Analysis and Research on Static Test Methods of Elastic Modules of Biomechanical Equivalent Artificial Soft Materials

针对生物力学等效软质材料的特点,在对现有测试方法研究分析的基础上,提出一种适于软质材料的基于光栅尺和千分表的弹性模量测试方法,实现了软质材料等应变下的压缩测试,并设计了测量所需的微位移系统。通过对测试结果的分析,验证了上述方法的可行性。

This paper is based on the research and analysis of the existing related measuring methods, and aimed at the characteristics of equivalent artificial soft materials, and it also proposes a new adaptable test method to measure elastic modules. The modules are based on capacitive gate transducer and micrometer which suits for soft materials. Based on this proposed method, a micro feed mechanism has been designed. The same strain of soft materials under compress test was realized, and the feasibility of this method by analyzing the test results was testified.
