六杆搁脚机构的设计与优化

Design and Optimization of Six-bar Leg-supporter Mechanism

针对众多休闲椅搁脚机构在运动过程中平稳性较差,状态较难保持等问题,结合人机工程学理论设计了一种新型的六杆搁脚机构,并建立了六杆搁脚机构的数学模型,之后在ADAMS中进行参数化设计,利用Insight进行多目标优化。根据优化结果,修改模型,再次仿真,进行前后对比。结果表明,优化后的新型的六杆搁脚机构能够平稳运行,符合设计要求。

For the most of the leg - supporter mechanism of leisure chairs, it cant run smoothly during the movement and hard to keep working condition etc. Aiming at these problems, a new six - bar leg - supporter mechanism is designed based on the theory of ergonomics, the mathematical model is established. Then the multi- objective optimization of mechanism is carried out by using Insight after the parametric design in ADAMS. According to the optimization results, the model is modified and simulated again, then comparing the data before and after optimization. The results show that after optimization, the new six - bar leg - supporter mechanism can run smoothly and meet the design requirement.
