This report provides background and guidance on the use of the structural hot spot stress approach to the fatigue design of welded components and structures. It complements the IIW recommendations for 'Fatigue Design of Welded Joints and Components' and extends the information provided in the IIW recommendations on 'Stress Determination for Fatigue Analysis of Welded Components'. This approach is applicable to cases of potential fatigue cracking from the weld toe. It has been in use for many years in the context of tubular joints. The present report concentrates on its extension to structures fabricated from plates and non-tubular sections.Following an explanation of the structural hot spot stress, its definition and its relevance to fatigue, the authors describe methods for its determination. Stress determination from both finite element analysis and strain gauge measurements is considered. Parametric formulae for calculating stress increases due to misalignment and structural discontinuities are also presented. Special attention is paid to the use of finite element stress analysis and guidance is given on the choice of element type and size for use with either solid or shell elements. Design S-N curves for use with the structural hot spot stress are presented for a range of weld details. Finally, practical application of the recommendations is illustrated in two case studies involving the fatigue assessment of welded structures using the structural hot spot stress approach.

The holistic view of powertrain development that includes engine, transmission and driveline is now well accepted. Current trends indicate an increasing range of engines and transmissions in the future with, consequently, a greater diversity of combinations. Coupled with the increasing introduction of hybrid vehicles, the scope for research, novel developments and new products is clear. This volume presents a collection of papers from the Institution of Mechanical Engineers Conference Integrated Powertrain and Driveline Systems 2006 (IPDS 2006) organised by the IMechE Automobile Division. Main themes include transmissions; concept to market evolution; powertrain integration; and engine integration. Novel concepts relating, for example, to continuously variable transmissions (CVTs) and hybridization are discussed, as well as approaches to modelling and simulation.

Rotating machinery (eg pumps, motors, compressors) is normally manufactured to precise measurements but there comes a point when the costs of manufacture mean that further precision is not cost-effective and thus any slight imbalance inherent in the machine will need to be attended to after manufacture. When such machinery is in operation, often at very high speeds of thousands of revs per minute, any imbalance will set up vibration and often noise. In addition, such imbalance will cause extra wear and loss of efficiency in the machine. The answer is to balance the affected parts of the machine so that it operates smoothly and efficiently.This book is a practical account of such balancing techniques e.g how to balance a rotor, how to set up and verify performance of a balancing machine, and procedures for on-site balancing. In addition, other common causes of vibration will be covered e.g. misalignment, bad bearings and looseness.This book is the distillation of a successful course run by the author and developed over 20 years. University engineering departments do not teach balancing techniques beyond the very basic, and there is a need for educators and engineers to have a practical book available on the topic.

Over recent years there have been substantial changes in those industries which are concerned with the design, purchase and use of special purpose (ie critical, high-revenue) rotating equipment. Key personnel have been the victims of early retirement or have moved to other industries: contractors and end-users have reduced their technical staff and consequently have to learn complex material 'from scratch'. As a result, many companies are finding that they are devoting unnecessary man hours to the discovery and explanation of basic principles, and having to explain these to clients who should already be aware of them. In addition, the lack of understanding by contractors and users of equipment characteristics and operating systems often results in a 'wrong fit' and a costly reliability problem.Forsthoffer's Rotating Equipment Handbooks: Auxiliary Systems deals with types, function and application of each major system type, (lubrication, control, liquid and gas seal, cooling, buffer gas and pump flush) component selection and design of reservoirs, pump systems, control valves and instrumentation, coolers/filters and transfer valves, design audits and troubleshooting of systems and components, maintenance, key reliability indicators, system condition monitoring and much more.Forsthoffer's Rotating Equipment Handbook: Auxiliary Systems is the forth title in the five volume set. The volumes are: 1. Fundamentals of Rotaing Equipment; 2. Pumps; 3. Compressors; 4. Auxiliary Systems; 5. Reliability Optimization through Component Condition Monitoring and Root Cause Analysis'.

'Fundamentals of Rotating Equipment' is an overview of the main types of rotating machinery in industry, and covers such aspects as system dynamics, surge control, vibration and balancing, radial bearing design, performance parameters, rotor system design and operation, rotor axial (thrust) forces, performance objectives and mechanical restraints, auxiliary systems and seals.This book will enhance rotating equipment reliability and safety throughout the many industries where such equipment is vital to a successful business.Over recent years there have been substantial changes in those industries which are concerned with the design, purchase and use of special purpose (ie critical, high-revenue) rotating equipment. Key personnel have been the victims of early retirement or have moved to other industries: contractors and end-users have reduced their technical staff and consequently have to learn complex material ‘from scratch’.

In addition, the lack of understanding by contractors and users of equipment characteristics and operating systems often results in a ‘wrong fit’ and a costly reliability problem. The stakes can be high, and it against this background that this book has been published. It is the outcome of many years experience and is based on well-honed teaching material which is easily readable, understandable and actually enjoyable!This is a five volume set. The volumes are: 1. Fundamentals of Rotating Equipment 2. Pumps 3. Compressors 4. Auxiliary Systems5. Reliability Optimization thru Component Condition Monitoring and Root Cause Analysis

Engineers employ shear connections - riveted and bolted butt and lap joints - in a wide range of structures and machines. Ordinary stress analysis of joints are unable to define the features that ultimately govern fatigue and fretting and provide bases for design. Detailed analysis has only become possible recently with advances in finite element methods and computing capabilities. This text places into context the results of over 150 detailed 2D and 3D finite element analyses of aluminum and steel shear connections so that engineers can optimise the design and reliability of shear joints.
