Year running 2019/20

Pre-requisite qualifications

Students enrolling on this module should have a good understanding of basic solid mechanics, including construction of free body diagrams, application of Newton’s laws of motion and simple stress analysis such as bending of beams. It would also be highly advantageous if they had previously studied mechanical vibration theory including multi degree–of-freedom systems, transmissibility, modal analysis etc.

Pre-requisites

MECH2610Engineering Mechanics
MECH2620Vibration and Control

This module is not approved as an Elective

Objectives

On completion of this module, students should be able to:
- describe the components and systems which are associated with a vehicle chassis structure;
- apply the principles of engineering science to the design and analysis of suspension and steering systems together with their components;
- state the fundamentals of acoustics and be able to apply these to the analysis and solution of chassis borne noise and vibration phenomena;
- categorise the various designs of chassis structure;
- illustrate the differences in chassis performance through application of appropriate analysis techniques.

Learning outcomes
On completion of this module, students should be able to:
1. Demonstrate in-depth knowledge and understanding of the main types of suspension systems used in automotive chassis engineering and how these affect vehicle performance.
2. Demonstrate in-depth knowledge and understanding of steering systems used in automotive vehicles and of the important parameters associated with these systems
3. Demonstrate in-depth knowledge and understanding of the different types of structures and materials used in automotive vehicles including consideration of safety under impact and long-term durability
4. Demonstrate an understanding of the important sources of noise, vibration and harshness (NVH) in automotive vehicles and be able to compare and apply different techniques to mitigate NVH issues
5. Demonstrate the ability to access a variety of sources in order to gain an in-depth knowledge of some important aspect of automotive chassis engineering not covered in the lecture course
6. Demonstrate the ability to reverse engineer the important parameters of a vehicle chassis from a limited and incomplete data set and to draw conclusions about the expected performance of the vehicle.
