摘　　要：针对电动振动台垂直扩展台面一阶垂向共振频率较低的问题,以某垂直扩展台面为研究对象,采用有限元软件建立垂直扩展台面的有限元模型,以空心圆柱内圆半径、裙边高度、裙边至台面中心距离和台面底部安装半径作为优化参数,通过不同的试验设计分别构造响应面拟合的输入矩阵和验证矩阵,最后采用全局响应面法对垂直扩展台面的结构参数进行优化。结果表明,优化后的垂直扩展台面一阶垂向共振频率由2132.98Hz提升至2185.21Hz,从而验证了该优化方法的有效性。该方法对其他台面的优化设计具有一定的参考意义。Aiming at the problem that the first order vertical resonance frequency of the vertical expansion table of electric vibration table is low,this paper takes a vertical expansion table as the research object,and uses the finite element software to establish the finite element model of the vertical expansion table.The radius of the inner circle of the hollow cylinder,the height of the skirt,the distance from the skirt to the center of the table and the installation radius at the bottom of the table are taken as the optimization parameters.The input matrix and the verification matrix of the response surface fitting are constructed through different experimental designs.Finally,the structural parameters of the vertical expansion table are optimized by using the global response surface method.The results show that the first order vertical resonance frequency of the optimized vertical expansion table is increased from 2132.98Hz to 2185.21Hz,which verifies the effectiveness of the optimization method.The method has certain reference significance for the optimization design of other mesas.
