Mechanical Innovation Design And Finite Element Optimization Analysis For The Multifunctional Interactive Fitness Bike

As the quality of life is rising constantly, the fitness industry has developed quickly, and the innovation and development of fitness equipment has been also in high demand. At present, the industry of fitness bike has been doing the research and development mainly in the field of comfort and safety. But the mode of motion hasn't been got the breakthrough development. The trainer will be tedious in the exercise and the effect will be reduced.Therefore, a new type interactive fitness bike is introduced in this research. The special place of this fitness bike is it can be driven by either hands or legs, or any combination of any hand and leg as the user likes. By changing the riding mode, the user can do many different exercises such as stair-climbing, jaguar-like running, and so on, as well as cycling. Various exercise modes with the reasonable training procedures can greatly promote the interest and exercise effect of the fitness bike.In this paper, the research is mainly about the mechanical innovation design and relevant analysis of this new type fitness bike. Firstly, in order to meet the comfortable requirement for the exercise modes, the comprehensive and reasonable ergonomical design and analysis for the major structure size of fitness bike is completed to unify the novelty, comfort and safety. Secondly, basing on ergonomical design, the new motion modes and general structure scheme are systematically analyzed, and according to the relevant functional requirement, the mechanical design for all key components are mainly analyzed. Then, the parts of the resistance system such as the resistance output, structure and so on are analyzed comprehensively. For the unique driving mode of this fitness bike, one new resistance automatic adjustment system is designed to make the trainer also obtain steady and comfort exercise feeling in new mode of motion. And based on the experimental analysis to the model, the feasibility of scheme design is verified. Finally, for the problem of synchronous belt slipping during the experiment, the finite element optimization analysis to the extension board of stander is completed based on the software ANSYS Workbench to achieve the desired the requirements of the performance and industrialization.
