摘要
结合同步器实际结构和工作条件,运用AMESim、Matlab以及Abaqus软件建立同步器换挡动力学模型、摩擦副摩擦接触机理模型以及有限元分析模型,采用热结构耦合法对同步器同步过程中的温度特性进行仿真研究。从同步器力学响应出发,结合同步器摩擦接触机理与热分析理论,对同步器同步阶段摩擦接触区域的热学特性进行建模、仿真与分析,结论表明模型最高温度位置处于在整个摩擦区域中间部位,同步锁环摩擦衬片摩擦面的最高温度为106.0℃,啮合齿圈摩擦锥面的最高温度为78.3℃。通过对同步器摩擦接触面温度场的分析为后续对其摩擦接触面热失效形式与机理的分析奠定了基础。
Combined with the actual structure and working conditions of the synchronizer,AMESim,MATLAB and ABAQUS software are used to establish the gear shifting dynamics model,friction contact mechanism model and finite element analysis model of the synchronizer.The thermal structure coupling method is used to simulate the temperature characteristics of synchronizer during synchronization.Based on the mechanical result of the synchronizer and the friction contact mechanism and thermal analysis theory of the synchronizer,the thermal characteristics of the frictional contact area during the synchronization phase of the synchronizer are modeled,simulated and analyzed.The results show that the maximum temperature of the model is in the middle of the whole friction area,the maximum temperature of the friction surface of the synchronous lock ring is 106.0℃,and the maximum temperature of the friction cone surface of the meshing ring is 78.3℃.The analysis of the temperature field of the synchronizer lays a foundation for the subsequent analysis of the thermal failure form and mechanism of the friction contact surface.
