汽车通过性能试验方法(一)试验目的汽车通过性(越野性)是指汽车通过各种道路特别是坏路、无路地区及障碍物的能力。通过性是汽车主要使用性能之一,它不仅影响运输任务的完成,也影响其他性能的发挥。所以研究、改善和提高汽车的通过性,对国防及国民经济均有重要意义。汽车通过性主要取决于其几何参数和支承与牵引参数,同时汽车的其他性能、结构因素与使用因素对通过性也有很大影响。对汽车通过性至今缺乏系统的理论分析,特别是对汽车与相接触的道路和土壤等行驶介质之间的关系更缺乏研究。所以对通过性的评价参数很不完整,至今多采用比较试验方法。
Passenger vehicle performance test method (A) the purpose of the test Passing the car (off-road) refers to the car through a variety of roads, especially bad roads, road areas and obstacles ability. Passenger performance is one of the main performance of the car, which not only affects the completion of the transport mission, but also affect the performance of other performances. Therefore, studying, improving and improving the passing of cars will be of great significance to national defense and national economy. Passing through the car mainly depends on its geometric parameters and support and traction parameters, while other car performance, structural factors and the use of factors have a significant impact on the passage. So far, there has been no systematic theoretical analysis of the passing of vehicles, especially the lack of research on the relationship between vehicles and traveling media such as roads and soils in contact with each other. Therefore, the evaluation of the parameters through the sex is very incomplete, so far the use of comparative test methods.
