悬臂式掘进机回转机构的优化及其疲劳特性
Optimization of slewing mechanism of cantilever roadheader and its fatigue characteristics
摘要
Abstract
This paper intends to improve the cutting performance of roadheading,a mathematical model with the parameters of rotary radius and cantilever length is established,and the particle swarm al-gorithm is used to optimize the parameters of the rotary mechanism of the roadheader,Ls-Dyna is used to simulate the drilling and swing cutting of the cutting head of the roadheader.The three-directional load spectrum characteristics of the cutting head are analyzed using EEMD and sample entropy,and the fa-tigue life of the rotary table before and after optimization is compared and analyzed according to the simu-lated loads combined with the ANSYS-Workbench.The fatigue life of the rotary table before and after op-timization is compared and analyzed by combining ANSYS-Workbench with simulated loads.The results show that:the minimum fatigue life increases by 9.1%and the minimum safety factor improves by 5.5%after the optimization of drilling pure coal;the minimum fatigue life increases by 17.2%and the mini-mum safety factor improves by 10%after the optimization of drilling gangue;the minimum fatigue life in-creases by 10.4%and the minimum safety factor increases by 4.9%after the optimization of cutting pure coal;the minimum fatigue life increases by 15.7%and the minimum safety factor increases by 6.1%af-ter the optimization of cutting gangue.The difference of rotary torque becomes smaller,the stability of the rotary mechanism is improved,and the mechanical characteristics of the rotary mechanism are improved.关键词
