辅助站立装置的设计与研究

Design and research of auxiliary standing device

随着老龄化社会的来临,老年人的日常独立生活备受关注。其中,生活中重复较多的坐立动作已成为越来越多老年人,特别是患有脊椎腰椎损伤、骨质疏松、腿部疾病的老年人不得不面对的严峻挑战。基于此,提出了一种辅助人体站立的装置,旨在帮助老年患者完成频繁的坐立动作。首先,分析了人体自然站立的运动学过程,建立了简化的人体站立数学结构模型,通过自然站立实验测定了人体膝关节的角度变化特性。其次,基于人体自然站立过程的运动学特性设计了一款人体辅助站立装置,并运用Solidkworks软件完成了机构的三维建模。最后,采用ADMAS软件进行运动仿真,确定了人体辅助站立装置的运动参数。通过实验和仿真数据对比可知,该装置符合人体自然站立的运动学规律,具有一定的辅助站立功能,可以运用在一些特定的场合如站立康复训练、久坐场合等。

With the advent of an aging society,the daily independent life of the elderly has attracted much attention.Among them,sitting movements are repeated in daily life,which is a serious challenge that more and more elderly people,especially those with spinal and lumbar vertebral injuries,osteoporosis,leg diseases,have to face.Based on this,this paper puts forward a kind of human-assisted standing device,which aims to help the elderly complete frequent sitting and standing movements.Firstly,the kinematics process of human body natural standing is analyzed,and a simplified mathematical structure model of human body standing is established.Then,the angle change characteristics of knee joint are measured by human body natural standing.Secondly,based on the kinematics characteristics of human natural standing process,a human assistant standing device is designed,and the three-dimensional modeling of the mechanism is completed by using software Solidworks.Finally,software ADMAS is used to complete the motion simulation,and the motion parameters of the human body auxiliary standing device are determined.By comparing the experimental and simulation data,it can be seen that the device can satisfy the kinematics law of human natural standing,and has certain auxiliary standing function.It can be used in some special occasions,such as standing rehabilitation training,sedentary occasions,etc.
