摘要为提高电主轴系统刚度和抗振能力，提出一种由磁悬浮轴承和角接触球轴承共同支撑的复合支撑电主轴，通过球轴承保证主轴系统刚度，引入磁轴承控制系统对主轴振动进行抑制，实现电主轴系统在球轴承低预紧状态下仍具有较好的动态性能。基于ANSYS模态分析、谐响应分析和瞬态动力学仿真，分析了不平衡质量引起的振动响应，比较了磁-球轴承复合支撑电主轴和球轴承支撑电主轴的振动特性。搭建复合支撑电主轴试验平台，对该复合支撑电主轴进行振动特性测试与分析。结果表明：复合支撑电主轴与球轴承支撑电主轴相比，复合支撑系统可以有效提高转子的临界转速、降低转子的振动幅值和球轴承应力，使电主轴具有较高的动态刚度。

Abstract：In order to improve the stiffness and vibration resistance of the motorized spindle system, a composite supported motorized spindle supported by magnetic levitation bearing and angular contact ball bearing is proposed. The stiffness of the spindle system is ensured by ball bearings, and the magnetic bearing control system is introduced to suppress the spindle vibration. It can realize that the electric spindle system has good dynamic performance under the condition of ball bearing low preload. Based on ANSYS modal analysis, harmonic response analysis and transient dynamics simulation, the vibration response caused by unbalanced mass is analyzed, and the vibration characteristics of the magnetic bearing and ball bearing composite supported motorized spindle and the ball bearing supported motorized spindle are compared. The test platform of composite supported motorized spindle was built, and the vibration characteristics of the composite supported motorized spindle were tested and analyzed. The results show that, Compared with the ball bearing supported motorized spindle, the composite support system can effectively improve the critical speed of the rotor, reduce the vibration amplitude of the rotor and the stress of the ball bearing, so that the motorized spindle has higher dynamic stiffness.

Key words： magnetic bearing composite support motorized spindle harmonic response analysis;vibration characteristics
