## Course information

### Content and learning outcomes

#### Course contents *

Vehicle dynamic characteristics. Coordinate systems and coordinate transformations. Comfort, handling, rollover. Modelling and derivation of equations of motion for vehicles driving straight ahead and during cornering. Force and road excitation. Stationary and non stationary driving. Frequency responses. Elastic elements of the wheel suspension, effective cornering stiffness, roll steer. Handling diagram. Nonlinear components and non dimensional equations of motion. Vehicle combinations and stability. Statistical methods.

#### Intended learning outcomes *

The over all goal of the course is to give the student a deeper knowledge about modelling, simulation, measurement and analysis of ground vehicles dynamic behaviour

Students graduating from the course should be able to:

• describe the basic terms within vehicle dynamics
• describe and use the coordinate transformations necessary for vehicle dynamic analysis
• create simple models of vehicles for dynamic analysis
• explain the assumptions/limitations of the created models
• derive the equations of motion for vehicles in order to perform an analysis of the bounce and pitch motions that arise due to for example acceleration, braking and uneven road surfaces
• derive the equations of motion for a vehicle during stationary and non-stationary cornering and to analyse the vehicle directional stability and roll behaviour
• derive the effective cornering stiffness when considering the elastic elements in the wheel suspension and be able to analyse it’s effect on the dynamic characteristics of the vehicle
• derive the equations of motion for a vehicle combinations and analyse it’s stability in the yaw direction
• create handling diagrams and draw conclusions from them
• create, performe and analyse a simple test plan for vehicle dynamic analysis by using statistical methods
• explain how different changes of the construction of the vehicle affects the dynamical characteristics of a vehicle.
• plan, carry out, evaluate and present a simple field test for vehicle dynamic analysis.
• apply the gained knowledge on practical problems.
