Abstract
An important feature in designing a truck’s cab is the driver’s comfort. Through cabin architecture it is intended to optimize its behaviour in all modes of operation of the vehicle.
Experimental studies to improve comfort parameters are laborious, require significant time and costs.
The study proposes and uses a model developed in the Simulink Matlab program, which takes into account the elastic system of the truck and the cabin suspension system. The simple model allows the changement of the input parameters - road parameters - and the variation of the elastic and damping characteristics of the cabin to improve the behaviour and comfort.
The results obtained by simulation are compared with experimental data. Suspension performance was analyzed for two type of road obstacle: a threshold and a step-down.
The study of the optimization of the cabin mounting system was achieved by modifying the values of the elastic characteristics and the damping in the model.
The model is also likely to be developed and used to study the dynamic behaviour of truck structures in different working regimes.
