Abstract: This paper describes a computer-based modelling, simulation, and validation effort to aid in the development, testing, and design improvement of a prototype car-carrier structure. In this research, a finite-element model of a prototype car-carrier structure was developed and numerical computations were conducted using LS-DYNA to investigate the stress/strain distribution within the carrier structure when negotiating a typical speed bump. The model was compared with experimental results taken from tests using a truck car-carrier of similar configuration to the trailer investigated in this research. Local and global geometric modifications were made to minimise lateral structural deflections and stress and strain concentrations.

Keywords: car-carrier; deflection; fatigue; field test; finite element; stress/strain concentration; structural modifications.
