摘要
本文在粘弹性材料静态力学试验的基础上研究材料的粘弹性本构关系,提出了应用■义力学系统来分析材料力学性能的方法,推导了复域、时域和频域的粘弹性本构方程,■由频域粘弹性本构方程入手分析了粘弹性材料的阻尼损耗能。最后介绍了用于测试粘弹性材料动态特性的系统识别法及设计的微机测试系统。
The constitutive relations of viscoelastic material are investigated based on static test. The method with generalized system is advanced to analyze the mechanical proper ties of materials. The viscoelastic constitutive equations in complex-rcgion, time-re gion and frequency-region are inferred. With the frequency regional constitutive equation the loss-damping energy is caculated. Finally a microcomputer mcasurement system for investigating the dynamic characteristics is described.
