| Course code : | ME-VED-U1 | ||
| ECTS Credits : | 5 | Status : | Optional |
| Revised : | 16/12 2009 | Written : | 16/12 2009 |
| Placement : | 6. semester | Hours per week : | 4 |
| Length : | 1 semester | Teaching Language : | English |
| Objective : | To provide the students with the fundamentals of vehicle dynamics. Furthermore, the course forms the basis for further study of vehicle design and automotive engineering. A student who has met the objectives of the course will be able to: • Understand various tire models and their limitations. • Determine under steer gradient. • Determine roll steer, lateral load transfer and rollover. • Determine brake forces distributions. • Understand the basic concepts of stability and control. • Understand the basic demands to the handling of a vehicle. • Read literature on vehicle dynamics and automotive engineering. |
||
| Principal Content : | The emphasis of the course is on the analysis and evaluation of the performance of cars and trucks Students will build and numerically integrate the Equations of Motion for their own vehicle models following a crawl-walk-run principle. Their models will by the end of the course be capable of simulating limit maneuvers including combined braking and turning. Fundamental as well as advanced vehicle dynamics terminology will be introduced such as Under steer Gradient, Characteristic versus Critical Speed, Roll Center, Roll Stiffness Distribution and different tire models and their limitations with respect to real tire performance. Furthermore, the course will cover the mathematics behind the stability of their derived vehicle dynamic systems. Skills needed in basic dynamics, basic ordinary differential equations, and the ability to integrate differential equations numerically. The students will be introduced to an advanced dynamics simulation software for use in class assignments as well as other projects the students might have involving dynamics. |
||
| Teaching method : | The teaching is based on "learning by doing". There will be introductory and summing up lectures. Project work in small groups includes tutorial exercises, assignments, and computer simulations. | ||
| Required prequisites : | Applied Mathematics 1 (ME-MAT1) and Applied Mechanics 2 (ME-MEC2) or equivalent. | ||
| Recommended prerequisites : | Control Engineering (ME-CEN). | ||
| Relations : | The course methods can be used in many courses and projects, such as the Bachelor project. | ||
| Type of examination : | Look under remarks | ||
| External examiner : | Internal | ||
| Marking : | 7 step scale | ||
| Remarks : | Oral examination based on a number of course assignments and a group report. The final evaluation of each student will be based on an assessment of the presentation of the course assignments and the group report. This is a relevant optional course in the study program “Engineering Design & Industrial Innovation” offered by the Department of Mechanical Engineering. It is, however, a methodological course for engineering students, specializing in automotive engineering and transportation. |
