| Abstract: | Based on the Timoshenko beam theory considering the rotary inertia and the shear deformation, the simplified model of a high-speed spindle system was established.After determining the optimum span of front supporting bearings by contrast analysis,the effect of adding support in different locations on the lower-order natural frequency of the main shaft was analyzed under the different preloads,which provided a academic basis and feasible analytical method for researcher and designers. |
