摘要
为了研究湿式多片离合器摩擦副的发热情况,选取其中一对摩擦副,建立了瞬态及稳态热分析有限元模型,将油槽类型转化为当量圆柱体并建立对流换热模型,计算了对流换热系数,并以此为边界条件,计算不同时间下摩擦片与对偶钢片沿径向和轴向的温度分布。同时,针对不同材料及槽型对摩擦副温度的影响进行分析,并采用SAE#2试验机,测试了不同材料及槽型的摩擦副温度,与理论分析进行了对比,温度变化趋势一致,误差较小。
In order to study the temperature characteristics of the friction pair in the wet clutch friction pair,the transient and steady-state thermal analysis finite element model for a pair of friction pairs is established,in which the oil groove type is transformed into an equivalent cylinder.The convective heat transfer model is established.The convective heat transfer coefficient is calculated.The radial and axial temperature distributions of the friction plate and the steel plate under different times are calculated.At the same time,the influence of the different materials and geometries on the temperature of the friction pair are analyzed,the SAE#2 machine was used to test the temperature of the friction pair of different materials and groove types,and the test results have little error.
