摘　　要：机床静刚度是评价机床静态特性的一项重要指标,对保证机床的加工精度至关重要。数控机床比普通机床要求具有更高的静刚度和动刚度,有标准规定数控机床的刚度系数应比类似的普通机床高50%。基于有限元技术,在数控机床设计阶段,针对典型工况下切削力和重力作用下,对龙门机床立柱、横梁及主轴箱等大件结构进行静刚度计算,对结构设计预评估和优化。The static stiffness of machine tools is an important index to evaluate the static characteristics of machine tools,which is very important to ensure the machining accuracy of machine tools. Numerical control machine tools than ordinary machine tools require higher static stiffness and dynamic stiffness,there are standards that the stiffness coefficient of numerical control machine tools should be 50% higher than similar ordinary machine tools. Based on finite element technology,in the design stage of CNC machine tools,the action of cutting force and gravity under typical working conditions,the static stiffness of large structures of machine tools were calculated,and the structural design was pre-evaluated and optimized.
