Behörighet:
För kurser inom Chalmers utbildningsprogram gäller samma behörighetskrav som till de(t) program kursen ingår i.
Kursspecifika förkunskaper
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 Bachelor Degree in Mechanical Engineering guarantees the students preparation for the course.
Syfte
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.
Lärandemål (efter fullgjord kurs ska studenten kunna)
The student will have developed the following competencies after the successful completion of the course 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
Innehåll
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. Introduction/Preliminaries: Mathematic and Mechanical Notations Module 1: Tire Tire forces/moments Tire Construction / Tire Types Rolling resistance Longitudinal slip Lateral slip Combined slip Simple tire models Module 2: Longitudinal Dynamics (Acceleration/Braking Performance) Wheel torque applied to road: Single tire car model Braking and acceleration: 2 axle vehicle model (load shift) Braking and acceleration: 2 axle vehicle model (load shift and vehicle pitch) Module 3: Lateral Dynamics (Handling) Low speed Ackermann Steering Bicycle model High speed steady state turning Transient steering Lateral load transfer Stability analysis Module 4: Vertical Dynamics (Ride) Road roughness representation Suspension components (springs and dampers) 1 and 2 Degree of freedom Quarter car model Bounce Pitch Model
Organisation
The course includes formal lectures, computer laboratories and tutorial sessions.
Litteratur
Extended lecture notes.
Examination
A final written examination will comprise 50% of the course grade. Submitted assignments in the course will make up the remainder of the grade.
