A Method for Testing Sealability of a Paint Body and Analysis of scheme

汽车气密性测试结果是衡量汽车车身NVH性能的重要指标之一。本文通过对某车型油漆车身气密性测试结果的分析,查明了油漆车身漏气的根本原因,找到了降低漏气的解决办法,通过改进气体泄漏量达到了设计目标的要求。

The test results of vehicle airtightness are one of the important indexes of NVtt. Through analysis the test results of the paint body, find out the root cause of the leakage, fbund the solution of reduce the leakage, reached the design target through improving the leakage amount.
