摘　　要：针对工程机械和轨道交通中的振动隔离问题,以橡胶弹簧隔振系统为研究对象,采用理论推导、仿真分析和试验验证相结合的方法,研究了橡胶弹簧的隔振特性及其影响因素.建立了橡胶弹簧的本构方程,提出了橡胶弹簧隔振特性的理论计算方法,进行了橡胶材料的力学特性试验,并结合橡胶弹簧隔振系统的有限元模型,通过仿真分析得出如下结论:橡胶弹簧的隔振特性随激励频率、隔振系统质量、橡胶弹簧刚度和阻尼的变化而变化,且其绝对传递率随橡胶弹簧刚度和阻尼的增加而增大,随隔振系统质量的增大而减少,当激励频率小于28.3rad/s时,绝对传递率随激励频率的增加而增大,当激励频率为28.3rad/s时,绝对传递率达到最大值,当激励频率大于28.3rad/s时,绝对传递率随激励频率的增大而减少.According to the vibration isolation problem of Engineering machinery and rail transit,with rubber spring vibration isolation system as the research object,it used the method of theoretical derivation,simulation analysis and experimental validation of a combination of factors,to study the vibration isolation characteristics of rubber spring and its influencing factors.Established the constitutive equation of rubber spring rubber material based on the constitutive model,put forward the theoretical calculation method of rubber spring vibration isolation characteristics,tested the mechanical properties of rubber material,and combined with the finite element model of rubber spring vibration isolation system.It can draw the following conclusions through simulation analysis method：the vibration characteristics of rubber spring changes with excitation frequency,quality of vibration isolation system,rubber spring stiffness and damping,and its absolute transfer rate increases with stiffness and damping,and reduces with the quality of isolation system.The absolute transfer rate increases with the increase of excitation frequency when the excitation frequency is less than 28.3 rad/s,reaches the maximum value when the excitation frequency is 28.3 rad/s,and decreases with the increase of excitation frequency when the excitation frequency is greater than 28.3 rad/s.
