  2. 1. Compression moulding of SMC : experiments and simulation

    Author : Jimmy Olsson; Daniel Ståhlberg; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : Due to excellent properties and relatively low material and manufacturing costs, the use of fibre reinforced polymer composites have increased during the last decades. One method that is suitable for large scale productions of e.g. lightweight vehicle components is compression moulding of sheet moulding compound (SMC). READ MORE

  4. 2. Design, Modelling and Control of Electrical Machines - With Applications to Iron-powder Machines and Acoustic Noise

    Author : David Martinez; Industriell elektroteknik och automation; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; BEM; induction machine; noise prediction; vector control; acoustic noise; HEV; series magnetization; leakage reduction; thermal model; FEM; MEC; claw-poles; SMC; slip-ring-less machine; sound intensity measurements; vibration; Electrical engineering; Elektroteknik;

    Abstract : This thesis consists of two parts, the first dealing with the design of iron-powder synchronous machines, and the second with the analysis and prediction of the acoustic noise in electrical machines. In Part I, a 1.6 kW electrically magnetized claw-pole machine with magnetically conducting end-plates has been analyzed and a prototype tested. READ MORE

  5. 3. CVD on Iron Powder - Using Fluidising Bed Techniques

    Author : Lars Nilsson; Industriell Produktion; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aluminium oxide; alumina; chemical vapour deposition; eddy current losses; FBR; iron; fluidising bed reactor; powder; SiO2; SMC; TiO2; Al2O3; soft ma etic com sites; CVD;

    Abstract : Today's electrical energy conversion devices, such as motors, transformers, inductors and generators, are based on laminated magnetic cores for reduction of eddy current losses, imposing a two-dimensional magnetic flux distribution. Using a three-dimensional magnetic flux distribution while maintaining low magnetic losses requires new approaches to magnetic core materials. READ MORE

  6. 4. Mechanical Behaviour of SMC Composites and Structures

    Author : Magnus Oldenbo; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

    Abstract : The goal of this work has been to investigate the influence of material composition and process induced fiberorientation on mechanical properties of SMC composite body panels. It has also been a goal to study methods to predict the properties. READ MORE

  7. 5. Anisotropy and non-linear effects in SMC composites : from material data to FE-simulation of structures

    Author : Magnus Oldenbo; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

    Abstract : In the design of composite structures for the automotive industry it is vital to have good tools because development time is very critical. Normally simulation of mechanical properties of sheet moulding compound (SMC) composite structures is stiffness based and limited to isotropic material model. READ MORE
