中文摘要:
      目的 减少学龄前脑瘫儿童助行器的安全隐患,解决患儿在训练过程中的肢体二次损伤问题,提升助行器人机舒适性,对学龄前脑瘫儿童助行器进行优化设计。方法 通过JACK虚拟仿真软件的RULA工具,分析得到学龄前脑瘫儿童在使用助行器过程中存在的不合理姿势,并对其进行人机工学与受力分析,提出改进方法并进行设计优化,最后导入JACK虚拟仿真软件进行风险与舒适性验证。结果 优化后的学龄前脑瘫儿童助行器的使用受伤风险从4级降低到1级,患儿躯干弯曲力矩、L4/L5脊柱压缩力、剪切力的姿势载荷指数分别降低53%、47%、81%,上身各关节处于舒适角度。结论 经过JACK仿真分析及人机优化后的助行器,有效降低了学龄前脑瘫儿童在康复训练中的二次损伤风险,减轻了患儿步行训练中的身体负担,提升了助行器使用的舒适性。
英文摘要:
      The work aims to optimize the design of walking aids for preschool children with cerebral palsy, in order to reduce the potential safety hazards of walking aids for preschool children with cerebral palsy, solve the problem of secondary injury of limbs in the training process and improve the comfort of walking aids. Through the analysis by the RULA tool of the JACK virtual simulation software, the unreasonable postures of preschool children with cerebral palsy in the process of using the walking aids were obtained, the ergonomics and force were analyzed, the improvement methods were proposed and the design was optimized, and finally the JACK virtual simulation software was imported to verify the risk and comfort. After optimization, the injury risk of preschool children with cerebral palsy using walking aids was reduced from grade 4 to grade 1, the postural load index of the children's trunk bending force, L4/L5 spinal compression force, and shear force decreased by 53%, 47%, and 81% and each joint of the upper body was at a comfortable angle. After JACK simulation analysis and ergonomic optimization, the walking aids effectively reduce the risk of secondary injury in the rehabilitation training of preschool children with cerebral palsy, reduce the physical burden of children in walking training, and improve the using comfort.
