Course Overview

Aimed at students interested in mechanical engineering and aims to equip students with the skills and knowledge required to take a design requirement/concept to a fully implemented product.  It will provide an overview of a multi-stage design methodology followed by procedures for the detailed design of various mechanical elements including gears, shaft and bearings.  These procedures will include design to resist fatigue failure and will be taught using an example product.  The course will include aspects of sustainability and choice of method for manufacture. Assessed through a series of group design exercises.

Course Description

The course starts with a review of the five-stage design procedure including methods of evaluation of alternative designs.  This is followed by lectures on fitness for purpose, sustainability in design.

An overview of the application of fatigue analysis in design including the use of S/N curves and the modified Goodman diagram for the assessment of fatigue life for fluctuating loading is presented.  This is followed by a series of design lectures on the detail design of mechanical components including:

·         gears design using the modified Lewis formula

·         rolling element bearing selection and life estimation

·         static and fatigue analysis of shafts with combined torsional, bending and axial loading

·         seal selection for rotating and sliding applications

·         threaded connection design for fatigue loading, covering failure by opening of the joint and deformation of the threaded element.

·         spring design for tension, compression and torsional coil springs.

Dimensioning for manufacture, including the effect of dimensioning from various datum points and chain dimensioning, tolerancing of dimensions and limits and fits is also included.  The course concludes with a section on the choice of manufacturing process for prototype/one off, small batch and mass production for manufacture including welding, machining from billet, casting, forging and moulding.

Total 16 one-hour lectures and 11 three-hour design sessions
