Finite element analysis of hard-coating composite structure considering strain-dependent characteristic

  • 摘要: 在简要介绍硬涂层材料应变依赖性的基础上,推导了用迭代有限元法求解硬涂层复合结构动力学特性的原理,进一步提出了求解硬涂层复合结构固有频率和振动响应的计算流程,即由振动响应值来修正硬涂层材料参数,进而迭代求解硬涂层复合结构的动力学参数.最后以一个涂敷MgO+Al2O3硬涂层的悬臂梁为例进行了实例研究,在考虑MgO+Al2O3硬涂层材料应变依赖性的基础上,获得了不同激励幅度下悬臂梁的固有频率和振动响应,并与线性计算结果进行了比对.结果表明;该硬涂层复合结构悬臂梁具有软式非线性,同时,对应于不同的激励幅度,迭代计算获得的共振响应相对于线性计算值减少了29%~48%,说明硬涂层材料的应变依赖性会进一步增强硬涂层的减振效果.
