【摘要】：提出一种改进遗传算法,即在传统遗传算法中融入非均匀变异算子和小生境运算,可使解有效地朝着最优化运行,且更好地保持解的多样性和较高的收敛速度,并且将铲板宽度、铲板倾角及围板厚度作为设计变量,对铲板的铲掘力、装载能力进行多目标优化设计。优化结果表明:优化后铲板宽度降低1.33%,铲板倾角降低9.47%,而铲板围板厚度增加10.4%,这将对掘进机整机稳定性和铲板强度有显著效果;铲板铲掘力提高4.72%,铲板装载能力提高5.12%,改善了掘进机装载机构的综合性能,符合眼下掘进机铲板设计的趋势。同时,在Pro/E,ADAMS,ANSYS协同仿真环境下了优化后铲板的可靠性。
[Abstract]:An improved genetic algorithm is proposed, which is in the traditional genetic algorithm with non-uniform mutation operator and niche operation, can make the solution effectively toward the optimal operation, and better maintain the convergence speed and higher diversity, and the angle and thickness of plate width, shovel shovel coaming plate as design variables, multi optimization design of loader shovel shovel digging force, ability. The optimization results show that the width of the shovel board decreased by 1.33% after optimization, shovel plate angle is reduced by 9.47%, and the shovel plate baffle thickness increased by 10.4%, which will have a significant effect on the stability of tunnelling machine and shovel plate strength; shovel shovel capacity increased by 4.72%, the ability of loading shovel plate is increased by 5.12%, improve the comprehensive performance of loading mechanism of roadheader now, with the shovel board roadheader design trends. At the same time, the reliability of the rear shovel is optimized in the Pro/E, ADAMS and ANSYS collaborative simulation environment.
