The integration of larger combination vehicles into the existing infrastructure using heavy vehicle simulation

The integration of larger 'innovative' vehicle combinations into the existi ng infrastructure relies heavily on proving the concept to government and l ocal authorities. Simulation modelling has proved to be a useful tool in sh owing that an innovative vehicle is a safer and more efficient alternative to conventional equipment. This paper will provide examples of the use of A UTOSIM(TM) in developing custom yaw/roll and yaw/roll/pitch models for inve stigating the dynamic performance of combination vehicles. Models will be d escribed for large innovative road trains. Consideration will be given to t he modelling of the trailing fidelity of these vehicles on non-planar surfa ces, and examples of model outputs for combination vehicles operating on va rious three-dimensional features will be given. Examples of the application of dynamic performance standards related to stability and control in a num ber of performance attributes will be considered, and the performance of so me innovative vehicle combinations will be compared with that of currently- operating conventional trucks.
