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。

Abstract: 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.

Key words: adhesive layer, stand-off layer damping structure, vibration characteristics, modal strain energy method, control variable method
