摘　　要：通过对随机激励下干摩擦隔振系统理论的深入研究,推导了金属橡胶隔振系统随机激励均方加速度响应求解公式.对金属橡胶隔振器进行随机振动试验,分析了金属橡胶隔振器相对密度、预变形及所加试验量级对金属橡胶隔振系统均方根加速度响应的影响,得到了相关变化规律曲线.同时还分析了均方根加速度响应理论值与试验值的对比误差,确定了公式的适用范围.Based on the theoretical study of the dry friction isolation system under the random vibration,a formula for the description of the acceleration response of metal rubber （MR） isolation system under random vibration was derived. An experimental research for the MR isolator subject to random vibration excitation was carried out,and the effects of the relative density,the preliminary deformation,and the acceleration level of excitation on the root mean square of acceleration response for the isolation system were analyzed and depicted in curves. The theoretical root mean square of acceleration response was compared with the experimental ones,and the range for the practical use was determined.
