Description including Unit Aims

This unit is made up of two parts: CAD and Mechatronics

CAD:

This unit consists of lectures and design exercises in the computer labs. The lectures will teach the fundamental principles and techniques of CAD, describe how CAD is used in the design process and give an overview of automotive technology.

There will be two mini projects. One project will involve the design and analysis of a car wheel. A second project will involve the design of a steering and suspension assembly for a car.

Students will carry out the mini projects in supervised lab sessions. Students will produce coursework consisting of CAD drawings, engineering calculations and reports.

Mechatronics:

The unit will enable students to develop the skills to identify key design parameters, select suitable components from manufacturers' data, produce detailed designs from this information, and meet the needs of mechanical engineers with respect to electromechanical systems. This is achieved using specific examples of mechatronic systems in the automotive, manufacturing, robotics and biomedical industries. The unit also covers sensors, their interface with microprocessors, actuators and computer-based control. The unit also provides an introduction to engine design and performance analysis. The course is assessed by continuous assessment.

Aims:

CAD:

• To give the students basic competence in using a mechanical CAD package

• To give students experience in creative design

• To give an overview of mechanical automotive technology

• Prepare students for third year projects in terms of preparing drawings and designing test rigs

Mechatronics:

• Provide a foundation in motors, actuators, sensors and computer control required to carry out mechatronic engineering design tasks for automotive, aerospace and industrial automation applications.

• Provide a foundation in engine design and performance analysis.

• Broaden the students understanding of design process, and in particular the interfaces to other engineering disciplines with which they will need to interact as mechanical engineers.

• Increase student awareness of design practice in industry.

• Prepare students for 3rd and 4th year projects requiring the use of sensors, actuators and computer control.

Intended Learning Outcomes

CAD:

• Ability to create and present solid models of a wide range of mechanical parts and assemblies including structures and mechanisms

• A good understanding of CAD tools; such as assembly modelling and FEM.

• A good understanding of the main mechanical systems in automotive engineering

Mechatronics:

• Interpret manufacturers' data sheets and select suitable components for a particular task.

• Perform order of magnitude calculations and back of envelope calculations from first principles when tackling open-ended design tasks.

• Select an appropriate motor or actuation system and set of sensors for a given application, providing reasons for the choices made.

• Analyse overall system performance using both analytic methods and computer simulation.

• Develop a specification for an integrated electromechanical system that includes one or more actuators, sensors and computer control.

• Design and notate algorithms for control and data processing in mechatronic systems.

• Evaluate different solutions to a given requirement making use of graphical tools such as morphological charts and objective trees.

Teaching Information

CAD:

• 8 Lectures

• Computer labs: 10 x 2 hour supervised sessions

Mechatronics:

• 12 lectures on core subject material

• 1 seminar from external speaker from industry

• Design Labs: 8 * 3hour supervised sessions

Assessment Information

100% coursework

CAD

50% of coursework for CAD comprising 2 mini-projects (25% each). Students will write a report for each mini-project. Each mini project report will be up to 10 pages including text, diagrams and calculations.

Mechatronics

50% of coursework for Mechatronics comprising 3 design exercises Two design exercises (12.5% each) require the generation of a preliminary design for systems comprising actuators and sensors respectively. For each lab students prepare a short technical report typically up to 8 pages of text and diagrams.

The third design exercise is formulated and assessed in collaboration with industry (represented on Mechanical Engineerings Industrial Advisory Board), 25% is awarded for this exercise. Students prepare a technical report of up to 20 pages in length consisting of design calculations, engineering drawings, concept and schematic diagrams and text.
