摘要:
针对现有电铲自主装卸功能在料堆重构、环境感知、目标识别等领域存在技术难度的现状,从降低自主装卸作业任务难度的角度出发,本文提出了一种以载荷均衡分布为目标的矿用自卸车斗型优化方法。首先,构建了一种基于差分迭代的装卸后自卸车斗内料堆的轮廓重构方法,并对料堆质心位置进行计算;其次,建立并验证了模拟电铲装卸过程的离散元仿真方法;再次,利用离散元仿真实验,研究了不同斗型结构参数对斗内料堆质心位置的影响;最后,以横向载荷均布为目标,以纵向载荷分布、行驶安全性、斗容变化为约束对斗型进行优化。结果表明:优化后的斗型与原斗型相比,在保持装载能力和行驶安全性的前提下,极端装卸位置时的载荷分布均匀性显著提升,并具有更大的合理装卸面积和更高的作业效率。
