Abstract

The research aim is to find out the most suitable cross section truck ladder chassis with the factors of maximum stress and equivalent stress. The vehicle's chassis is an important component, and static loading circumstances can lead to a variety of breakdowns. Unbalanced loading circumstances exist in the design of passenger and truck trucks; the local passenger bus's real carrying capacity for unloading is lower than that of the truck. The passenger truck chassis is designed with maximum stress and maximum deflection as the primary design parameters. But the present study focus is on the stresses developed in the chassis for each type of cross section. For our analysis the material we selected is ASTM 710 Steel. Different models of chassis have been selected with different types of cross sections that are I , C and rectangular (hollow). The solid modelling and Finite Element Analysis has been done in Ansys. In the end the analytical results are compared with the results of software.
