摘要: 设计了一种其构造集滑行、爬行、滚动多种运动模式的仿生多模式移动机构:基于仿生原理,以四足步行、扑翼飞行、圆形滚动生物的运动方式为仿生对象,抽象出与仿生对象等效的运动结构单元,并通过螺旋理论进行构型设计分析,结合空间几何对称原理和变自由度思想将两个等效单元体对称布置组成多模式移动机构.仿真结果表明,该机构能够实现预期的运动模式,设计合理,具有良好的稳定性和机动性.Abstract: A bionic multi-mode moving mechanism was designed, which can realize the sliding, crawling and rolling sports modes.Based on the principle of bionics, the four-legged walking, flapping wing, and circular rolling creatures were used as bionic objects to abstract the motion structural unit equivalent to the bionic object.Through the screw theory of configuration design analysis, combined with the spatial geometric symmetry principle and the variable degree of freedom idea, the two equivalent unit bodies were symmetrically arranged to form a multi-mode mobile mechanism.The simulation results showed that the mechanism could achieve the expected motion mode, reasonable design, good stability and maneuverability.
