重型柴油车“三高”试验

"Three high"Test of Heavy Duty Diesel Vehicle

“三高”试验是考验整车能否适应极端环境的重要依据,是整车开发和验证中的重要环节。本文介绍了高寒、高温、高原环境对重型柴油车性能的影响与“三高”试验项目,最后对环境模拟试验技术进行了简介。这对重型柴油车生产企业开展整车“三高”试验与建立科学有效的“三高”试验规范具有一定参考意义。

"Three high"test is an important basis to test whether the vehicle can adapt to extreme environment,and it is an important link in vehicle development and verification.This paper introduces the influence of cold,high temperature and plateau environment on the performance of heavy-duty diesel vehicles and the"three high"test items,and finally introduces the environmental simulation test technology.It has certain reference significance for heavy-duty diesel vehicle manufacturers to carry out vehicle"three high"test and establish scientific and effective"three high"test specification.
