Abstract

Dymola and Modelica have been used in research at KTH Vehicle Dynamics since 2000. With the introduction of new templates and standard components; Modelica has become increasingly accessible for researchers and students in the field of vehicle dynamics and therefore a project was initiated to evaluate its usefulness as an educational tool. The general idea is to introduce Dymola in smaller assignments; aiming to familiarise the students with the basic functions of the tool while demonstrating its use through simulation examples. Four exercises were studied: a truck braking system model; a friction disc clutch model; a controllable torque clutch model and a combined driver and vehicle model. The conclusions from this pilot study were that Dymola offers several ways to enhance the quality of vehicle engineering education; mainly due to the ease of modelling and the rich animation functions which make the simulation exercises more interesting.
