摘要

基于人体工程学原理,设计了八连杆坐卧姿态变换机构。为保证机构运行的稳定性以及获得较好的实用性能,针对八连杆姿态变换机构进行优化设计。根据八连杆姿态变换机构的工艺特性要求以及具体的约束条件和优化目标,构建了八连杆机构的数学模型,利用ADAMS/View建立了八连杆机构的优化设计模型,对八连杆机构进行了优化设计。从优化设计的结果和优化前后的连杆角度、速度、加速度曲线中看到,该优化设计与相应的人体工程学原理相吻合,达到了八连杆姿态变换机构的设计要求和目的。

Abstract

Based on the principle of human engineering,the eight-link mechanism with posture transformation of sitting and lying is designed. In order to ensure the stability of the mechanism and obtain better practical performance,the optimization design of the eight-link posture transformation mechanism is carried out.According to the process characteristic requirements,the specific constraint conditions and the optimization target of the eight-link posture transformation mechanism,the mathematical model of eight-link mechanism is constructed,the optimization design model of eight-link mechanism is established by using the ADAMS/View model,the optimization design of eight-link mechanism is carried out. From the results of the optimization design and the angle of the connecting rod,speed and acceleration curve before and after optimization,the optimization design coincides with the corresponding principle of human engineering, meeting the design requirements and purpose of the eight-link posture transformation mechanism.
