This task is firstly find the advantage and disadvantage of the treadmill and then fulfill the design of the multifunctional treadmill. The main function of the folding design features can be folded up when not in use to save display space;Manual adjustment of slope feature allows users to run different slope can experience the feeling of running; auto-tuning function can change the speed of the user running along with changes, which allows users to run and so on treadmill followed.Also the design of multi-running machine to facilitate handling, structural profiles, exterior appearance, humanity design. In addition to running features, there are US-waist, wriggled, sit-ups, dumbbell, fitness back and neck massage vibration mode for the user to choose. This design strength calculation after the first estimate was corrected, by a lot of calculation and verification, design not only strong, beautiful and simple and reasonable structure of the internal drive and external base frame design, and multi-functional design of the structure to do a certain design. And draw an important component of CAD map. Then make out a more comprehensive，practical and cersatile treadmill design.
