直线型连杆爬升机构的设计与分析

Design and Analysis of Linear Connecting Rod Climbing Mechanism

通过与现有电动爬楼轮椅的爬升机构的对比与分析,提出了直线型连杆爬升机构。对直线型连杆爬升机构进行设计研究,其端点轨迹上半部分为半圆形,下半部分为近似直线的弦,该轨迹与动物行走步态极其相似;将其作为爬升机构的设计基础,并利用SolidWorks软件对直线型连杆爬升机构进行建模,并对爬升机构在爬楼梯过程的轨迹进行了分析。结果表明,该爬升机构设计方案合理,爬升机构爬升运动轨迹近似直线,较大程度降低了颠簸,为爬楼机构的设计提供了新的理论参考。

Based on the comparison and analysis with the climbing mechanism of the existing electric wheelchair,the linear connecting rod climbing mechanism is proposed.The design research of linear connecting rod climb mechanism is carried out,the endpoint trajectory upper part as the semicircle,the approximate linear the lower part of the string,the trajectory and animal walking gait extremely similar,so use it as a climbing mechanism design basis,and by using the SolidWorks software climb straight connecting rod mechanism modeling,and during the process of climbing stairs trajectory of climbing mechanism is analyzed.The simulation results show that the design scheme of the climbing mechanism is reasonable,the climbing trajectory of the climbing mechanism is approximately linear,and the turbulence is greatly reduced,which provides a new theoretical reference for the design of the climbing mechanism.
