【Abstract】 The solid model and finite eement model of the rotor of vertical motor type of YKSL2150 are built with Pro/Engineer modeling system. Finite element simulation was completed based on the finite element model of the rotor with Msc.Patran/Nastran simulating system. Through the finite element simulation,the stress & strain & placement simulation parameters were obtained. Based on the simulation,the mechanical rigidity & strengthen of the rotor were checked,the main destroy form and dangerous location were analyzed. The results showed that the mechanical rigidity,strength & placement could meet the design requirement of the rotor. In the end,an optimization structure of the rotor was given and analyzed. This study is valuable for the development and design of the same type structure. 3figs.,1tab.,8refs.更多还原
