| Abstract: | A design scheme of body-building machine for leg and back was contrived. Its principle,parts and drive system was introduced,and kinematics and dynamics analysis on its crank-slider mechanism was carried out. On the basis of considering dynamic loads,strength check on the main axis and stability check on the link were made separately. The results suggest that the scheme meets the conditions of strength and stability. Finally,a prototype was produced according to the scheme. After using the prototype,it has ... |
