| 摘 要： | 针对过大的摩擦因数变化率可能引发离合器控制失效的问题，提出了一种基于摩擦因数变化率的可靠性补偿控制方案.利用SAE#2试验台，在不同输入转速、油温、油压下，完成了摩擦副摩擦因数试验，获得了摩擦因数随工作参数的变化规律.基于摩擦因数变化率建立了失效评价模型，并设计了补偿模糊控制方案.台架试验结果表明，在摩擦因数变化率较大的高温重载工况下，改进后的控制算法有效延长了离合器接合时间，提高了离合器摩擦副的工作可靠性.

| Abstract: | A reliability compensation control scheme was proposed based on the change rate of friction coefficient to solve the problem of possible clutch control failure caused by an excessive change rate of friction coefficient. By using SAE#2 test platform, the friction coefficient test was completed, and the variation of friction coefficient with working parameters was obtained under different input speed, oil temperature and oil pressure. A failure evaluation model was established based on the change rate of friction coefficient and the compensation fuzzy control scheme was designed. The bench test results show that the improved control algorithm can effectively extend the clutch engagement time and improve the working reliability of the clutch friction pair under the high temperature overload condition with high friction coefficient. |
