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.

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.

A long-term project at the Institute of automotive engineering at FME BUT, aims to analyze a motorcycle's dynamic riding behavior using in-house developed methods, originally intended for cars. A multi-body model of a motorcycle based on the measured parameters of a motorcycle and a system for measuring multiple physical quantities during a test ride were created. The necessary motorcycle parameters were measured using a 3D scanner and through experiments aided by computer technology and CAD software. Presented method is based on connecting measured data during test ride with an inverted multibody model. This enables the processing of data and analysis of measured dynamic states of motorcycle, while the details of output quantities are comparable with outputs from simulation calculations. Presented work has laid a foundation for a follow-up research and development work.
