高速履带车辆履带销耳挂胶衬套拉压能耗研究

Research on tension and compression-energy consumption of track-pin ear hanger bushing for high-speed tracked vehicles

在高速履带车辆行驶过程中履带销与履带板之间有橡胶衬套的扭转和拉压变形导致的能量损耗,在履带车辆推进系统功能耗占比最大,而橡胶衬套受拉压变形导致的能量损耗研究甚少,因此需要对该部分能耗进行展开研究。针对履带销挂胶衬套的拉压滞后进行了理论建模分析,得出了拉压滞后能量损失的计算表达式;根据实验参数进行参数识别;最后通过比较得知不同频率下衬套的拉压能耗的数值解析结果与实验结果规律基本一致,且平均误差小于8%,所建立数值解析计算模型可满足工程应用的精度要求。

During the running of high-speed tracked vehicles, the energy loss caused by the twisting and tension-compression deformation of the rubber bush between the track pin and the track shoe is the largest among the crawler vehicle propulsion systems, while and the rubber bush is subjected to tension and compression deformation, the research on the energy loss caused by this part is very few, so we need to study the energy consumption of this part. According to the theoretical modeling analysis of the tension- compression hysteresis of the rubber pin of the track pin, the calculation formula of the energy loss of the tension-lag hysteresis is obtained. The parameters are identified according to the test parameters. Final- ly, the results of tension and compression energy consumption are basically consistent with the experi- mental results, and the average errors are less than 8%. The numerical analytical model can meet the precision requirements of engineering application.
