提出基于响应面法的横梁结构优化方法，对液压机上横梁立板的厚度进行优化设计。通过单因素实验系统地考察各筋板厚度对上横梁挠度的影响量，并进行方差分析、模型拟合度分析，再利用响应面优化法，以挠度最小为优化目标，优化设计各筋板厚度，所得最优立板厚度分别为65.96,mm、87.29,mm、54.41,mm、37.74,mm，最优挠度为0.615,79,mm，较原始设计方案提升了12.39%,。与有限元模拟值比较，得出响应面拟合模型的结果准确性高，也证明优化方法的可行性。

Based on response surface method,the thickness of THP29-6300,hydraulic auto carling beam was opti-mized.Through a single factor experiment,the influence of stiffened plates’ thickness on beam deflection was systemati-cally studied.Then,analysis of variance and the fit of model analysis were carried out.TheBox-Behnken Design-response surface optimization method was used to find the minimum deflection as an optimization goal.The optimal steel plate thick-nesses were 65.96,mm,87.29,mm,54.41,mm and 37.74,mm respectively.The optimal deflection was 0.615,79,mm,a 12.39%, promotion than the original scheme.Compared with the finite element simulation value,it is concluded that the response surface model fitting results are of high accuracy and good feasibility.
