商用车道路可靠性试验探析

The Reliability of Commercial Vehicle Road Tests

本文论述了汽车道路可靠性试验开展的意义及重要性;依据试验开展的具体工作对可靠性组织进行了确定;明确了设计、试制及质量部门向可靠性试验组织输入的必要文件及实物;从试验里程确定、试验内容及试验条件等方面阐述了汽车试验场道路可靠性大纲的编制方法;最后从三种不同路面(高速环道、强化路及场内山路)试验方法、故障反馈处理及闭环、可靠性数据统计及可靠性试验报告等方面详尽阐述了试验场道路可靠性试验开展的具体内容及方法,为汽车试验场道路可靠性试验开展提供一定的参考。

The meaning and importance of the reliability of vehicle road tests are discussed. The reliable organization is confirmed, based on the specific work carried out in the tests. The necessary documents and objects provided by the design, trial production and quality departments are decided. The methods to compile an outline for the road conditions on the vehicle test ground are specified from the perspectives of test mileage, test contents and test conditions. Last, the specific contents and methods of conducting the vehicle road tests on the test ground are expounded in such aspects as the three different road conditions which are high-speed ring road, asphalt road and mountain road, failure feedback processing and closed loop, reliability statistics and reliability test report, which attempts to provide reference for vehicle road tests on the test ground.
