Chassis is used to denote the frame parts or main structure of vehicle, which is now, denotes the whole vehicle except body in case of heavy vehicles. The present study has analyzed the various literatures. After a careful analysis of various research studies conducted so for it has been found that there is the scope of optimizing different factors like weight, stress-strain values and deformation etc. by creating a slot in the chassis frame we can reduce the weight of the chassis.

... scribes the design and Structural analysis of the heavy vehicle chassis with constraints of maximum stress and deflection of chassis under maximum load. In the present work, the dimension of the Mercedes-Benz-Truck chassis is used for the structural analysis of the heavy vehicle chassis by considering "C" type section subjected to the Loading. A three dimensional solid Modeled in the CAE software CATIA and analyzed in ANSYS. The numerical results are validated with analytical calculation considering the stress distribution and deformation. After Validation, we create a slot in the Chassis frame to reduce the weight of the chassis frame. In Ansys software optimization of the slot is carried out.
