在温度场影响下,拖拉机离合器压盘在使用过程中常出现热烧蚀、热开裂等问题,大大降低了离合器总成的使用寿命。为解决上述问题,通过测绘φ280离合器压盘实物,在 SolidWorks 中,建立了完整的压盘实体模型,通过图形设备接口将其导入到了ABAQUS软件中,建立了有限元模型,经过热应力耦合分析计算得出压盘在滑磨过程中的受热及受力情况。同时,根据分析结果对压盘的结构进行了改进设计,得出了合理的压盘设计方案。结果表明:改进后的压盘轴向变形量降低了6.9%,应力峰值降低了11.96%。

Thermal ablation , thermal cracking and other problems often appear during the use of tractor clutch pressure plate , which greatly reduces the service life of the clutch assembly .To solve the problem above , complete platen solid model was established in Solidworks by mapping the φ280 clutch pressure plate .Then the finite element model is estab-lished by means of importing it into the software of ABAQUS using the ABAQUS and Solidworks interface .After thermal stress coupling analysis the heat and stress conditions of the pressure plate was calculated .According to the analysis re-sult ,the structure of the pressure plate is improved and the rational design was obtained .The results show that:the axi-al deformation of the improved pressure plate decreased 6.9% and it’s stress peak decreased 11.96%.
