Finite Element Analysis of Mixing Arm and Shaft Based on ANSYS

The screw shaft is the main structure of the horizontal dryer used in polysilicon industry. It is the key factor for dryer to work normally that strength and stiffness of shaft and mixing arms meet the standard. According to material properties and working environment, the models of shaft and mixing arm were built respectively by ANSYS. The deformation and stress distribution were obtained through finite element analysis which provided reference for design and optimization. The results show that the shaft and mixing arm satisfy the requirement of strength and stiffness.
