        A kart is a vehicle without the suspension system and the differential gear. The kart frame as an elastic body plays the role of a spring. By the cornering of a kart, rolling, pitching and twisting motions are induced in the kart frame. Also the slip or noncontact of the wheel and a permanent deformation of the kart frame can be induced. In order to examine closely this phenomenon of the twisting deformation, measurement and analysis on torsion working stress with strain gage and tracking system are needed. According to the measurement result, while steady state driving in a curve in general the torsion working stress of the kart frame will be increased depending on the vehicle velocity, but the kart frame will be not permanent deformed. However, analysis of the torsion working stress in comparison with torsion fatigue limit shows that while unsteady state driving as clash with same drive condition the racing kart frame will be deformed more quickly as the leisure kart frame.

        A kart is a vehicle without the suspension system and the differential gear. The kart frame as an elastic body plays the role of a spring. By the cornering of a kart, rolling, pitching and twisting motions are induced in the kart frame. Also the slip or noncontact of the wheel and a permanent deformation of the kart frame can be induced. In order to examine closely this phenomenon, measurement on height-displacements with various sensors and tracking system and analysis on the kart frame twisting characteristics with the rolling and pitching angle are needed. According to the measurement result, while driving in a curve at high speed the kart frame is quite twisted. Analysis on the measurement results shows that a kart used primarily in high speed requires a frame with low torsional stiffness and a frame material with high tensile strength and large elongation.
