摘　　要： 在Archard模型的基础上构建了一种考虑摩擦副接触面积的磨损量计算模型。依据实验结果确定了磨损系数K的函数表达式,讨论了单一工况条件下不同接触比例摩擦片对离合器磨损量的影响规律。基于搭建的湿式离合器磨损量测试试验台,对4种不同接触比例的摩擦片进行了滑摩试验,得到了磨损前后摩擦片磨损量结果,验证了数学模型的准确性和有效性。试验结果表明,应用该磨损量计算模型可以有效预测不同接触比例摩擦片的磨损量,有助于湿式离合器寿命评估和减磨耐磨设计。 The effect of contact area on wear performance of wet clutch is investigated in this paper. Based on the experimental results,the expression of wear coefficient is confirmed,and the influence of contact area on wear performance of friction disc is discussed with single load. In addition,the 80 minute sliding test with four different contact area of friction discs are carried out on the wet clutch test rig. Compared with the measured values,the accuracy of the calculation models is verified. The test results show that the calculated and detected data fit well,which indicates that the wear calculating model can be used for estimating the wear mass loss of wet clutch friction plate. The research results showed in this paper will help improve the anti-abrasion properties and employment life span of wet clutch friction disc.
