摘要
利用ANSYS有限元软件建立滑动摩擦副热-结构耦合模型,计算了模型的温度场以及热应力场,研究了模型在各种转速和载荷下的的温度变化,并通过试验验证计算模型的正确性。结果表明:建立的模型能够满足模拟滑动摩擦热分析要求;在滑动摩擦过程中,接触区最高温度在接触面中线并向外扩展,温度分布从接触面向四周呈递减趋势,而且温度梯度越来越小;接触表层最高温度与转速和载荷成线性关系。
A heat-structure coupling model of sliding friction pairs was established using ANSYS finite element software, and the temperature field and thermal stress field were calculated. The temperature change in a variety of speed and load of the model was studied, and an experiment was carried out to verify the correctness of the calculation model. The results show that the model can meet the requirements of thermal analysis of sliding friction. In the sliding friction process, the highest temperature is in the contact center line, the temperature distribution expands around in descending tendency, and temperature gradient is getting smaller and smaller. The highest surface temperature grows in direct proportion to the speed and load.
