摘要

In today's modern world, safety to driver and passengers is a major concern to every car manufacturer. For accomplishing this, new standards are being set for the safety of the occupant in different car scenarios like frontal head collision, side impact, rear impact and rollover. The automotive chassis is the main load carrier and energy absorbing component in all crash events. In the modern world, fuel consumption also constituted as a serious issue that has to be considered. Keeping all these constrains in consideration, a light and strong material should be used in chassis. In current work, chassis has been designed using computer aided design (CAD) programme Solid Works and was analyzed using a finite element analysis (FEA) programme ANSYS. The current research provides a standard finite element analysis procedure for designing off road vehicle chassis. A multi body dynamic crash analysis is an option to understand the exact behavior of the chassis for frontal and rear head collisions, to study the effect of speed of a vehicle. This report includes the creation of the safe design for dynamic impact analysis under different loading conditions (different pipe size and velocity).
