Abstract


As China has entered the aging society , the elderly, the day-to-day health care issues become more prominent, especially as one of the most important day-to-day care of a bath . Developed personal hygiene care robots , relieve nurses of labor intensity , improve the quality of life of older people , become increasingly important . Optimize the design based on the numerical simulation of the flow field bath cabin structure is an important part of the personal health care robotics research . In this paper, based on a full analysis of the overall structure and function of personal health care robots , bath cabin 3D CAD design , bath cabin structure and different and out of the water with the surface of the human body interaction forms to determine bath cabin bath four water cycle mode , model bath cabin and human computing reasonable simplification , the establishment of a four cycle mode limited space - bath cabin CFD computational model , calculated by the numerical simulation of three-dimensional flow field obtained various water cycle mode under the speed of the body near the surface trace chart maps intake and body near the surface at different speeds corresponding to the proportion of area maps , quantitatively in terms of time and space given the bath cabin body around stream the numerical solution of the field changes , determine the best bath cabin bath mode . Combined with the results of the CFD simulation and optimization design theory , human DOE ( orthogonal experimental design ) optimization model based on computational fluid dynamics bath cabin - as a platform to establish multidisciplinary optimization software iSIGHT , bath cabin structural optimization , optimization fluid calculated after bath cabin structure analysis , comparative analysis of the optimization results before optimization . The results show that the optimized design to meet human comfort , bath cabin bath effect , the inlet and outlet layout more reasonable , provide the theoretical basis of the the bath cabin overall structure design and bathing mode . Flow field simulation and optimization results bath cabin - the limited space of the human body , bath cabin overall structural design , including: bath cabin , care seat , entrance to the auxiliary institutions , automatic shampoo agencies design and exterior design , developed the personal health care for the elderly to use robots bath cabin prototype .
