摘要
针对液力机械传动中液力变矩器发热量过大的问题,简述了液力变矩器的发热机理。在所构建的热计算模型的基础上,以某型推土机的液力变矩器为实例,运用MATLAB编程并得出了发动机与液力变矩器共同工作时发热量与传动比的关系曲线,并应用Simulink软件对不同传动比下的油温进行了仿真,仿真结果反映了油温的动态变化趋势。可为底盘油冷系统的分析和优化提供一定的技术参考。
According to the excessive heat of hydraulic mechanical transmission,heating mechanism on torque converter is explained.With a certain type of torque converter in bulldozers,the relationship between heat production and transmission ratio is described by Matlab programing,which on the basis of thermal analysis model.Meanwhile,the oil temperature on different ratio can be simulated by simulink,the result reflects the dynamic changing trend of hydraulic oil temperature.It will provide some technical reference for the analysis of chassis oil cooling system.
