Finite Element Analysis And Lightweight For Wheel Body Of The Hoist

As to continuously expand to the deep mining of mineral resources,large floor type multi-rope friction hoist in has an increasing proportion of lifting equipment, the hoisting sheave system as its an important composition part, to a great extent, affecting the whole system increased efficiency, cost, service life, safe, reliable, performance on speed adjustmenand so on. Have completed kinds of simulation analysis and scene tests on the hoisting sheave system by high precision technology. The premise of the precondition of guaranteed safety and reliability, realized the hoisting sheave system lightweight large and structure optimization.This has a certain engineering significance to meet the demand of mining industry.The paper simply introduced the hoist equipment development history, focued on researching large floor type multi-rope friction hoisting system, with JKMD-5.7x4(IV) large pulley system as the study object, detailed analysis of its working principle, working environment, and the stress distribution. Based on the finite element theory, using CATIA established geometric model for the hoisting system, imported ANSYS and established finite element model, through the statics analysis, it is concluded that the stress and strain condition of the normal working conditon. For the purpose of lightweight structure optimization. Statics analysis and modal analysis of the optimized system to check its preliminary intensity. Combined with the actual conditions, under normal working conditions, though dynamic test on the JKMD-3.5x4(type III) pulley system. At the same time adopted combination of ANSYS and ADAMS software, used the rigid-flexible coupling mode for JKMD-3.5x4(III) hoisting sheave system to dynamic analysis, compared to scene test and the simulation data, after error analysis, then verified that the dynamic analysis process with high accuracy and reliability. Then completed dynamic test on JKMD-5.7x4(IV) before and after optimization the large hoisting sheave system in normal working conditions, by the same simulation method. After analysis the stress and strain, further checking strength of the hoisting sheave system.Based on the finite element, the effective combination of CATIA, ANSYS and ADAMS software to the hoisting sheave system modeling analysis,integrated the cannot make up for the drawback of the research. Also predicted the optimized system that the system could occur stress and strain during the work, etc. Successful weight loss by2.55%. Realized lightweight, low cost and to enhance the efficiency of the manufacturing economy. The paper enriched the traditional product analysis, designed method, upgraded the innovation of the manufacturing industry of our country’s lifting equipment and also had a certain promoting role and significance on new product development manufacturing.
