为了研究重载物流系统的水平,减轻工作人员劳动强度,提高生产率,以载重80 t的重载移动机器人为研究对象,对重载移动机器人整机进行了轻量化设计,利用有限元焊接仿真软件对车架纵梁进行不同焊接顺序的仿真模拟,通过对比仿真模拟结果可以发现,焊接顺序对焊接温度场、焊接变形、残余应力有一定的影响。采用双轮差速的设计方法对重载舵轮进行设计,实验结果表明:该设计方法减少了两轮转向时的磨损,增加了耐磨度。基于5G通讯技术并建立中国AGV行业5G通讯标准,使重载移动机器人实现多智能体协同感知更加顺畅,建立语义SLAM算法,实验表明:该算法为重载移动机器人提供环境的结构信息和自身的位置信息,实现重载移动机器人的户外运行。重载移动机器人创新设计对研究重载移动机器人有着重要的意义。

In order to study the level of the heavy-duty logistics system,reduce the labor intensity of the staff,and improve the productivity,taking the heavy-duty mobile robot with a load of 80 t as the research object,the lightweight design of the heavy-duty mobile robot was carried out,and the finite element welding simulation software was used.Simulations of different welding sequences were carried out on the longitudinal beams of the frame.By comparing the simulation results,it can be found that the welding sequence has a certain influence on the welding temperature field,welding deformation and residual stress.The heavy-duty steering wheel was designed by the design method of twowheel differential speed.The experimental results show that the design method reduces the wear of the two-wheel steering and increases the wear resistance.Based on 5G communication technology and the establishment of 5G communication standards in China′s AGV industry,the multi-agent collaborative perception of heavy-duty mobile robots was smoother,and a semantic SLAM algorithm was established,outdoor operation of heavy-duty mobile robot was realized.The innovative design of heavy-duty mobile robots is of great significance to the study of heavy-duty mobile robots.
