  1. 1. A personalized quasi-passive ankleexoskeleton using human-in-the loop optimization approaches

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

    Author : Ho Ming Kong; [2023]
    Keywords : ;

    Abstract : Passive ankle exoskeletons have been proven to successfully decrease muscle demand for walking. The movement of the user’s ankle drives a mechanical clutch and spring, which eventually stores and returns mechanical energy to the user. READ MORE

  3. 2. Design and Development of a Foldable Motorized Micro-Haulage Vehicle

    University essay from Lunds universitet/Innovation

    Author : Gustaf Andersson; Mårten Lönn; [2023]
    Keywords : Product Development; Additive Manufacturing; Topology Optimization; Walking; Micro-Haulage Vehicle.; Technology and Engineering;

    Abstract : This thesis describes the process of designing and developing a foldable motorized micro-haulage vehicle, which follows the user, for urban transportation. The project is made in collaboration with Volvo Car Corporation. The transportation industry stands as a significant contributor to greenhouse emissions. READ MORE

  4. 3. A Feasibility Analysis of Natural Composite Alternatives in High Performance Sailing Vessels

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Sabrina Smith; [2023]
    Keywords : F50 catamaran; sustainable materials; marine applications; flax laminates; mechanical testing; environmental analysis; weight distribution; yacht performance;

    Abstract : The construction of high-performance vessels like the F50 catamaran has traditionally prioritized advanced composite materials and performance-driven design. However, there is a growing need to incorporate sustainable materials and practices, with their performance in marine applications remaining relatively unknown. READ MORE

  5. 4. Multi-Scale Topology Optimization of Lattice Structures Using Machine Learning

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Julia Ibstedt; [2023]
    Keywords : Topology optimization; Multi-scale topology optimization; Machine learning; Gaussian process; Homogenization; Inverse homogenization; Anisotropic materials; Symmetry groups; Material property space; Topologioptimering; Flerskalig topologioptimering; Maskininlärning; Gaussian process; Homogenisering; Anisotropa material; Symmetrigrupper; Materialegenskapsrymd;

    Abstract : This thesis explores using multi-scale topology optimization (TO) by utilizing inverse homogenization to automate the adjustment of each unit-cell's geometry and placement in a lattice structure within a pressure vessel (the design domain) to achieve desired structural properties. The aim is to find the optimal material distribution within the design domain as well as desired material properties at each discretized element and use machine learning (ML) to map microstructures with corresponding prescribed effective properties.

  6. 5. Exploratory study on Additive Manufacturing in Urban mobility

    University essay from

    Author : Kaustubh Deshmukh; [2023]
    Keywords : ;

    Abstract : This thesis report presents a comprehensive study on the design and development of an Additively manufactured Unit cell for car door panels, aiming to enhance impact resistance and reduce noise transmission to the vehicle cabin. In order to accomplish these goals, the study focuses on combining two novel techniques namely quasi-zero stiffness (QZS) structures and phononic crystals (both scattering and locally resonating type).
