采用偏最小二乘回归方法,经交叉有效性检验建立了接合正压力的平均值、接合转速、滑摩时间与摩擦片表面最高温度的关系模型,模型对各种因变量的累计解释能力超过90%,通过该模型计算得到的拟合值与实际值的平均相对误差为3.90%,优于最小二乘支持向量机的预测效果,为AMT离合器开发、控制设计的优化及实现过温保护提供了依据.
The partial least squares regression method was used to establish the model of the relationship between the average positive pressure, the engagement speed and the maximum temperature of friction surface through the cross validity test. The cumulative explanatory power of the model for various dependent variables exceeded 90 %, And the average relative error between the fitted value and the actual value calculated by the model is 3.90%, which is better than that of the least square support vector machine. It provides the optimization of AMT clutch design and control design and the over-temperature protection in accordance with.
