Summary of Content

The aim of this module is to impart knowledge in advanced aspects of the engineering design, materials selection, manufacture and assembly (including robotics) with regard to mechanical and power plant components .


Optimum Design Techniques & Fail Safe Design: Principles of optimum design concepts, constrained and unconstrained, global optimality, practical design optimisation and safe and fail safe design. Application to nuclear, aerospace and other critical systems. Illustrative case studies. Design Validation: The design audit and the supportive role of engineering analysis and experimentation. Prototypes, rapid prototyping, reliability and warranty, consumer reaction. Fault tree analysis, failure mode effect and criticality analysis. British Standards Codes of Practice: Application of British Standard design code methodology to an engineering structure, system or components, e.g. BS5500 - Design of pressure vessels. Materials and Process Selection in Design Principles of engineering selection systems, and its requirements, Systematic approach to material and process selection to optimise design. The structure of the selection process, database requirements and validation, and e- information sources. The examples and case studies are drawn from the selection of materials and processes, but the principles are general, and apply equally to a wide range of selection problems. The software package, Cambridge Engineering Selector (CES) is used for this systematic approach in selection for design. Criteria and Tools for Materials Selection: Physical Factors; Mechanical Factors; Processing and Fabricability; Life of components; Cost and availability; Codes, statutory, and other factors; Merit indices; Materials charts; Software and Database packages; Objectives in conflict: trade-off methods and penalty functions Environmental Issues & Sustainability: Eco-selection: environmentally informed material choice; sustainability, LCA Robotics Advantages and limitations of robotics for industrial applications and where they can be applied by a practicing engineer. End effector types, control schemes, joint types, programming methods (pendant/simulation), safety implications, cost justification, barriers to implementation, benefits of robotisation, teleoperation. Design for Manufacture DFM Features of robotic systems that the Engineer needs to be aware of, repeatibility, accuracy for specific processes, locations techniques Design for Assembly Product design interaction with Robotic Assembly, simplifications, comparison with manual assembly techniques, key features, Degrees of freedom.

Learning Outcomes

On completion of this module the student should be able to:1. Recognise the need for Design Validation, demonstrating a knowledge of alternative methods available.2. Apply a systematic approach to select optimum materials and manufacturing processes; Derive performance Indices for mechanical/thermo mecahnical components and utilise these in merit ranking. 3. Appraise components/processe/systems on their environmental effects/sustanability utilising Life Cycle Analysis (LCA) tools.4. Apply techniques of optimisation to the design of components.5. Utilise effective analysis techniques in design for assembly & manufacture.6. Apply British standards design methodology to the design of an engineering structure component or system.7. Recognise basic Robot configurations SCARA, Cartesian, cylindrical, spherical and how they would be applied in an industrial context. Use of robot simulation software/ CAD interaction to select a Robot system (funding dependant).
