【摘要】 对金属橡胶隔振器的冲击性能进行了理论和实验研究。借助于金属橡胶构件的加载曲线和迟滞回线,研究了具有非线性干摩擦阻尼隔冲系统在短冲击和长冲击时的最大响应的计算方法,并借助于M atlab实现了最大冲击响应的逐步积分计算。通过实验研究了构件结构形状和参数、负载质量、冲击加速度等对金属橡胶构件抗冲击性能的影响,对理论方法进行了验证,为工程实践提供了依据。更多还原

【Abstract】 The shock protection characteristics of a metal rubber isolator were studied theoretically and experimentally.Based on primary loading curve and hysteresis loop of isolators,the calculation method for maximum response of a nonlinear shock protection system with dry friction damping to short and long shock impulses was proposed.The stepping integration of the maximum response was programmed using Matlab software.The effects of structural parameters,loading,and shock acceleration level on the shock protection performance of metal rubber isolators were studied experimentally to testify the theoretical calculation method.The results are beneficial to engineering application of metal rubber isolators.更多还原
