关于某MPV车型整车气密性提升的优化设计

On a certain MPV models air-tightness enhance the optimization design for vehicle

整车气密性直接影响NVH、空调制冷制热等性能,是决定整车舒适度的重要因素。文章通过气密性试验测得某M车型的气密性相关参数,并通过优化结构及设计,最终实现整车气密性的提升。

Air-tightness directly affects the performance of NVH,air conditioning refrigeration system,and is an importantfactor to determine the comfort of the vehicle.In this paper,the air-leakage of M was measured by air-tightness test,and theair-tightness of the body was improved by optimizing the structure of the body.
