一种新型自动上下楼轮椅的力学分析

Mechanical Analysis of a New-type Automatic Wheelchair for Walking up and down Stairs

一种新型可自动上下楼梯的轮椅既适应平地行走,又能在无人陪同的情况下搭载使用者自动上下楼梯,极大地方便了老年人和腿脚不便人士的日常生活。新型轮椅在投入生产前必须要进行严格的测试分析,首先要满足轮椅上下楼梯的功能,对其平地行走和上下楼过程进行力学计算和动力分析,为其动力系统的选定提供数据支撑;同时也要保障人员在使用过程中的安全性,故要对其结构进行强度和刚度的校核并针对上下楼过程开展运动分析,以验证其安全性能。

A new wheelchair that can automatically walk up and down stairs is not only suitable for walking on flat ground,but also can carry the user up and down stairs automatically without accompanied, greatly facilitating the daily life of the elderly and the handicapped. The new wheelchair must be tested and analyzed strictly before it is put into production.First of all, the function of the wheelchair up and down the stairs should be satisfied, and the mechanical calculation and dynamic analysis should be carried out for the process of walking on the ground and up and down the stairs, so as to provide data support for the selection of its dynamic system. At the same time, it is necessary to ensure the safety of personnel in the process of use, so it is necessary to check the strength and stiffness of the structure and carry out movement analysis for the process of upper and lower floors to verify its safety performance.
