ABSTRACT

This paper describes the use of multibody systems analysis for the modelling and simulation of a vehicle towing operation. The work carried out was used to demonstrate the use of software to predict typical in service dynamic loads which were then used as inputs to a finite element stress analysis. Dynamic simulations were carried out to represent driving on flat or inclined road surfaces and the effects of road bumps and potholes. The results of these studies were used to predict the peak longitudinal and vertical components of load acting on the tow hitch. An overview is provided of the ADAMS® dynamic analysis program chosen to perform the simulations and the modelling elements used to represent the system under consideration. The use of finite element stress models is well established and is not discussed here.
