Paper Description

Edit Paper Description Content

This paper builds on knowledge of the design process of Engineering Design (ENGG282), Mechanics of Materials (ENMP213). The benefits and pitfalls of simulating mechanical designs is demonstrated and discussed. Important mechanical engineering machine elements are covered; gears, gearboxes, belts, chains, friction devices, motors/machine and compounding of mechanisms such as winches, screw thread, hydraulics, levers. Selection of bearings and springs and tolerancing is covered. Electrical machines are explained in a mechanical engineering context including; DC, AC motors and solenoids. Engineering drawing is taught in workshops. Health and safety issues for mechanical engineers is explained. A large component of this paper is a group design project that requires the design, manufacture and testing of a machine to meet a design brief and specification. Project management will be taught to help with groups with the design project.

Paper Structure

Edit Paper Structure Content
This paper is taught with three lectures, one tutorial and a two hour workshop each week. Students work in groups of four to complete a Project Based Learning (PBL) design assignment. The assignment enable students to apply ENME380 material and that from other Mechanical Engineering papers, to develop a fully functioning prototype to meet a given design specification. Other material, such as power transmission, is assessed by exam.
