摘要
用动力学原理建立了两自由度双轴汽车的数学模型 ,详细分析了汽车前后悬架固有频率的匹配关系。对某车型前后悬架固有频率的匹配进行了讨论 ,并作了改进设计。试验研究表明 ,理论分析与实际是吻合的 。
Two free dual-shaft vehicle′s mathematic model is set up by using kinetic principle,and the matching relationship of inherent frequency between vehicle′s fore suspension and rear suspension is analysed in detail .Combinedwith certain strickling ,discussion is possessed .And improved design is done for it. Research of experiment proves that analysis of theory concides with the fact well,and the purpose of improving ride comfort is achieved.
