针对富存于深海底复杂地形的矿产资源,提出了车体转向式海底作业车技术方案,利用动力学仿真软件ADAMS/ATV,开发了海底作业车的三维动力学模型和虚拟样机,进行了海底作业车在障碍、沟和坡等典型地形上的仿真和分析。仿真结果表明,车体转向式海底作业车具有良好的越障、越沟、爬坡和转向性能,各项技术指标超过我国复杂地形海底作业车的技术要求,为海底作业车样机研制提供了技术支撑。 Aiming at the mineral resources rich in complex terrain on the deep sea floor, the technical scheme of steering body for seabed works is proposed. By using the dynamic simulation software ADAMS / ATV, the three-dimensional dynamic model and virtual prototype of the underwater working vehicle are developed. Work vehicles in the obstacles, ditch and slope and other typical topographic simulation and analysis. The simulation results show that the vehicle steering submarine work vehicle has good obstacle crossing, overturning, climbing and steering performance, the technical indicators surpass the technical requirements of our country’s complex terrain submarine operating vehicle, and provides technology for the prototype of submarine work vehicle support.
