The object of the study is a lift for people with special needs. The article is an overview and is devoted to the review of the construction of a lift for people with special needs, namely people who cannot stand up and/or move independently or people who have problems with the musculoskeletal system and vision for changing its functionality. It is assumed that the lift proposed inthis article will be equipped with a transforming chair and a remote control. Such a lift will help both people with special needs themselves and those around them who are forced to help with similar lifts. To do this, at the beginning of thearticle, different types of lifts are considered with all the characteristics, where the shortcomings of a particular device are clearly visible. Also selected lift, which is improving. The lift, chosen as the closest analogue, is intended for treatment with hydrotherapy. Therefore, it is suitable for moving a person from one point to another and letting down a person into the pool. However, this lift also has disadvantages, such as: a need of a person who will operate the lift; absence of a mechanism to help people get upright from sitting, because in this case there is no such need. Further, a device that changes the trajectory of the movement of the very arm of this lift, followed by an explanation of its operation is proposed. And the main goal is to develop a transforming chair, taking into account the height and weight of a person, as well as easy control and paying great attention to the safety of such a lift with a transforming chair, namely its stability and insurance of the person sitting in the chairof such alift when the patient's position changes. A remote control will also be offered with large buttons, voice and simple controlsfor easy self-use by a person with special needs, allowing it to be used by a wider range of patients
The article contains a scientific and methodical study on the installation of machines tool and other equipment directly on antivibration supports and the selection of specific types of these supports based on comparative evaluation and with confirmation of their compliance with operational requirements. The results of the research are relevant and can be applied by engineeringand technical workers of machinery manufacturing plant in the case of modernization of existing equipment, primarily at small enterprises, since the solution of the problem should not involve complex dynamic studies and calculationsthat require appropriate specialists and equipment.The main attention is paid to consideration of different types of antivibration supports. The correct choice of supports makes it possible to isolate the equipment from the action of internal (caused by the design of the machine tool and the cutting process itself) and external vibrations and to ensure both the accuracy of the relative location and movement of the machine units, as well as the reduction of the level of elastic movements and amplitudes of oscillations. The best option is the experimentally based recommendation of the manufacturing plant regarding the suitability of the selected supports, but it is valid for new machines tool, and even then, the operating conditions are not properly considered. The analysis of information sources showed that, despite the presence of dynamic studies, the necessary information is missing or quite outdated and generalized, which allows it to be used as an estimate, but not as final. The recommendations need to be updated accordingly and reconciled with the requirements for modern machines tool.
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.
