Abstract: The torsional behaviour of commercial vehicle frames is dominated by warping torsion, because warping is inhibited in the joints where the cross-members are attached to the side-members. This paper presents a hybrid method of analysis, which combines finite element idealization of the joint areas with analytically derived beam elements for the cross-members and side-member sections. The beam element includes warping torsion force-displacement relationships. Thus, the flexibility of the joints is included together with the compatibility of warping displacements. The method gives close agreement with experimental results.

Keywords: vehicle frames; warping torsion; structural analysis; finite element analysis; FEA; nodal substructures; flexible joints; cross-section deformation; vehicle design.
