摘　　要：为了适应高速、高精度加工目标对龙门铣床横梁部件的要求,建立了横梁的实体模型,分析了其在实际工况下的静动态特性。通过对相关尺寸的灵敏度分析,找到了影响横梁整体性能的关键因素。给出了横梁的最大变形及低阶固有频率,并在此基础上进行了多目标优化。优化结果表明,采用此方法对提高横梁的性能有很大的帮助。In order to adapt to high speed and high precision machining target requirement for gantry milling machine beam, Entity model of beam is established, Analyzed static and dynamic characteristics under actu-al conditions. Through the sensitivity analysis of the relevant sizes, found the key factors influencing the beam overall performance. The biggest deformation and low order natural frequency of beam were given, the multi-objective optimization design was carried out on this basis. The optimum results showed that this method is of great help to improve the performance of the beam.
