Go-Kart Chassis is the main supporting structure for Engine Mounting, Steering System, Wheels etc. It bears all the
stresses on the go – kart in both static and dynamic conditions. As there is no suspension system in the go-kart, huge vibrations
are produced by the shock due to direct contact of the wheel to the ground or from engine which is mounted on it. Due to this
Vibrational behaviour, Cyclic loads act on it and result in a fatigue failure. The purpose of this study was to analyse vibrational
behaviour of various materials and their mode shapes under natural frequency response. And to perform Impact Analysis for
evaluating withstanding capacity of the chassis under dynamic conditions. In this research the go-kart chassis is designed in 3DCAD modelling software CATIA V5 and finite element analysis is performed by using ANSYS 14.5 workbench on selected
materials. Hence, using modal and impact analysis defects are detected and necessary modification like change in materials,
geometry of stiffness.
