Truck maneuverability is one of the phenomena, which is considered in development stage of a commercial vehicle chassis structure. Torsional stiffness is one of the important properties of the chassis structure that significantly affects vehicle dynamic characteristics such as handling and rollover. The torsional stiffness is preferred to be as high as possible since lower torsional stiffness may cause resonance, vibration, poor handling, and rollover.Torsional stiffness can be improved through minor modification in the conventional ladder chassis frame.This paper presents the comparative study on improving the torsional stiffness of the chassis frame. The objective is to achieve the improved torsional stiffness by varying the neutral axis of the frame long member section at a desirable region. Torsional stiffness is dependent of the sectional modulus; this study provides an insight on increasing the torsional stiffness without addition of section modulus.
