| Summary: | 碩士 === 崑山科技大學 === 機械工程研究所 === 95 === Elliptical Motion Exerciser (EME) with adjustable link length has the functions of treadmill and stationary bicycle but can avoid direct impact on the joints of knees, ankles, and hips by cycling pedals forward and backward around an orbit.
According to the characteristics of elliptical motion exerciser, this objective of the study is to systematically design new rear crank type elliptical motion exerciser that can adjust its link length. First, this work provided the requirements and constraints of EME. Secondly, this work used the Yan’s creative mechanism design methodology to synthesis the feasible specialized kinematics chains and obtained satisfied rear crank type elliptical motion exerciser mechanisms. Thirdly, this work designed the rear crank type elliptical motion exerciser mechanism dimensions by referring the EME’s creatures. Finally, we developed a computer simulation program of the designed rear crank type elliptical motion exerciser mechanisms.
The results of this work are 97 new rear crank type elliptical motion exerciser mechanisms.
