正交实验与多元线性回归方法在开式压力机机身优化设计中的应用

Application of the Orthogonal Experiment and Multivariate Linear Regression Method in the Optimum Design of the Open-type Press Frame

基于有限元软件模拟分析压力机在实际工作状况下的受力情况,利用正交实验与多元线性回归方法对影响压力机机身的结构因素进行分析,建立最优化数学模型,对其求解,得到优化结果。

Based on the finite element software, the open-type presses is simulated in actual work stress condition. The influence of the structural factors on the press frame is analyzed by orthogonal experiment and multivariate linear regression method. The mathematieal model is estahlished and solved, its optimization results are obtained.
