摘要
为了研究速差转向过程中的轮胎工作状态,提出了一种基于二维载荷分布规律的轮胎侧偏特性的一般理论模型.根据此模型对速差转向车辆的轮胎工作状态进行分析,推导侧向力及回正力矩表达式,提出了起滑曲线的概念,并给出了相应的简化方法.分析表明,在考虑轮胎横向载荷非均匀分布的情况下,轮胎侧偏特性与以往的横向平均载荷分布模型存在较大差别.
To investigate the tire working state during skid-steering,a general theoretical model of tire cornering properties based on two-dimensional load distribution was established.The working state of the skid-steering tire was analyzed and the expressions of lateral force and aligning torque were derived.Moreover,the slip curve was presented and the simplified method was proposed.The result shows that,compared with the condition of uniform load,the condition of non-uniform load leads to a great difference in tire cornering properties.
