面向士兵体力增强的单兵助力机器人设计

Analysis of Individual Soldiers’Power Assisted Robot for Soldiers’Physical Strength Enhancement

为了解决士兵负重携行时体力消耗过大,易于出现骨骼肌肉损伤的问题,设计了一款士兵体力增强的无动力助力机器人,可实现士兵负重能力与持续作战能力的提升。结合人体运动负重原理,采用相容性的机构设计、变刚度的柔性仿生脊柱设计、四边形铰链式结构的自适应膝关节设计等关键技术,对单兵助力机器人采用了拟人化结构设计,确保了与士兵的有效融合,能够协助士兵在战场上负载装备而不影响其战术动作;利用ANSYS软件对其关键零/部件进行强度分析,以验证整体结构设计的稳定性和正确性,仿真结果表明,单兵助力机器人安全可靠,能够有效协助士兵携行负重。对单兵助力机器人的应用前景进行了分析,对士兵体力增强的研究具有一定的指导意义。

In order to solve the problem of excessive physical consumption and skeletal muscle injury when soldiers carry heavy load,a powerless power assisted robot for soldier’s physical strength enhancement is designed,which can improve soldiers’load-bearing ability and sustainable combat ability.Combined with the principle of human motion load-bearing,the compatible mechanism design,flexible bionic spine design with variable stiffness,adaptive knee joint design with quadrilateral hinge structure and other key technologies are used,the humanoid structure design is adopted for the individual soldiers power assisted robot,which ensures the effective integration with soldiers,and can assist soldiers in loading equipment on the battlefield without affecting the tactical actions.The ANSYS software is used to analyze the strength of the key spare parts components to verify the stability and correctness of the overall structure design.The simulation results show that the individual soldier power assisted robot is safe and reliable,and can effectively assist soldiers in carrying loads.Finally,the application prospect of the individual soldiers’power assisted robot is analyzed,which has a certain guiding significance for the research of soldiers'physical strength enhancement.
