摘要
针对如厕时,老年人可能会发生因久坐而起身困难甚至跌倒的情况,设计了一种智能马桶升降辅助装置.利用SolidWorks对装置进行了三维建模,分析了装置的工作机理并对关键部件的强度进行了有限元分析.有限元分析表明:升降连接杆最大应力为64.231 7 MPa,因 HT200的屈服应力范围在100～300MPa,所以远小于HT200的屈服应力,满足要求.该装置的设计解决了老年人如厕问题,为此类装置的设计提出了有效解决方案,并且增加了装置升降过程中的平稳性,相比于市场上的同类产品,该装置在提高升降平稳性及用户舒适度方面具有显著优势.
Abstract
A smart toilet lifting assistive device is designed for the elderly who may have difficulty getting up or even fall down due to sitting for a long time when using the toilet.SolidWorks was used to model the device in three dimensions,analyse the working mechanism of the device and carry out finite element analysis on the strength of key components.The finite element analysis shows that the maximum stress of the lifting connecting rod is 64.231 7 MPa,which is much smaller than the yield stress of HT200 because the yield stress of HT200 is in the range of 100～300 MPa,and meets the requirements.The design of this device solves the problem of toileting for the elderly,proposes an effective solution for the design of such devices,and increases the smoothness of the device during lifting and lowering,compared with similar products on the market,the device has significant advantages in improving the smoothness of lifting and the comfort of the user.
