摘　　要：机床主轴箱的动静态特性优劣对机床整体精度具有重要影响。以数控卧式铣镗床侧向开口的主轴箱为研究对象,应用SolidWorks软件对主轴箱典型工况下的动静态特性进行分析;应用Simulation中的拓扑优化模块对主轴箱进行优化。对比优化前后的分析结果可知:主轴箱开口处是受力薄弱区域,优化后的主轴箱总质量降低了3.68%,最大变形量从0.059 mm降至0.051 mm;最大应力从18.4 MPa降至13.81 MPa,各阶振动频率均有所增加,振动幅度也有所改善,可有效避免共振。As the advantage and disadvantage of dynamic and static characteristics of machine headstock have an important influence on the overall accuracy of machine tool,taking the lateral opening headstock of NC horizontal milling and boring machine as the research object,analyzes the dynamic and static characteristics of headstock under typical working conditions by SolidWorks software,and applies the topology optimization module in Simulation to optimize the headstock.The analysis results of before and after optimization show that the headstock opening is a weak area,the improved headstock mass is reduced by 3.68%,the maximum deformation is reduced from 0.059 mm to 0.051 mm.The maximum stress also increases from 18.4 MPa to 13.81 MPa,the vibration frequency of each order increases,and the amplitude of vibration improves as well,which avoids resonance effectively.
