Strength and Modal Analysis of Vibrating Screen Frame Using ANSYS
TQLMz125 vibrating screen is used for cleaning wheat impurities in flour mill.The frame is a vital part of the vibrating screen,which primarily plays a carrying role.Its stiffness,strength and consistency are of huge essentiality to the reliable operation which is vibrating screen.For the purpose of verifying the feasibility of frame structure design,ANSYS software has been used for analyze the frame finite element,and the stress,strain and inherent frequency of the frame are obtained.The results indicate that the uttermost stress of the frame is 0.041 6 MPa,which is far less than the allowable stress,and the structure of the frame can satisfy the strength design.Through modal analysis,the minimized inherent frequency of the frame is 21.866 Hz,which is higher than the vibration frequency of the motor 12.5 Hz,avoiding resonance between the motor and the frame,which is for the later optimization frame as the basis.
