The Modeling and Simulation of a Vehicle with Driver

In the thesis study that is named ‘The modeling and simulation of a vehicle with driver’, the effects are investigated that when vehicles are riding on a certain velocity, vibrations would be quickly transmitted to the passenger due to roughness of the road. For this purpose, the effects of the vibrations to the passenger are shown with comparing of the results of the thesis and the standarts ISO 2631 ve BS 6841 that are the standards of the effects of the vibrations to the human impact.

Vibration is one of the most important reason of the configuration of a vehicle. On one design, the great progress in driving performance of vehicles and methods of engineering changes to the structure has subjective. This phenomenon that can be named as ride vibrations is the reflection of these vibrations to the passengers. Vibrations can be transmitted to the passenger feeling by seat or the hands and feet of the passengers are often associated with ride vibrations. In this thesis, this ride vibrations are examined by simulating of the human model with quarter, half and full-vehicle model.

Actually, the quarter vehicle model can not help us to explain all the features of the vehicles. Therefore, in this thesis, due to the distance between the longitudinal axisof the vehicle, tremor and movement in the direction vertical leap in the field has been considered as a system with many input and a significant movement of many movements, pitch motion, could be taken into the consideration. At the same time not only analyzed in this thesis pitch, the bounce and radial vibration radial, and lateral traction forces, also drivers and seat are included in the model, modeling and simulation were made.

For this simulation model used in the literature on models and human models of vehicles have been selected. In this way, driver and seat are included to full-vehicle model with seven degrees of freedom. As a result, the system model with 17 degrees of freedom is derived and simulated. The effects of the vibrations to the human impact are shown with comparing of the results of the thesis and the standarts.
