Abstract
Based on thedisassembling toy bricksmechanics model and the bearings' stiffness matrix which is built by simulated static mechanics,the structure design of the machine tool spindle was optimized. The calculational task was considerably reduced by the proper mathematical transformation. It was verified to be available for machine tool spindle's volume and stiffness's optimizing design through the analyses and calculations of various machine tool spindle systems. The result of this paper was tested on the M2110A inner grinding machine.
