基于Pareto最优原理的钻机钻进参数多目标优化
Multi-objective Optimization of Drilling Parameters Based on Pareto Optimality
摘要
Abstract
A multi-objective optimization of drilling parameters method based on Pereto principle was put forward to optimize horizontal directional drill machine.The optimization model of drill parameters was developed.Modifications were made based on NSGA-Ⅱ][due to the deficiency of penalty function method in handling constraints.Therefore,an effective constraints handling strategy utilizing constrained domination principle was introduced.To prevent premature,and accelerate the convergence speed towards optimal Pareto front,the original crowding distance calculation method was modified based on the niche concept.A new adaptive crossover and mutation strategy was put forward.Finally,the modified algorithm was applied to optimization model of drilling parameters which was built based on a coal mine.The results show that the modified algorithm has better convergence and distribution compared with NSGA-Ⅱ and MOPSO when solving test problems.The distribution of solution set is evenly when applying the algorithm to solve optimization model of drilling parameters.It improves the mechanical drilling speed effectively,extentes the life of drilling and decreases the energy ratio of drilling.关键词
