本文在分清总行走阻力、外行走阻力和内行走阻力的基础上,以总行走阻力系数、外行走阻力系数和内行走阻力和系数为指标,评价行走机构性能。并介绍了用拖拉机与驱动法测定总行走阻力和内行走阻力的方法,对比了两种方法的测定结果。 Based on the analysis of the resistance of the head office, the resistance of external walking and the resistance of internal walking, this paper evaluates the performance of the running agency by taking the total resistance of walking, the resistance of walking outside and the resistance and coefficient of internal walking as indexes. The methods of measuring the total walking resistance and internal walking resistance by tractor and driving method are introduced. The results of the two methods are compared.
