针对离合器摩擦片数量的增加可以显著提高离合器传递扭矩的能力和接合过程的效率，而过多的摩擦片可能导致接合时间增长、系统复杂度增加及影响动态稳定性的问题，为提升离合器接合过程的稳定性，根据动力学原理建立采棉机变速箱湿式离合器模型，对湿式离合器摩擦扭矩、滑摩功、冲击度的接合特性进行仿真与分析，然后选用摩擦扭矩、接合时间、滑摩功、冲击度为评价指标，对比分析当离合器摩擦片数量分别为3、4、5时各指标的变化特性，并对仿真数据进行对数归一化处理，再利用熵权法确定以上指标的权重分别为24.1%、26.2%、24.9%、24.8%,并计算不同摩擦片数量的综合得分。结果表明：摩擦片数量为5时，综合得分最高为0.76;适当的摩擦片数量可提高接合效率、传递扭矩的能力，减缓冲击。研究结果可为采棉机变速箱离合器接合特性分析及离合器摩擦片的数量选择提供参考。
Abstract：Increasing the number of clutch friction plates can significantly enhance the clutch′s torque transmission capability and the efficiency of the engagement process, however, an excessive number of friction plates may lead to longer engagement times, increased system complexity, and issues affecting dynamic stability. To improve the stability of the clutch engagement process, a wet clutch model for a cotton picker transmission was established based on dynamics principles, and the engagement characteristics of the wet clutch′s friction torque, slip work and impact were simulated and analyzed. Then, using friction torque, engagement time, slip work, and impact as evaluation metrics, the variations of these indicators were compared and analyzed for 3, 4, and 5 clutch friction plates. And the simulation data were normalized logarithmically, and the entropy weight method was used to determine the weights of these indicators as 24.1%, 26.2%, 24.9% and 24.8%, respectively, and a comprehensive score was calculated for different numbers of friction plates. The results show that when there are 5 friction plates, the comprehensive score is highest at 0.76. An appropriate number of friction plates can improve engagement efficiency, torque transmission capability, and reduce impact. This study provides a reference for analyzing clutch engagement characteristics and selecting the number of clutch friction plates in a cotton picker transmission.
