Research on Finite Element Analysis and Structural Optimisation of Coal Mine Hoisting Winch Drums
Taking the drum structure of JTB-0.8 × 0.6A hoisting winch as the research object,a brief overview of the hoisting winch and the drum structure was conducted,and the numerical model of the drum structure was established by using SolidWorks and ANSYS software.It is found that the maximum stress of the drum is 231.45 MPa and the maximum deformation is 1.302 9 mm,and the maximum stress is almost close to the permissible stress of No.45 steel 237 MPa,so the drum is prone to failure problems.According to the latest specification and empirical formula,the optimised design of the drum diameter and width were calculated to be 3,000 mm and 3,752 mm respectively,and the numerical analysis of the optimised drum structure showed that the maximum stress and deformation were reduced by 20.65％and 19.77％respectively.The optimised drum structure was applied to the hoisting winch engineering practice and found to achieve the expected results.
