In order to reduce the vibration intensity of the traditional spinning spindle of a company,the method of rigid- flexible coupling was used to build the dynamic model of electric spindle; the system vibration characteristic analysis was finished by using the combining simulated technique of Adams and Ansys, to get the forced vibration amplitude frequency characteristic ,then uses the damping buffer vibration damping technology and the high speed gyro stabilization technology to improve the structure of electric spindle,sofiware verification and test Validation on the optimization results. Experimental results shows： the structure optimization is practical and effective. For spinning electric spindle centrifuge technological progress provides design basis and the successful case of the experience ,the mare important is to bring huge economic benefits for the development of independent equipment of spinning industry.
