上开式扇形闸门箕斗卸载曲轨曲线的参数优化

Optimal design of dump rail curve parameter of skip with up-open fan gate

以改善冲击力的均衡性和提高箕斗卸载的平顺性为优化目标,建立了上开式扇形闸门箕斗卸载曲轨曲线的多目标优化设计模型,并用理想点法进行了求解.优化后,卸载轮受的冲击力、卸载轮的运行加速度和加加速度都减小了,箕斗卸载过程的平稳性也得到了提高.

With the purpose of decreasing the average value of stress between dump wheel and dump rail and improving discharging smoothness,a multiple-target optimization model of dump rail curve of skip with up-open fan gate was developed and resolved by optimal point method.It is concluded that the average value of stress,the acceleration and jerk of dump wheel all become less after optimized,which then causes to discharge more smoothly.
