Vehicle Dynamics (7.5 ECTS)

Vehicles are of main importance for the logistics within the society. Vehicles are being used to transport products and people but also at different kind of construction work etc. The demands on these vehicles are high not at least regarding dynamical properties as comfort.

The course starts of with analyses on simple rigid body dynamical models where properties like eigenfrequencies, eigenvectors, critical damping, transient solution and steady state solution are explained. After the basic concepts of rigid body dynamics have been discussed, more specific vehicle dynamical models are investigated. With these models stability properties such as over steering, magnification of acceleration roll etc. are analysed. Hence, a number of analytical expressions are derived which can be used when designing vehicles. Other concepts that are discussed in this course are Ackermann camber, caster, toe and Steering axis inclination.

Drive trains are further analysed within this course in vehicle dynamics. One important subject in this part is how to design a gearbox for certain performance where torsional vibration is one important criterion for dimensioning.

After completed course, you are supposed to be able to:

  • Understand and explain fundamental concepts within vehicle dynamic
  • Use existing CAE-tools for design situations
  • Interpret different kinds of dynamical result both from simulations as well as from measurements
  • suggest suitable measures for how to handle vibration problems in vehicles
