摘　　要：从力学模型推导出空气弹簧与橡胶堆串联系统的垂向传递率,找出了橡胶堆自身阻尼特性对其整个系统阻尼特性的影响规律。从中得知传递率只与空气弹簧的容积比 n、频率比ξ及空气弹簧的阻尼比有关,与空气弹簧阻尼和橡胶阻尼之比 C 无关。对进一步分析、研究、开发新型结构空气弹簧有着指导性帮助和实用价值,特别是对垂向减振参数的选取、理论分析及设计计算有着现实意义。In this paper,the vertical transmissibility of the series system composed of air spring and rubber pile is de- rived with a mechanics model,and the law governing influence of damping characteristics of the rubber pile on damping characteristics of the complete system has been found out,From the transmissibility and the law derived,it is found that the transmissibility only relates to volume ratio of the air spring,the frequency ratio ξand the damping ratio of air spring,and is independent of the ratio C between air spring damping and rubber damping.This provides directive help and practical value in further analysis,research,and development of new structure air spring,especially it provides practical significance in selec- tion,theoretical analysis and design calculation of vertical damping parameters.
