Abstract:
A chassis houses various key components such as the power-train, suspension system and the bodywork of an
automobile. Thus, the chassis must be robust enough to absorb the static and dynamic forces generated by these
components to assure safety and superior rideability of an automobile. In this work, efforts were made to improve the static
and dynamic characteristic of a Go-kart chassis by using the modal analysis. The results of the modal analysis were
carefully examined and the members are geometrically modified on the basis of excessive deformation. At the termination
of the of this analysis, it was observed that geometrical modification has not only improved the dynamic characteristic by
17.5% but also shown improvement in the stiffness and crashworthiness of the chassis.
