  1. 1. Simplification of CAD Geometries to perform CEM Simulations

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Farrukh Bashir; [2021]
    Keywords : Defeaturing; Modification; Blending Features; FEA; CEM; CAD; CAE.;

    Abstract : The purpose of this study is to investigate small features in CAD geometries which have high influence on computational time and memory consumption during electromagnetic simulations using CAE software. Computational Electromagnetics (CEM) simulations of complex CAD geometries like passenger cars crash often simulations remain incomplete due to a lot of irrelevant details. READ MORE

  3. 2. FE Modelling Of Two Femur Fixation Implants

    University essay from Linköpings universitet/Mekanik och hållfasthetslära

    Author : Ali Arsiwala; Vatsal Shukla; [2021]
    Keywords : FEM; Femur; Image Segmentation; Material Modelling; Recon Implant; Antegrade Implant; Atypical Femoral Fracture; Intermedullary Nail;

    Abstract : In the pool of women over the age of 50, the likeliness of an atypical fracture increase drastically, partly due to osteoporosis. With a pre-existing implant in the femur bone, inserted due to a prior atypical fracture, treating a later femoral neck fracture is complex and risky. READ MORE

  4. 3. Simulation of ultrasonic time of flight in bolted joints

    University essay from KTH/Hållfasthetslära

    Author : David Chlebek; [2021]
    Keywords : Acoustoelastic effect; User material subroutine; Murnaghan hyperelastic material model; Explicit FEM; Ultrasonic preload; Fortran; Akustoelastiska effekten; Användar material; Murnaghan hyperelastisk materialmodell; Explicit FEM; Ultraljudsmätning av klämkraft; Fortran;

    Abstract : Ultrasonic measurements of the preload in bolted joints is a very accurate method since it does not depend on the friction and other factors which cause difficulties for common methods. The ultrasonic method works by emitting an ultrasonic pulse into the bolt which is reflected at the end and returned to the transducer, the change in the time of flight (TOF) can be related to the elongation of the bolt and therefore the preload.

  5. 4. Methodology Development for Topology Optimization of Power Transfer Unit Housing Structures

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Povendhan Palanisamy; [2020]
    Keywords : Topology Optimization; Design interpretability; Housing structure; Design Volume; Response Functions and Parameters; Topologioptimering; designtolkbarhet; husstruktur; designvolym; svarsfunktioner och parametrar;

    Abstract : Simulation driven design is a method and process that has been developed over many years, and with today’s advanced software, the possibility to embed simulation into the design process has become a reality. The advantages of using simulation driven design in the product development process is well known and compared to a more traditional design process, the simulation driven design process can give the user the possibility to explore, optimize and design products with reduced lead time.

  6. 5. Feasibility study of modelling a virtual climate chamber with CFD

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Christina Silfwerbrand; [2020]
    Keywords : Virtual climate chamber; CFD; feasibility study;

    Abstract : The company tests their industrial tools in a climate chamber to assure that tools meet the ISO-standard requirements and to assure personnel safety. Since it takes time to prepare the physical tool and to get a time slot to test it, this process was a bottleneck. READ MORE
