| Abstract: | Taking asynchronous traction motor for EMU 350 km/h as a example,basing on multi-physical coupling theory,the ANSYS software is adopted to take element analysis on the dynamic property and multi-physical field effect,and the optimization of guide bar and interference fit.In the numerical examples,the effect of parameters of key parts of the rotor,guide bar,end ring,retaining ring,on dynamic property of rotor has been discussed,and the stress distribution and deformation of the structure has been investigate... |
