초록
There have been many attempts to make kart chassis domestically to lower the price of complete kart. However nobody made a successful chassis due to the lack of understanding the characteristics of kart chassis frame. In this work, a baseline chassis frame under the bending and torsional load is studied. Design target is that the baseline chassis frame is quite adequate not only for the beginners but also for the beginning racers. Results from the analysis are used as a guide to design or modify the baseline chassis with the goal of proper torsional stiffness. Minimum increase in weight is being forced. As a result, the baseline chassis frame was designed, made, and tested. Based on the design results, complete karts are being manufactured by the small 1 size domestic company and these karts are being sold and run in the market.
