| 为探究数控磨齿机的核心部件砂轮架主轴的静、动态特性对机床加工精度的协同影响，课题组采用ANSYS Workbench软件对磨齿机砂轮架主轴静、动态特性进行了分析与评估。以降低静态主轴前端最大变形，增加主轴系统的二阶固有频率和降低激振力所引起的主轴前端面Z轴方向振动幅值最大值为目标，展开基于参数敏感性筛选的响应面和多目标遗传算法(Multi Objective Genetic Algorithm，MOGA)的优化设计。实验结果表明：优化后，主轴静刚度增加了29.09%，二阶固有频率和临界转速均提高了2.73%，主轴前端面Z轴方向振动幅值最大值降低了22.34%，有效提升了机床的静、动态特性和加工精度。 |

| In order to explore the synergistic interplay between the static and dynamic attributes of the grinding wheel frame spindle, which is the core component within the CNC gear grinding apparatus, on the machining accuracy of the machine tool, the research group used ANSYS Workbench software to analyze and evaluate the static and dynamic characteristics of the grinding wheel frame spindle of the gear grinding machine. During the course of this investigation, objectives were met in terms of minimizing the maximal deformation of the static spindle front end, elevating the second order natural frequency of the spindle system, and mitigating the maximum Z axis vibration amplitude of the front end face of the spindle caused by the excitation force, through the implementation of parameter sensitivity screening based response surface methodology and Multi Objective Genetic Algorithm (MOGA) design. The experimental results show that the static stiffness of spindle increases by 29.09%, the second order natural frequency and critical speed both improve by 2.73% and the maximum Z axis vibration amplitude at the front end face of spindle decreases by 22.34% after optimization. These improvements have successfully enhanced the static and dynamic properties and processing accuracy of the machine tool. |
