Notes:
The current trend in automotive design is to optimize components for weight. To achievethis, automotive designers need to have complete understanding of various stresses prevalent indifferent areas of the component. The chassis frame assembly of a heavy truck used for longdistance goods hauling application is chosen for this investigation and dynamic stress-strainresponse of the component due to braking and cornering maneuvers are experimentally measuredand reported. A quasi-static approach that approximates the dynamic maneuvers into number ofsmall processes having static equilibriums is followed to carry out the numerical simulation,approximating the dynamic behavior of frame rail assembly during cornering and braking. With thehelp of commercial finite element package ANSYS, the quasi-static numerical simulations arecarried out and compared with experimental results. This study helps in understanding prevailingstresses in truck frame rails especially during cornering and braking maneuvers and brings out allgeometric locations that may be potential failure initiation locations. This study makes a case forfurther investigation on the effects of residual and assembly stresses on frame rails
