【摘要】 为了研究双板间的连接形式对振动特性的影响,采用模态叠加法同时结合板间的耦合条件,对双板系统的振动控制方程进行处理,分别推导了含弹簧连接、含夹层流域及二者同时存在情况的理论公式,得到了系统的振动响应。由于对中间含流域的有限大双板的理论推导极为繁琐,本文采用适当的简化,得到了比较理想的效果,在与有限元结果的对比中吻合较好。在此基础上进一步研究了弹簧刚度、水层厚度等参数的变化对双板振动特性的影响。更多还原

【Abstract】 In order to study the influence of the connection form between the two plates on the vibration characteristics,the modal superposition method was adopted to deal with the vibration governing equations of the two-plate system by combining the coupling condition between the plates,and the theoretical formulas for the spring connection,the basin with interlayer fluid and the coexistence of the two were derived respectively,and the vibration response of the system was obtained.Because the theoretical derivation of finite large double plate with intermediate basin is very complicated,this paper adopts appropriate simplification,and gets a relatively ideal effect,which is in good agreement with the finite element results.On this basis,the influence of spring stiffness,water layer thickness and other parameters on the vibration characteristics of the double plate is further studied.更多还原
