| Abstract: | Based on the impellers of a PTA RPF circular blower,the finite element calculation and analysis were made of the assemble stress,dynamic stress in operation,and inherent frequency of the interference fit of the impeller and shaft using 3D finite element method.The stress distribution,deformation,and improvements of the whole impeller were emphatically analyzed,a theoretical basis was provided for the design of the impellers in strength to improve the structure of the impellers. |
