先,采用任意拉格朗日ALE方法对轮胎进行稳态滚动分析,获取路面激励引起的轮胎瞬时动态响应,在此基础上,采用边界元方法预测了不同结构轮胎滚动时的振动辐射噪声。然后,考虑轮胎接地压力对胎面振动的影响,对接地压力分布与轮胎噪声性能间的关系进行了深入分析。结果表明,建立的新非自然平衡轮廓胎体结构可以改善轮胎与路面接触过程中的相互作用,使得接地面内压力分布更均匀,实现了轮胎振动辐射噪声性能的提升,振动辐射噪声较现行设计轮胎减小了3.7dB。
This research aims at improving tire vibration noise by reducing tire vibration behavior in tire/road contact period through tire contour design.Firstly,the tire steady state rolling process is simulated by ALE method and the corresponding tire transient dynamic response is achieved.Considering the effect of tire contact pressure on tire vibration,the relationship between tire contact pressure and tire vibration noise is analyzed.The result shows that,the new non-natural equilibrium tire contour design will improve the tire road contact process and achieve a more evener tire contact pressure distribution,which improveds the tire noise level as far as 3.7dB reduction relative to the original structure design.This research will provide a guideline for low noise tire structure design and effectively improve the tire vibration noise.
