摘　　要：为了探究并改善某型龙门铣床横梁结构在承受最大载荷时的静动态性能,利用有限元方法对龙门铣床横梁结构进行了静动态性能分析,并进行了铣床横梁筋板结构的尺寸优化。采用正交试验方法确定初始变量值,采用中心复合设计和Kriging插值法构建响应面模型,通过多目标遗传算法对横梁筋板布局和尺寸进行了优化设计。优化结果表明,采用质量最轻方案,质量减幅可达1.98%;采用最大总变形量最小方案,最大总变形量减幅可达2.13%。研究结果可为实现铣床横梁筋板结构尺寸最优配置提供仿真参考。In order to explore and improve the static and dynamic performance of the crossbeam structure of a gantry milling machine under the maximum load,the finite element method was used to achieve the static and dynamic analysis and also the size optimization of the stiffened plates structure in the crossbeam.The orthogonal experiment design method was used to determine the initial variable values.The response surface models were constructed based on the Central Composite Design(CCD)method and Kriging interpolation method.The Multi-Objective Genetic Algorithm(MOGA)was used to find the optimal solutions of the design positions and sizes of the stiffened plates of the crossbeam.The optimized results show that when compared with original crossbeam,with a scheme of the optimal mass,the mass of the optimized crossbeam can be reduced by 1.98%;with a scheme of the optimal total deformation,the maximal total deformation can be reduced by 2.13%.The results can provide the simulation reference for achieving the optimal configuration dimensions of the stiffened plates in the crossbeam.
