Description

This unit is made up of two parts: CAD and Machine Design

CAD: This unit consists of lectures and design exercises in the computer labs. The lectures will teach the fundamental principles and techniques of CAD and describe how CAD is used in the design process. There will be two coursework projects. One project will involve the design of a bicycle wheel. A second project will involve the design of a steering and suspension assembly for a car. Students will carry out the projects in supervised lab sessions. Students will produce coursework consisting of reports and CAD drawings.

Machine Design: The unit will enable students to develop the skills needed to design machine systems incorporating machine elements. Machine elements will include standard components such as fasteners, gears, bearings, couplings and seals. There will be two design exercises, each requiring students to work in pairs. The first design exercise will require students to design a shaft assembly. The second design exercise will be more unconstrained and require students to iteratively design and simulate a car roof mechanism.

Aims:

CAD:

  • To give the students basic competence in using a 3D mechanical CAD package.
  • To give students experience in the three-dimensional packaging of mechanical systems using solid modelling.
  • To give an overview of bicycle technology.
  • To give students CAD skills necessary for third year projects.

Machine Design:

  • Provide foundation knowledge and skills in the selection and design of common machine elements such as fasteners, gears, bearings, couplings and 4-bar mechanisms.
  • Give experience in constrained and open-ended machine design.
  • Give experience in working collaboratively in design teams of two.
  • Give experience in following engineering processes to solve engineering design problems.
  • Increase student awareness of design information in the form of manufacturer’s data sheets and engineering standards.

Intended learning outcomes

CAD:

  • Ability to create and present solid models of a wide range of mechanical parts and assemblies
  • A good understanding of CAD capabilities such as assembly modelling and parametric design.
  • A good understanding of the main features in a car suspension system.

Machine design:

  • Ability to interpret manufacturers' data sheets and standards to select suitable components for a particular machine task.
  • Have a basic understanding of the different aspects of performance of common machine elements.
  • Ability to perform order of magnitude calculations from first principles when tackling open-ended machine design tasks.
  • Have an understanding of the different types of 4-bar mechanisms and their common applications
  • Ability to develop a specification for an open-ended design problem
  • Ability to create different concepts using design methods such as morphological charts and backwards design.
  • Evaluate different solutions to a given requirement making use of design methods such as weighted objecti
