Research and Development of an Adjustable Elliptical Exerciser
This paper presents a novel design of adjustable elliptical exerciser, which can adjust both stride and inclined angle. Firstly, we use a selected coupler curve of four-bar linkage to design a six-bar linkage. From the six-bar linkage, we investigate the parameters which affect the corresponding elliptical path and its inclined angle. By considering the way of adjusting the inclined angle, the final design becomes a 2-DOF seven-bar-eight-joint linkage. We use SolidWorks software to design this novel elliptical exerciser, and use CAE software to check the stresses and strains to ensure the strength of the members of this design. The prototype of this novel design of adjustable elliptical exerciser has been fabricated, and its feasibility has been confirmed.
