This paper shows the mechanical design of a mechatronic system focused on providing assistance to older adults with motor disabilities. The main objective is to keep these people standing on their lower extremities, facilitating their mobility and at the same time providing greater support to their body structure. The mechanical design of the permanent station was developed using CAD (Computer Aided Drawing) software, including concept design, structural analysis and selection of mechanical actuators; elements designed for this mechatronic system. In addition, it shows the study to ensure ergonomics and safety for users using standards UNE-EN ISO 10535-2006, UNE-EN IEC 60601-1-2010 and EN 13480-2-2002 with the compliance of a structural safety factor through the software CAE (computer-assisted engineering), as well as the adaptability of the design of the system to the various anthropometric measures of the world demographic environment.
The article focuses on the evaluation of impact loads to the structural design of a conventional food truck through static lateral collision tests with dynamic and static study based on several requirements and regulations of the international standard (ECER95) where force determine of impact generated laterally in a totally inelastic. The physical variables that interact in this phenomenon with the variation of mass, velocity and determine their real impact are analyzed with mathematical equations. The validation of the combined loads was developed by CAE software applying the LRFD method complying with Regulation No. 95 of the Economic Commission for Europe (UNECE) of the United Nations with a collision between the stationary conventional food truck and a vehicle, which impacts it at 50 km / h where the deformations under United Nations Regulations No. 95 and No. 66 are determined, guaranteeing the occupants survival.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
