The experts believe the race apparatus market will take high price products as the leading factor in the future. Low price products sell too good, price in recent years had the tendency to rise. Pay attention to consumers with fashionable life and think the price of the race apparatus is the natural thing above 1000 . dollars. These signs indicate , the race apparatus will still increase continuously in the future. Have used the threedimensional entity software SOLIDWORKS to carry on the entity modeling of the part in the course of designing, design with the ensemble architecture . Design and include the support , the base shelf , the cylinder , run board, is it bring to run, design consult domestic and international every brand structure and design, carry on accurate calculation by anization to transmission, and design stress shock attenuation systematic importance and run the static proof functionality of the board especially, the design enables persons who run to experience the strength of the race apparatus. Because of the particularity of the race apparatus, safe problem is worth paying close attention toer, how to use the race apparatus correctly, it is as important as maintenance of the race apparatus.
