【Abstract】 Based on the "disassembling toy bricks "mechanics 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.更多还原
