Multidisciplinary analysis of jet engine components : Development of methods and tools for design automatisation in a multidisciplinary context

Heikkinen, Tim, Müller, Jakob January 2015 (has links)
This thesis report presents the work of analysing current challenges in Multidisciplinary Analysis systems. Exemplary the system of an aerospace supplier, GKN Aerospace Sweden AB, is examined and several suggestions for improve- ment are implemented. The Multidisciplinary Analysis system, with company internal name Engineering Workbench, employs a set-based approach in exploring the design-space for jet engine components. A number of design cases with varied geometrical and environmental parameters is generated using Design of Experiment sampling methods. Each design case is then subjected to a set of analyses. Using the analyses results, a surrogate model of the parts behaviour in relation to the input parameters is created. This enables the product developer to get a general view of the model’s behaviour and also to react to changes in product requirements. Design research methodology is applied to further develop the Engineering Workbench into a versatile design support system and expand the functionality to include producibility assessment. In its original state, the execution of a study requires explicit domain knowledge and programming skills in several disciplines. The execution of a study is often halted by minor process errors. Several methods to improve this status are suggested and tested. Among those are the introduction of an interface to improve the usability and expand the range of possible users. Further the integration of a four level system architecture supporting a modular structure. Producibility assessment is enabled by developing an expert system where geometrical and simulation results can be caught, analysed and evaluated to produce producibility metrics. Evaluation of the implemented solutions indicate a step in the right direction. Further development towards Multidisciplinary Optimisation, involving experts in information technologies as well as case- based reasoning techniques is suggested and discussed.

Cross-functional Co-operation for Improved Product Development : - a case study at Siemens Industrial Turbomachinery AB

Alriksson, Maria, Aronsson, Lina January 2007 (has links)
The purpose of this thesis is to identify and analyze relevant dimensions of cooperation between design and production related to product development. The study also focuses on suggesting improvements of the co-operation dimensions between production departments and the product development departments in the Product Development Process (PDP) at Siemens Industrial Turbomachinery AB (SIT AB). SIT AB produces gas and steam turbines. Their increasing production pace and increasing number of product development projects have highlighted the importance of improved co-operations between departments within the company. We have developed an analysis model including the dimensions of co-operation we found relevant for the study. These are Timing of Upstream – Downstream Activities; Richness & Quality of Information; Frequency of Information Transmission; Direction of Communication; Formalization of Communication; Organizational Support; Goal Optimization; Attitudes in Cross-functional Teams; and Understanding of Tasks. For product development SIT AB follows an extensive process; the PDP. This is a sequential process where all activities are performed in sequence and therefore it obstructs the implementation of Concurrent Engineering. Concurrent Engineering aims to shorten development time and to consider the total job as a whole by performing independent activities in parallel. Hence, we argue that SIT AB should work toward a more integrated process with more parallel activities. The performance in all the dimensions of co-operation differ between large and small projects since the co-operation in large projects work much better than in small projects due to better followed process description; more face-to-face discussions; a better balance between informal and formal communication; and more focus on project goals and team building. The improvement proposals are presented in a separate chapter as actions classified according to the potential impact on the organization and the estimated difficulty to implement them. The proposals include for example: training more project managers; initiate work shop practice for design engineers; and give more and better explanations of decisions and actions. / Syftet med det här examensarbetet är att identifiera och analysera relevanta dimensioner av samarbete mellan produktion och konstruktion i samband med produktutveckling. Syftet är också att föreslå förbättringar i samarbetet mellan produktions- och konstruktionsavdelningarna i produktutvecklingsprocessen (PDP) på Siemens Industrial Turbomachinery AB (SIT AB). SIT AB producerar ång- och gasturbiner. Betydelsen av ett gott samarbete mellan avdelningar i organisationen har belysts i samband med att produktionstaken de senaste åren har ökat och fler produktutvecklingsprojekt har initierat. Vi har utvecklat en analysmodell som innehåller de dimensioner av samarbete som vi anser är relevanta för området. Dessa är: timing av uppströms – nedströms aktiviteter, rikhet & kvalitet på information, frekvens av informationsöverföring, riktning på kommunikation, formalisering av kommunikation, organisatoriskt support, måloptimering, attityder i tvärfunktionella team samt förståelse för uppgifter. Vid produktutveckling följer SIT AB den omfattande processen PDP. PDP är en sekventiell process där alla aktiviteter utförs i en sekvens vilket motverkar implementeringen av Concurrent Engineering. Concurrent Engineering syftar till att korta utvecklingstiden för produkter och beakta arbetet ur ett helhetsperspektiv bland annat genom utförande av oberoende aktiviteter parallellt. Därför anser vi att SIT AB ska arbeta mot en mer integrerad process med fler parallella aktiviteter. Det är stor skillnad på prestationen i samarbetsdimensionerna mellan stora och små projekt. Stora projekt fungerar mycket bättre än små vilket kan relateras till att stora projekt följer processbeskrivningarna bättre, har en bättre balans mellan informell och formell kommunikation, och fokuserar mer på projektmål och sammansvetsade projektgrupper. Förbättringsförslagen är presenterade som konkreta åtgärder i ett separat kapitel och är klassificerade med hänsyn till varje förslags potentiella effekt på organisationen och dess uppskattade svårighetsgrad att implementera. Förslagen är bland annat att utbilda fler projektledare, inrätta verkstadspraktik för konstruktörer och ge fler och bättre förklaringar till beslut och handlingar.

The importance of communication infrastructure in concurrent engineering : a thesis submitted in partial fulfilment of the requirements for the degree of Master of Engineering in Computer Systems Engineering at Massey University, Albany, New Zealand

McGillan, Rusul January 2009 (has links)
Concurrent engineering is an imperative concept in the world of product development. With the globalisation of industry, the market has been demanding higher quality products at lower costs, delivered at faster pace. With most companies today accepting the concurrent engineering approach as a formula for product development success, this approach is becoming ever more popular and dominating over the slower sequential product development method. Fast changes in technology, forced design cycle time reduction, emergence of new information technology and methodologies, as well as other aspects such as organisational and behavioural basis caused the sequential design process to progress into a concurrent engineering approach. The basic concept behind the concurrent engineering approach is that all parts of the design, manufacture, production, management, finance, and marketing of the product are usually involved in the early stages of a product’s design cycle, enabling faster product development through extensive use of simulation. Its key approach is to get the right data for the right person at the right time. There are forces that govern changes in the product development, and these forces must be steered towards prompt response to competition and higher productivity in order for companies to exist and successfully expand in the global market place. Concurrent engineering is made up of four key dimensions, one of them the communication infrastructure dimension, which is the focus of this study. This study defines the information infrastructure dimension, and some of the tools and technologies that support communication and collaboration. It then discusses how to employ the concurrent engineering approach from a communication infrastructure dimension point of view, starting with assessing the current product development process and eventually envisioning the path to take to a successful concurrent engineering environment. Communication infrastructure technologies and tools can be seen as central to a company’s implementation of concurrent engineering, as shown in the case studies covered in this work.
