摘　　要：通过介绍聚氨酯软木垫层材料压缩模量的试验方法,分析了压缩模量的特性及影响因素。分析结果表明:聚氨酯软木垫层材料压缩模量的特性近似于弹性材料的非线性曲线;试验方法、聚氨酯软木垫层材料的容重和粒度均对压缩模量有影响。The experiment method on compression modulus of polyurethane（PU） cork cushion material was introduced and the characteristic and influence factors of compression modulus were analyzed herein.The results show that the characteristic of compression modulus is similar to the nonlinear curve of elastic material,the experiment method and the bulk density and particle size of PU cork cushion material has an impact on the compression modulus.
