智能家居养老椅的结构设计与有限元分析

Structural Design and Finite Element Analysis of Intelligent Home Care Chair

针对目前国内外智能家居养老椅结构过于简单、实现功能单一且安全性能并未达到很好的市场要求,本文基于此提出了一种智能家居养老椅。首先通过优化动力学模型得到产品理论运动参数与受力情况,利用Solidworks软件建立机构三维模型,结合有限元仿真进行机构静力学强度校核。其次,对产品机构进一步优化,改善养老椅的舒适性能,降低产品受力损伤的概率。最后,搭建实物样机,并通过实地试验进行了性能检验。结果表明:该产品的实际运动参数误差小于7%,产品的工作具有可靠性并保证了工作的效率。

In view of the current domestic and foreign smart home endowment chair structure is too simple, achieve a single function and safety performance does not meet good market requirements, this pa-per based on this put forward a smart home endowment chair. Firstly, the theoretical motion pa-rameters and forces of the product were obtained by optimizing the dynamic model. Solidworks software was used to establish the three-dimensional model of the mechanism, and the static strength of the mechanism was checked in combination with the finite element simulation. Secondly, the product organization is further optimized to improve the comfortable performance of the endowment chair and reduce the probability of mechanical damage of the product. Finally, the prototype was built and the performance was tested by field test. The results show that the actual motion parameter error of the product is less than 7%, and the working efficiency of the product is guaranteed.
