【摘要】：行星轮式越障行走机构可应用于矿产开采运输。针对具有4组行星轮系组成的越障机构,机构轮系可根据不同地形状况在定轴和行星轮系之间转换。基于机构的行驶可靠性,采用模糊优化相关理论对行星轮系进行优化,确定机构的最优结构尺寸;建立机构在工作过程中的力学模型和稳定性力学模型。基于ADMAS建立了行星轮式越障机构虚拟样机和典型的地面谱(单边越0.45m障碍、0.45m壕沟、横坡道转向),对优化后不同工况下机构的稳定性进行分析。结果可知:行星轮式越障机构通过驱动轮系在定轴轮系和行星轮系间的转换,实现其越障、跨沟、爬坡等不同工况运行;不同运行工况下,机构的稳定性良好;分析结果为此类结构参数及控制参数确定提供理论基础。
[Abstract]:Planetary wheel-type obstacle-crossing mechanism can be used in mineral mining and transportation. For the obstacle crossing mechanism with four sets of planetary gear trains, the gear trains of the mechanism can be converted between the fixed axis and the planetary gear trains according to different topographic conditions. Based on the driving reliability of the mechanism, the fuzzy optimization theory is adopted to optimize the planetary gear train, to determine the optimal structure size of the mechanism, and to establish the mechanical model and the stability mechanical model of the mechanism in the working process. Based on ADMAS, the virtual prototype and typical ground spectrum of planetary wheel-type obstacle crossing mechanism are established. The stability of the mechanism under different operating conditions after optimization is analyzed. The results show that the planetary gear overstepping mechanism operates under different operating conditions, such as obstacle surmounting, crossing gully and climbing slope, and the stability of the mechanism is good under different operating conditions through the conversion of the driving gear train between the fixed axis gear train and the planetary gear train, and the mechanism is operated under different operating conditions, such as crossing the barrier, crossing the gully and climbing the slope. The results provide a theoretical basis for the determination of such structural parameters and control parameters.
