摘要
为了解湿式双离合器摩擦副工作表面热状况,通过建立双离合器起步过程动力学模型,利用MATLAB/Simulink软件对接合时摩擦副滑摩功进行了仿真计算。分析了不同接合条件对滑摩热量的影响,研究了接合时主从动件转速差、接合油压、滑摩时间以及钢片厚度对钢片整体温度的影响。仿真结果表明,接合时滑摩时间对钢片整体温度影响最大,转速差影响次之,油液压力影响相对较小。增加钢片厚度可以增大其热容量,降低最高温度。
In order to comprehend the thermal condition on working surface of friction pairs of wet dual clutch,the dynamic model of dual clutch in starting process is established.And the slipping work of the friction pairs at the engagement is simulated and calculated by software MATLAB/Simulink.The influence of different bonding conditions on the sliding friction heat is analyzed.The effects of revolution of master and slave parts,oil pressure,sliding time and thickness of steel on the overall temperature of steel sheet are studied.The simulation results show that the sliding time has the greatest influence on the overall temperature of the steel sheet,the influence of revolution difference is secondary,and the influence of oil pressure is relatively small.Increasing thickness of the steel sheet can enlarge its thermal capacity and reduce the maximum temperature.
