摘要
考虑胶层在自由型垫高阻尼结构中传递应力、应变的作用,将胶层等效为各向同性材料,采用ANSYS和MATLAB的联合仿真方法,分析含胶层的自由型垫高阻尼结构振动特性随胶层参数的变化规律。利用模态应变能法和控制变量法得到的结果表明,胶层对结构振动特性起着关键性的作用,因此,选择胶粘剂敷设自由型垫高阻尼结构时,应在保证胶层力学环境良好的前提下,选择满足胶层最佳特性区间的胶粘剂产品。
Considering the effect of adhesive layer on the stress and strain in unconstrained stand-off layer damping structure,adhesive layer is equivalent to the isotropic material.The joint simulation method of ANSYS and MATLAB is used to analyze the vibration characteristics of unconstrained stand-off layer damping structure with adhesive layer with adhesive layer parameters.The results obtained by modal strain energy method and control variable method show that the adhesive layer plays a key role in the structural vibration characteristics.Therefore,the choice of adhesive laying unconstrained stand-off layer damping structure should ensure that adhesive layer has good mechanical environment under the premise of choice to meet the best properties of adhesive layer of adhesive products.
