 WB3404A: Vehicle Dynamics A ECTS: 3 Responsible Instructor: prof.dr.ir. E.G.M. Holweg Instructor: dr.ir. M. Corno, Ir. S.M.A.A. Kerst, A. Kunnappillil Madhusudhanan, Ir. E.J.H. de Vries Contact Hours / Week x/x/x/x: 0/4/0/0 Education Period: 2 Start Education: 2 Exam Period: Exam by appointment Course Language: English Course Contents: Basic elements of the dynamics of road vehicles (car, truck, motorcycle). Ride vibration response to road unevenness. Sine and stochastic roadprofile. Single, two and three mass/spring/damper systems. Linear and non-linear models. Vibrational modes and stability. Discomfort analysis. System identification. Roadholding: vehicle handling and stability. Response to stear input and side wind. Singel two-wheel vehicle model to discuss effects of tyres, inertia and geometry. Influence of several design variables: steering and wheel suspension, kinematics and compliance, toe angle, camber, roll axis, roll stabilizer, load transfer. Motorcycle stability and modal shapes (brief discussion of results) Study Goals: The student is able to apply dynamics methods and knowledge on vehicle specific problemsMore specifically, the student must be able to:1. quantify comfort and road holding: recognise the paradox for optimal suspension design2. realize that linear models are approximations of reality in many aspects3. employ single mass and higher order models for vertical vibration analysis, and justify the choice for single d.o.f., quarter car or half car model4. implement the most common non linear elements in vehicle(models) and discover some analytical solution methods5. solve non-Linear problems with numerical integration routines6. apply Lagrange method to derive equations of motion7. analyze driving stability in the horizontal plane using Hurwitz criterion8. characterize vehicle handling in terms of under- and oversteer, apply critical and characteristic velocity on the vehicle behaviour9. derive the single track model, linear and including elementary non-linear properties Education Method: Lectures (4 hours per week), practical exercises Computer Use: In working out the problems the computer will be helpful, for some problems essential. MatLab will be used for analysis and simulation Literature and Study Materials: Course material:Lecture notes: Vehicle Dynamics A (pdf on blackboard)References from literature:Mitschke, Dynamik der Kraftfahrzeuge Gillespie, Fundamentals of vehicle dynamics 1992Genta, Motor Vehicle Dynamics 1997, 2003, 2006Pacejka, Tyre and Vehicle Dynamics 2002, 2006 (2nd) Assessment: Oral exam, by appointment Remarks: Laboratory project(s):About 7 problems (exercises) are requested to prepare at home.
