【摘要】 汽车发动机悬置系统动力设计程序，张建润，王志新（东南大学机械工程系，南京２１００１８）对汽车发动机悬置系统解耦优化设计已能较好地控制发动机振动传给车架，但是，作了两点简化：视车架为刚体、未考虑路面的激励。本研究应用模态综合理论对整辆汽车作振动分析，建...更多还原

【Abstract】 Twenty freedoms model system is used to indicate the automobile including engine mount-ing system,On the basic of it,we establish physical modal of engine mounting system and use the ma-trix pernlrbation method to compute frenquencies and modal shape of it.by the require of vibration iso-lating of itself and frenquency matching of whole vehicle’s each structure,this papor puts forward anoptimization modal which regards the accleration of seats as the object function.更多还原
