- to underpin and extend the theoretical concepts and design criteria related to three dimensional stress/strain analysis including the definition of load paths under normal driving conditions of automobile structural components, sub-assemblies and assemblies.
- To extend students' knowledge in vehicle engineering and its road dynamics so that confidence can be built up in the application of advanced mechanics theories to real mobile structural problems.
- To provide typical industrial problems that need solutions for the design of that perfect vehicle, which is structurally sound with long life cycle and as a result provides comfort to occupants.
- Types of vehicle body structures and their evolution
- Vehicle structural component integrated design: Beams (straight & curved), struts, flat rectangular & corrugated plates.
-Vehicle structural component analysis: Analytical - The Rayleigh-Ritz method for beams, The Bredt-Batho Theory for vehicle chassis frames, The Castigliano method used in energy theory for geometrically complex vehicle components and sub-assemblies.
- Vehicle overall structural design: ANALYTICAL- modelling of car body in two- and three-dimension. The use of the Simple Structural Surface Method (SSS) for vehicle structures as employed in industry. FINITE ELEMENT (FE) - modelling of the entire car body using HYPER-MESH & LS-DYNA codes.
- Vehicle Dynamics: General rule and mechanics of road loads transfer into the car body. Analysis of load path through tyres (handling), suspension system (ride) and the definition of car propensity to roll (roll).
The delivery of this module will concentrate on promoting problem solving skills using analytical and numerical tools that may include car manufacturers' software.
The delivery will be structured as follows:
-Long and Thin - Semesters I & II
- Formal lectures 20%
- Tutorials 10%
- Laboratory sessions/report 7%
- Self direct learning 60%
when you have successfully completed this module you will:
to demonstrate that you have achieved the learning outcome you will:
|1.||Apply appropriate engineering science methods in verifying both software and experimental results.||Correctly, analytically calculate 3D stress/strain values and compare these with those obtained through the use of software and experiment.|
|2.||Carry out appropriate experimental and theoretical techniques to assess the suitability of automobile structural body components and sub-assemblies in relation to failure and damage.||Correctly evaluate the difference between closed form and approximate solution and reflection on how the difference add its effect can be minimised.|
|3.||Employ industry standards in design of vehicle body structures.||Use industry computer packages, European and American standards on vehicle safety in the design of new vehicle body structures.|
|4.||Appraise a problem by developing an appropriate model.||Select the appropriate techniques and justify the achieved solution.|
|5.||Model structural components, sub-assemblies and assemblies in order to simplify otherwise complex problems into say Simple Structural Surface (SSS) or Shear Panel Method (SPM)||Appraise a problem by developing an appropriate model.|
|6.||Develop knowledge and understanding of the method of dynamic analysis applicable to modern road vehicles||Perform analysis of various dynamic models to obtain accelerations and forces, natural frequency and relate these to the desirable attributes of modern road vehicle.|
|7.||Apply mathematical skills to a range of dynamic problems associated with vehicle behaviour and how it introduces forces into the vehicle body.||Construct dynamic models and solve them using Newton’s Laws and other appropriate methods. This should include good understanding in the interpretation of the dynamic modelling in terms of actual behaviour of a car.|
|8.||Apply analytical and interpretive skills to the analysis of a vehicle’s performance, ride and handling.||Apply mathematical techniques to analyse a vehicle’s performance, ride and handling characteristics and to interpret the results in terms of satisfactory or unsatisfactory behaviour.|
