摘要: 轮胎力学特性受到多种复杂因素的影响,为了更加精确地表达机械弹性电动轮(Mechanical elastic electric wheel,MEEW)的力学特性,提出一种考虑热机耦合的MEEW力学模型。通过理论建模与试验验证相结合的方式开展研究,首先采用多功能摩擦磨损试验机进行多变量下的摩擦磨耗试验,对修正后的Savkoor摩擦模型进行拟合,分析温度、滑移速度、负载、路面条件等因素对MEEW胎面摩擦性能的影响;并对Lupker H磨耗模型进行修正与拟合,分析温度、滑移能量对MEEW胎面磨耗的影响。其次,通过分析温度、摩擦、磨耗等因素对力学模型的影响,修正了刷子模型。接着,使用轮胎综合力学特性试验台对所建立的模型进行了验证。最后,通过设计仿真工况,对比了刷子模型和考虑热机耦合的MEEW力学模型两种轮胎力学模型的表征效果。结果表明,所提出的考虑热机耦合的MEEW力学模型在准确表达MEEW力学性能的前提下,充分体现了温度、摩擦因数、滑移速度等因素的影响,验证了本研究的可行性与有效性。

Abstract: The mechanical properties of tires are influenced by various complex factors. To express the mechanical characteristics of the mechanical elastic electric wheel (MEEW) more accurately, a thermo-mechanical coupled MEEW mechanical model is proposed. This study combines theoretical modeling with experimental validation. First, a multifunctional friction and wear testing machine is used to conduct friction and wear tests under multiple variables. The revised Savkoor friction model is fitted to analyze the effects of temperature, slip velocity, load, and road conditions on the friction performance of the MEEW tread. The Lupker H wear model is modified and fitted to examine the impact of temperature and slip energy on tread wear. Next, the brush model is revised by analyzing the influences of temperature, friction, and wear on the mechanical model. The established model is then validated using comprehensive mechanical characteristics testing platform for tires. Finally, the brush model and the thermo-mechanical coupled MEEW mechanical model are compared in simulation conditions to evaluate their performance. The results demonstrate that the proposed thermo-mechanical coupled MEEW mechanical model accurately represents the mechanical performance of the MEEW while effectively capturing the impacts of temperature, friction coefficient, slip velocity, and other factors, confirming the feasibility and validity of this research.
