摘要: |
下肢运动障碍患者康复训练治疗手段之一是减重步行训练,移动式下肢康复训练机器人既可以跟随保护患者,又可以对其进行减重步态训练。针对机器人核心部件之一的减重单元,本研究提出一种启发式设计算法,可以避免机构本身复杂因素所带来的结构优化困难,获得多目标的优化解集。通过带精英策略的非支配排序遗传算法(NSGA-Ⅱ)在多目标优化问题中确定减重单元的设计参数。实验验证表明,减重单元体积减小明显,使结构更加紧凑。 |

Abstract: |
One of the rehabilitation training treatments for patients with lower limb movement disorders is weight reduction walking training.A mobile lower limb rehabilitation training robot can not only follow and protect patients,but also realize weight reduction gait training for them.For the weight reduction unit,one of the core components of the robot,a heuristic design algorithm is proposed in this study,which can avoid the structural optimization difficulties caused by the complex factors of the mechanism itself and obtain the multi-objective optimization solution set.The design parameters of the weight reduction unit mechanism are determined in the multi-objective optimization problem by the non-dominated ranking genetic algorithm with elite strategy (NSGA-Ⅱ).The experimental verification shows that the volume of the weight reduction unit is reduced significantly,resulting in a more compact structure. |
Key words: multi-objective optimization mechanical structure optimal design medical-industrial integration NSGA-Ⅱ |
