为研究履带车辆在砂土路的行驶特性,分析计算其直线行驶时的履带牵引力与滑转率的关系,根据履带车辆地面接地压力分布试验测试结果,建立了接地压力简化模型,提出了一种履带车辆地面牵引力的计算方法。结合土壤参数试验测试结果,计算得到履带车辆每个负重轮下地面牵引力以及整车的地面牵引力与滑转率的关系,并进行了地面牵引力实车试验,测试结果和计算结果的一致性验证了计算模型的可信性,为履带车辆行驶载荷的计算奠定了基础。
In order to study the running characteristics of tracked vehicles on sandy soil road, the relationship between crawler traction and slip rate was analyzed and calculated. According to the test results of tracked ground pressure distribution test, a simplified model of ground pressure was established and a crawler Calculation Method of Vehicle Ground Traction. Based on the test results of soil parameters, the relationship between traction force of ground under each wheel and the traction force of the whole vehicle and the slip ratio was calculated. The actual traction test of the ground was carried out. The consistency between the test results and the calculated results verified The credibility of the model is calculated, which lays the foundation for calculating the running load of tracked vehicles.
