摘要
由于激光增材制造装备具有多维度信息、多流程、多功能、多对象等人机交互特征,导致其人机交互效率低、舒适安全性差,直接影响制件成形质量的稳定性。基于此,提出一种基于可达域的激光增材制造装备人机界面布局优化方法。依据双手垂直可达域的舒适性划分人机交互界面可达域等级,构建基于可达域的激光增材制造装备人机界面布局优化模型。针对基于域模型构建的多决策变量界面布局模型求解问题,提出一种基于狼群-粒子群算法的混合智能求解算法,将狼群算法的奔走围攻行为机制引入粒子群算法,解决粒子群算法因种群多样性较低而导致计算结果容易陷入局部最优解问题。最后,以LDM4030激光增材制造装备为例,对其人机界面布局进行优化,并进行工效学仿真与眼动试验,结果表明:优化后的人机界面布局在舒适性、安全性以及界面的合理性上都优于原装备的设计,验证了该模型的有效性和可行性。
Since the laser additive manufacturing equipment has multi-dimensional information, multi-process, multi-function,multi-objects and other human-computer interaction characteristics, which leads to low interaction efficiency, poor comfort and safety,and directly affects the stability of the forming quality of the parts. Based on this, a human-machine interface layout optimization method of laser additive manufacturing equipment based on reachable region is proposed. According to the comfort of both hands vertical reachable domain, the reachable domain level of human-computer interface is divided, and the human-computer interface layout optimization model of laser additive manufacturing equipment based on reachable domain is constructed. Aiming at the problem of solving the multi-decision variable interface layout model based on domain model, a hybrid intelligent solution algorithm based on wolf pack-particle swarm optimization algorithm is proposed. The running siege behavior mechanism of wolf pack algorithm is introduced into particle swarm optimization algorithm to solve the problem that the calculation results of particle swarm optimization algorithm are easy to fall into local optimal solution due to low population diversity. Finally, taking LDM4030 laser additive manufacturing equipment as an example, the human-machine interface layout is optimized, and the ergonomic simulation and eye movement experiment are carried out. The results show that the optimized human-machine interface layout is superior to the original equipment design in terms of comfort, safety and interface rationality, which validates the effectiveness and feasibility of the model.
