  1. 1. Material selection and topology optimization of a shift fork for metal 3D printing

    Master-uppsats, Uppsala universitet/Institutionen för materialvetenskap

    Författare :Rahul Amaralapudi Bala Vardha Raju; Raja Surya Mahesh Thammisetty; [2022]
    Nyckelord :Additive manufacturing; Topology optimization; Finite Element Analysis; SIMP; Generative design;

    Sammanfattning : In collaboration with Kongsberg Automotive, the thesis focuses on material selection and redesigning the shift fork for additive manufacturing using topology optimization. The shift fork is a component in the gear shifting mechanism in the automotive industry. The current shift fork at Kongsberg is manufactured from aluminum using die-casting. LÄS MER

  3. 2. Topology optimization : A comparison between the SIMP and BESO methods using open-source software.

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Tillämpad mekanik

    Författare :Christian Hagnell; Kiavosh Saidi Mosanen; [2021]
    Nyckelord :Strukturoptimering; Solid Isotropic Material with Penalization; SIMP; Bidirectional Evolutionary Structural Optimization; BESO; statiskt obestämd balk; 3D utskrift; bärande balk; öppen källkod; FreeCAD; Python;

    Sammanfattning : Structural optimization is a useful tool for engineers and designers in construction technology as well asvehicle and mechanical engineering. With structure optimization, a computer can, with the help of finiteelement analysis, calculate the smallest possible amount of material needed to meet the requirements onthe part to be produced.

  4. 3. An Algorithm for Structural Topology Optimization of Multibody Systems

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Toheed Ghandriz; [2014]
    Nyckelord :Dymola; Abaqus; TOSCA; nonlinear Differential Algebraic Equation; finite element method; flexible body; SIMP; dynamic body; Topology Optimization of Multibody Systems; flying element; Technology and Engineering;

    Sammanfattning : Topology Optimization (TO) of static structures with fixed loading is a very interesting topic in structural mechanics that has found many applications in industrial design tasks. The extension of the theory to dynamic loading for designing a Multibody System (MBS) with bodies which are lighter and stronger can be of high interest. LÄS MER

  5. 4. Topology optimization of load-carryingstructures using three different typesof finite elements

    Master-uppsats, KTH/Optimeringslära och systemteori

    Författare :Shoaib Ahmed; [2013]
    Nyckelord :;

    Sammanfattning : This thesis deals with topology optimization of load-carrying structures, in particular compliance minimization subject to a constraint on the total amount of material to be used. The main purpose of the work was to compare the following three types of finite elements for the above topology optimization problems: Four node square elements with bilinear shape functions, nine node square elements with quadratic shape functions, and six node hexagonal elements with Wachspress shape functions.

  7. 5. Nutrient Driven Topology Optimization

    Master-uppsats, Mekanik

    Författare :Ganarupan Satha; [2010]
    Nyckelord :;

    Sammanfattning : The aim of this thesis is to investigate how a biological structure changes its shape and boundary under different cases of load if flow of nutrients is included, since nutrient flow has not been taken into account in previous studies. In order to simulate such a scenario we construct a model by using topology optimization (the SIMP model) and a balance law which is suitable for biological structures. LÄS MER
