Drivetrain development with SimulationX

 

Efficiency and dynamics of vehicle drivetrains are subjects to strict requirements. Rising cylinder pressures and supercharging of engines increase torque peaks and mean torques rise. Also, the drivetrain is subject torsional vibration excitations varying with engine speed. During his work as researcher at Volkswagen AG, which resulted in the PhD thesis „Active damping of torsional vibration in vehicle drivetrains“ Markus Neubauer developed a system for reducing torsional vibrations, which is independent of the engine order and is applicable to different operating modes.

 

The thesis shows the design of simulation models reflecting the dynamic effects of torsional vibrations in vehicle and introduces the system of an active torsional damper. The use of simulation tools such as SimulationX in the development is thereby of particular importance. The thesis considers the development process from the basics of the controller design, the task and objects of the controller, up to the system development and the test bench use. Markus Neubauer also presented his results at the ITI Symposium 2010 in a lecture entitled „Controller design for mechatronic applications of a drivetrain model built in SimulationX“.

SimulationX supports efficient modeling and analysis of powertrains as well as the simulation-based design of controlled drive systems. Its high functionality and code-export capabilities made SimulationX first choice in modeling and simulating the active torsional damper and its interaction with the complete drivetrain.
