橡胶弹簧隔振特性及其影响因素研究
Research of Rubber Spring Vibration Isolation Characteristics and Its Influence Factors
摘要
Abstract
According to the vibration isolation problem of Engineering machinery and rail transit,with rubber spring vibration isolation system as the research obj ect,it used the method of theoretical deriva-tion,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 rub-ber spring changes with excitation frequency,quality of vibration isolation system,rubber spring stiff-ness 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 fre-quency when the excitation frequency is less than 28.3 rad/s,reaches the maximum value when the exci-tation frequency is 28.3 rad/s,and decreases with the increase of excitation frequency when the excita-tion frequency is greater than 28.3 rad/s.关键词
