A calculation method for the dynamic rigidity of angular contact ball bearings was put forward and realized.By using the method,the mechanism of how the dynamic rigidity is affected by the preload of bearings and rotation speed was effectively investigated.The dynamic model of a high-speed spindle system was built on the basis of analysing the dynamic rigidity of high-speed bearings,and an integrated optimization design method for the work performance of the high-speed spindle was proposed.In the method,the dynamic rigidity of bearing,spindle bearing configuration,working speed limiting factor,structural parameters of spindle,grinding process for flexible connector necking and demand on accuracy of high-speed spindle were comprehensively considered to analyse quickly the key factors affecting the work performance of spindle and to inspect the coupled relations among these factors.So that,the weakness in the design scheme of high-speed spindle can be accurately identified and the influential key factors and their correspondent values can be effectively determined in a coordinated fashion.The study lays a foundation to realize the design of high performance spindle systems.
