摘　　要：双驱进给系统在各类机床上的应用越来越广泛,系统静态特性对机床该方向的定位精度影响很大。运用ANSYS Workbench软件对FMXT-2000落地镗铣床的y向双驱进给系统进行静态分析,根据所得数据拟合补偿曲线。经试验证明,补偿之后的定位精度可达到0.008 mm,高于国家标准要求。依据分析结果,考虑切削力、主轴箱质量及滚珠丝杠副刚度对y向双驱进给系统的影响,提出了几种优化方案,可供同类镗铣床垂直进给系统的设计和改进时参考。The dual-drive feed system is more and more widely used for various types of machine tools,and the static characteristics of the system have a great influence on the positioning accuracy of the machine tool in this direction.The ANSYS Workbench software is used to statically analyze the y-direction double-drive feed system of the FMXT-2000 floor boring and milling machine,and the compensation curve is fitted according to the obtained data.Test results show that the positioning accuracy after compensation can reach to 0.008 mm,it is over the national standard.According to the analysis results,considering the influence of cutting force,spindle box mass and ball screw stiffness on the y-direction double-drive feed system,several optimization schemes are proposed,which can be used as reference for the design and improvement of the vertical feed system of similar boring and milling machines.
