【Abstract】 Vibrations and calculating methods of critical speeds of agitating shaft are discussed. A system function of simulated girder-tray FE model is conducted through force analysis, then critical speeds of two shafts are calculated through FEM, HG/T20569-94 and EEUA-FMP method. The correctness and efficiency of FEM is proved by analyzing the results of three methods.更多还原
