摘　　要：针对某企业传统纺丝电锭离心机轴承疲劳寿命低的问题,采用阻尼缓冲减振技术和高速陀螺稳定调心技术对电锭结构进行改进。以现代计算机仿真模拟技术为基础,通过Adams软件对纺丝电锭系统进行动力学分析以提取轴承的受力信息,再运用Matlab/Simulink模块计算轴承的疲劳寿命,对改进结果进行软件验证。实验结果表明:该结构优化实用,有效。Aiming at the traditional spinning electric spindle centrifuge of a certain enterprise has theproblem of low bearing fatigue life,using the damping buffer vibration damping technology and the highspeed gyro stabilization technology to improve the structure of electric spindle. On the basis of moderncomputer simulation technology, the system dynamic characteristic analysis was finished by usingAdams in order to extract the information of bearing force. Then use the Matlab/Simulink module tocalculate bearing fatigue life. And software verification on the improvement. Experimental results shows：the structure optimization practical, effective.
