摘要
为解决接触力学中温度对于微凸体弹塑性接触特性所产生的影响,本文考虑温度的影响,对可变形球体与刚性平面的单微凸体接触模型进行研究。通过有限元分析,研究温度对于接触深度、接触力与接触面积的影响,并将结果与经典模型进行对比。在相同的接触深度下,接触力、接触面积与温度几乎成正比关系,表明温度对于各个参数具有较大影响,并通过曲线拟合得到不同接触深度下接触力、接触面积与温度的经验表达式,为后续的研究奠定理论基础。
The elastic-plastic contact problem between a deformable sphere and a rigid plane is a major problem in contact mechanics.This paper introduces a single asperity model considering the influence of temperature.Using finite element analysis,the influence of temperature on contact depth,contact force,and contact area was investigated,and the results were compared with classical models.The results indicate that,at the same contact depth,contact force,contact area,and temperature are almost directly proportional,revealing temperature′s significant impact on various parameters.Empirical expressions for contact force,contact area,and temperature at different contact depths were obtained through curve fitting,providing a theoretical foundation for subsequent research.
