Research on Finite Element Analysis and Structural Improvement of Belt Conveyor Roller
Based on the overview of the belt conveyor roller structure,the finite element model of the roller was established by ANSYS software.It was found that the strength of both the tube body and the bearing seat could meet the permissible requirements,but the stiffness exceeded the permissible requirements.The optimisation of the roll mechanism is carried out by setting a 25 mm thickness web structure in the middle region of the tube body,and it is found that the maximum stress and deformation are greatly reduced after optimisation,and the stiffness of the structure can meet the requirements.The improved roller structure is applied to the belt conveyor engineering practice,through the 6-month on-site commissioning,it is found that the roller structure has a good operating effect,and the expected service life can be extended by about 20％,which can create good economic benefits for the enterprise.
