摘要
采用欧拉梁和侧向分片的方法模拟轮胎侧向变形特性,利用二元傅里叶级数构造带束层单元的位移场,胎面横截面外轮廓设定为二次函数,建立了基于驱动力矩和侧倾力矩的轮胎三维接地性态解析计算模型。结合轮胎刷子模型计算了轮胎的纵向力和侧向力,并进行了验证。结果表明,模型具有较高的精度和效率。研究结果可为研究轮胎磨损和轮胎力学特性提供更为精确的三维接地压力分布解析模型,并为轮胎物理模型的解析研究提供新的思路和方法。
The lateral deformation was considered utilizing Euler beam and divided tire into slices in lateral direction.The displacements of belt elements were computed with two-variables Fourier series.The profile of tire cross-section was described as quadratic function.The model was verified by comparing longitudinal and lateral forces with tests.The results show that the model is more precision and efficiency.The methodology for building tire 3Dcontact model can be provided to explore the tire wear and mechanics behaviors.
