Abstract
With the continuous development of rehabilitation medicine, the design and optimization of lower limb rehabilitation equipment has become an important research field. Based on ANSYS software, this paper conducts a comprehensive study on the structural design, material selection, simulation and calculation of lower limb rehabilitation equipment, aiming to achieve the safe, easy to use and effective goal for patients.
This paper aims to conduct a comprehensive structural design, material selection, simulation calculation and optimization of lower limb rehabilitation equipment based on ANSYS software. First, according to the functional requirements of the equipment. Secondly, ANSYS was used to simulate the equipment strength and stiffness to ensure the stable performance of the equipment in different situations. In addition, this paper focuses on the mobile mechanism design and wheel selection to ensure the mobile performance of the device. At the same time, the safety protection mechanism of the equipment has been carefully designed and the strength and stiffness simulation. In part assembly and connection, this paper emphasizes high precision and reliability. Finally, the appearance color selection of the device and the accessibility of the device fully consider the patient experience. Through SolidWorks for structural modeling, combined with the standards of China Standard Information Network and component selection, the equipment has reached the high standard in the design stage.
Key words: lower limb rehabilitation equipment; structural design; ANSYS simulation; material selection; mobile mechanism design;
