摘　　要：建立了微孔橡胶垫板结构简化模型,对动静比与能量损耗的关系进行了定性分析,并考察了测试频率和加载力值对动刚度和动静比的影响。结果表明,在外力作用下,橡胶垫板的内耗越大,则动刚度和动静比越大;随着测试频率和加载力值的增加,动刚度和动静比均增大。A terse structure model of microcellular rubber pad was established. The relationship between insertion loss and the ratio of dynamic stiffness and static stiffness（SD/SJ）was analyzed. The effects of measure frequency and load on the dynamic stiffness and the ratio of SD/SJ were studied. The results showed that the bigger the insertion loss of microcellular rubber pad, the bigger the dynamic stiffness and the ratio of SD/SJ. With increasing measure frequency and load, both dynamic stiffness and the ratio of SD/SJ increased.
