【摘要】：海底车作为深海矿产开采的重要设备,面对复杂的海底地形,海底车行星轮系执行机构需完成跨沟、越障、上下台阶等多种复杂动作。根据海底行星轮式行走机构的性能特点和传动特点,建立行星轮系越障静力学模型和力学平衡方程,对轮系工作行走机构完成跨沟、越障、上下台阶等多种复杂动作进行动作设计和工况分析。基于ADMAS建立了轮组行走机构的系统仿真模型,选取车辆单边越障、车体跨越900mm壕沟、坡度为42°行星轮行走机构爬坡过程等工况进行分析。分析结果表明:行星轮系动作执行系统越障时整车的运行工况良好,安全可靠完成设计目标要求。设计分析过程可以为海底车行星轮系动作执行系统的设计优化及其他相关的研究提供理论依据和参考。
[Abstract]:Submarine vehicle is an important equipment in deep-sea mining. In the face of complex submarine topography, the actuators of undersea vehicle planetary gear train need to complete a variety of complex actions, such as crossing trenches, surmounting obstacles, going up and down steps, and so on.According to the performance characteristics and transmission characteristics of submarine planetary wheel walking mechanism, the statics model and mechanical balance equation of planetary gear train are established.A variety of complex actions, such as up and down steps, are designed and analyzed.The system simulation model of wheel group walking mechanism is established based on ADMAS. The working conditions such as vehicle crossing obstacles, vehicle body crossing 900mm trench and slope of 42 掳planetary wheel walking mechanism are selected for analysis.The analysis results show that the running condition of the whole vehicle is good when the planetary gear train action execution system overcomes the obstacle, and the design goal is fulfilled safely and reliably.The design and analysis process can provide the theoretical basis and reference for the design optimization and other related research of the action execution system of the planetary gear train of submarine vehicle.
