摘　　要：用现有的拉伸-应变实验方法测量软质生物仿真材料的弹性模量是非常困难的。提出了一种利用生物仿真材料硬度测试系统和千分表相结合、对软质材料采用压缩-应变的实验方法,并对实验数据进行了曲线拟合。试验结果表明,这种方法能够实现软组织仿真材料弹性模量的测量,有助于对活体组织生物力学等效性的比较和判别。It is difficult to test the elastic modulus of the soft bio-anthropomorphic materials by using the general stretch-straln test method. With the equipment for a hardness testing system of bio-anthropomorphic materials and millesimal gauge,we introduce in this paper a compress-strain test method and carry out the related test-data curve-fitness. The test results indicate that this kind of method can be adopted in testing the elastic modulus of the soft bio-anthropomorpbic materials and help to compare and distinguish the biomechanics equivalent between the tissues.
