【摘要】 建立了惯性通道式液力减振器的物理模型,推导出动刚度、滞后角和传递率的数学表达式,研究惯性通道局部截面积对液力减振器动态特性及系统力传递率的影响。仿真结果表明:优化局部截面积,可在较宽的频带内得到较好的隔振效果。更多还原

【Abstract】 A physical model of Hydraulic Mount with Inertia channel was set up. Its calculating formulate of dynamic stiff ness, typical damping and transmissbility was preseented. The paper studies the influence of channel’s partal cross-sectional area on dynamic characteristic of hydraulic mount and sysytem’s transmissbility. The emulating result indicates that optimal design of partal sectional area can reslut in the better effect of vibration isolation.更多还原
