‘Learning while Earning’ Short distance-learning courses for industry professionals
Motorsport Chassis Dynamics A Motorsport Knowledge Exchange programme
A distance learning course which will provide you with an excellent understanding of the theoretical and practical issues involved in designing suspension systems for race cars
Motorsport Engineering Centre
Introduction Motorsport Chassis Dynamics is offered in two parts. Students are able to either take both parts as a whole course or each part individually. While Parts One and Two are stand-alone units, if you intend to study the whole course, it is advisable to complete the courses in chronological order.
What are the courses about? Motorsport Chassis Dynamics is predominantly about the dynamics of a racing car – the non-equilibrium accelerating conditions which accompany the car as it progresses around the lap of a motor racing circuit. The object of the exercise is to save time all around the lap, and the racing car does this by maximising its accelerations: forwards from the start and along the straights; rearwards ‘deceleration’ (negative acceleration) under braking; and lateral accelerations when cornering. Any other conditions are simply wasting time. These non-equilibrium acceleration conditions are embraced by the field of dynamics – the study of accelerations of objects and the forces required to produce them, or – vice versa – the study of forces acting on bodies resulting from accelerations they are experiencing. To achieve the very best performance boils down to one key philosophy – aiming to make sure that whatever the racing car is doing, and wherever it is on the circuit, its tyres are working to their maximum potential. The tyres are the crucial parameter, or specifically, the interaction between the tyres and track surface is the crucial parameter. Everything happens through these four contact patches – accelerating, braking, cornering, and standing still even. The race car and its suspension systems have to be designed so as to maximise the grip available from the tyres for all the conditions we’ve outlined. This provides the best tool for the racing driver to then go racing.
Who are the courses for? The courses are designed for engineers having a mechanical and/or automotive/motorsports background, probably with a BSc or BENg degree, although it would be applicable for those with practical racing experience and sufficient mathematical knowledge. Motorsport Chassis Dynamics (1) and (2) are postgraduate level courses and will require on average 400 hours of study each to complete
Benefits of the course • Developed WITH industry FOR industry • User- and industry-friendly course delivery mechanisms • Runs 24/7, meaning that students can begin the course on any day of the year • Flexible, supported distance learning format allows engagement by work-based learners • Provides a highly comprehensive range of material, including case studies drawn from real race teams
• Throughout the courses’ development, the motorsports industry, at a number of levels, has informed the curriculum, and provided strategic steer and critical review of developed material • A number of different formats to suit different learner needs

How do the courses work? The courses are studied part-time via distance learning and should take about 12 months each to complete although there are no formal start- and end-dates. The course materials comprise: • The Course Study Guide booklet, which contains various instructions and background details; • A series of printed Course Workbooks, which contain the main reading material, as well as a number of activities which need to be completed satisfactorily for course progression; • A DVD supports the main text and contains working Case Studies detailing some of the processes involved in operating racecars successfully. Material is drawn from real race teams, including F1; • Access to the ‘Brookes Virtual’ virtual learning system at Oxford Brookes University, which can be used for a number of purposes, including to answer course questions, to provide online discussion forums, to access reference material, and to communicate with course tutors etc.; • Loose-printed articles from specialist journals giving useful background and illustrated examples • Remote access to the MSC ADAMS software application (and ChassisSim, if you study Part 2); • A final project, which forms the first of the two main assessable components of the courses. The core content of the course is supported by computer exercises, experiments, and simulations. You will be expected to study autonomously, although you will be able to contact a personal tutor. A number of selftest quizzes are included throughout the course. An end-of-course exam provides course assessment. Learners can supplement the theoretical content of the course with attendance at an additional, optional ‘boot-camp’ style residential practical course which runs over a period of five days. During this session, subject specialists will provide in-depth knowledge and hands-on examples.
Course Requirements You will need a computer running Windows XP or higher, with a DVD drive to access the course material. You will also need access to the Internet to use online resources. The course makes extensive use of the ADAMS computer simulation software. You will access a remote copy of the software via the Internet. It is NOT necessary to know how to use ADAMS before you start the course. Full instructions will be given.
Tuition Fees The tuition fees* for the courses are £2400 and £2800 respectively, although modules are available as standalones and cost £1200 each. If both parts of the course are taken there will be a discount of £500**. The practical element of the course is an additional £8,000. The examination can be taken at this time.
What industry is saying about the course ‘Well written & very informative. The basic ‘philosophy’ of Pat [Symonds] shows through which I think is really important and one of the best values you have. He adds practicality to the course which counts for a lot.’ Mark Preston, Technical Director, Formtech Composites, former Technical Director, Super Aguri F1
‘‘I was very impressed by the quality of the course. I liked the layout and it is very easy for the reader as
there was a good balance of equations, physical explanations, and useful figures. The amount of work is very impressive.’ Thomas Wissart, former R&D Engineer in charge of tyre data analysis, Super Aguri F1
‘This course will probably become the reference for many people’. Ben Michell, Senior Design Engineer-Car, Dunlop Motorsport
