Heavy commercial vehicle yaw control simulation
Jan Fojtášek
JVE International Ltd.
The aim of this article is to present universal multibody dynamic model of the heavy commercial vehicle equipped with direct yaw moment control system. The presented simulation method is based on interconnection of the multibody software ADAMS and the graphical programming environment MATLAB Simulink. The main task is to demonstrate the potential effects of the direct yaw moment control using an active differential by heavy commercial vehicle with rear wheel drive.


Complex approach to computations and analysis of vehicle dynamics
Petr Porteš, Lubor Zháňal, and Jan Fojtášek
JVE International Ltd.
The goal of this article is to present a method for vehicle dynamics development based on multibody system approach in combination with real vehicle testing and data analysis. Described technique consists of two multibody models with the same level of complexity. First direct multibody model of the complete vehicle is suitable mainly for sensitivity analysis. The other inverse multibody model is used for real vehicle dynamic states reconstruction from measured data. Results of these two models are then post-processed and visualized together in a custom-made data analysis software.
