1 EIDGENOSSISCHE TECHNISCHE HOCHSCHULE (ETH) SWISS FEDERAL INTITUTE OF TECHNOLOGY, ZURICH INSTITUTE FOR DYNAMC SYSTEMS AND CONTROL Department of Mechanical and Process Engineering VEHICLE DYNAMICS AND DESIGN Spring Semester 2010 SYLLABUS DESCRIPTION: The course will present students with the opportunity to learn the basic theoretical principles in Vehicle Dynamics and Design combined with a practical approach-using computer aided techniques that will allow students to build and analyze vehicle dynamics and mechatronics systems used in vehicles using computer models for analysis and design. The course will cover a variety of topics such as study of tires, drive train and gear boxes in ground vehicles. Kinematics of linkages for analysis of position, velocity and acceleration in two and three dimensions with applications to mechanisms, suspensions and steering mechanisms. Vehicle Dynamics using multibody systems in three dimensions. Computer models of vehicles using solid models and dynamic models. Use of computer simulation techniques for multibodies and multi energy systems consisting of vehicle electromechanical and hydraulic systems. Computer models and simulation of vehicle collisions and rollovers, failure analysis, finite element models (FEA). INSTRUCTOR: Prof. Dr. José J. Granda Office: ETH Zurich, ML K grandajj@ecs.csus.edu Or jose.granda@idsc.mavt.ethz.ch OFFICE HOURS: Wednesdays 1:00 2:00 pm. or by appointment TIME and PLACE: 10:00-12:00 p.m. Lecture ML H43 14:00-16:00 p.m. Exercises ML K31 OBJECTIVES: The course will provide the student with analytical and computer skills that will allow students to analyze and design two and three dimensional components and entire working assemblies. Train students so that they can acquire the ability to perform kinematic and kinetic dynamic analysis, Finite Element Analysis, time and frequency domain simulations of dynamics systems used in vehicles.

CLASS NOTES: Students are responsible to take their own notes. The student should not rely only on class notes but rather your are expected to study independently the assigned reading assignments and homework following the schedule. Students are responsible for ALL material presented in class. This includes any announcements, changes or clarifications made in class as well as the due dates. KNOWLEDGE, SKILLS TO BE GAINED FROM THIS COURSE Analytical and computer skills that will allow students to: 1) Understand the behaviour of vehicle systems and subsystems, tires, drive train, gear boxes 2) Understand vehicle dynamics for use in design and performance of ground vehicles. 3) Use analysis and techniques learned in solid modeling and basic dynamics to develop computer models of linkages and complete working assemblies in two and three dimensions. 4) Transform solid models into models of vehicles for analysis of kinematics, (velocities and accelerations), kinetics (forces and moments). 5) Perform simulations of rigid multi-body assemblies and calculation of loads, dynamic forces, energy and momentum in two and three dimensions. 6) Vehicle parts and assemblies under impulsive impact forces and collisions. Simulations using dynamic Finite Element Analysis under dynamic loads. 7) Study of electromechanical and hydraulic systems used on vehicles applying multi energy simulation methodologies such as Bond Graph modeling 8) Apply the concepts of vibrations to the design of vehicles.

3 COMPUTER USAGE: Computers are used for writing reports (WORD) and presentations (PowerPoint). Spreadsheets are used as appropriate in doing multiple trade studies. Computational tools such: SOLIDWORKS (Three Dimensional solid modeling), WORKING MODEL 2D (Mechanisms dynamic analysis), NASTRAN4D (Three dimensional multibody analysis and design), ADAMS (Vehicle design software), CAMPG (Computer Modeling Program for Dynamic Systems), MATLAB (Simulation in time and frequency domain, state space models, transfer factions, SIMULINK (Block Diagrams, control). COURSE GRADING: Quizzes/Exams... 40% Homework Assignments... 10% Computer assignments... 30% Term Vehicle Design Project.. 10% Final Exam... 10% 100% Exams and assignments will be graded balancing the procedure used and the correctness of your answer on an equal basis. Presentation and organization of your assignments will also be considered in grading. There will be Quizzes approximately one to two weeks apart, including the last week of class. Quizzes and final exam will be closed book exams. HOMEWORK, COMPUTER ASSIGNMENTS: Reading and/or homework assignments will be assigned every week establishing due dates. When not specifically specified, assignments will be due in one week after assigned. EXAMINATIONS: There will be quizzes and exams. These will be announced to cover specific topics of the course. The final exam will be administered in accordance with the University scheduled time..
