Eligibility:

For single subject courses within Chalmers programmes the same eligibility requirements apply, as to the programme(s) that the course is part of.

Course specific prerequisites

The student requires knowledge of:
Statics (forces and moments, free body diagrams)
Kinematics (linear and angular motions)
Kinetics (planar motion of rigid bodies)
Linear algebra (solution of matrix equations)
Differential Equations (Solution of ordinary differential equations)

Successful completion of a Candidate Degree in Mechanical Engineering guarantees the students preparation for the course.

Aim

The course aims to take the student's existing knowledge of basic mechanics and apply them to road vehicles. The motions of the vehicle's centre of gravity will be analyzed in three independent analyses: longitudinal dynamics, lateral dynamics, and vertical dynamics. The vehicle systems relevant for its response in these directions will be introduced and described using first order differential equations. The student will be able to apply the concepts in the course to develop computer models that can describe the performance of each vehicle system independently.

Learning outcomes (after completion of the course the student should be able to)

Describe the forces acting between the tire and the road during the operation of a vehicle
Develop the first order mathematical models describing the longitudinal, lateral, and vertical dynamics of a vehicle
Implement analytical models into computer programs to describe the motions of a vehicle
Synthesize virtual prototypes of vehicle dynamics systems
Communicate concepts relevant for the performance, handling, and ride of a vehicle

Content

The course will begin with an introduction to the basic mathematical and mechanics concepts relevant for analyzing vehicle dynamics. The vehicle will be treated as a set of dynamic systems and detailed component analyses (ie kinematic analyses of suspension linkages) will not be undertaken. Four separate modules are used to describe the relevant systems and their analysis.
