  1. 1. Development of Methodology for Finite Element Simulation of Overhead Guard Impact Test

    Master-uppsats, Linköpings universitet/Mekanik och hållfasthetslära

    Författare :Axel Hallén; Jacob Hjorth; [2022]
    Nyckelord :Explicit Finite Element Analysis; Forklift Overhead Guard; RADIOSS; Drop Test; Strain-Rate Sensitivity; Johnson-Cook; Plasticity; Explicit finita elementanalys; Skyddstak; Gaffeltruck; RADIOSS; Fallprov; Töjningshastighetsberoende; Johnson-Cook; Plasticitet;

    Sammanfattning : Forklifts that are capable of lifting heavy loads and reaching high lift heights are required by stan-dards to have an overhead guard to protect the operator from falling objects. The same standardsspecify a standardized procedure for testing the strength of these overhead guards. LÄS MER

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

    Master-uppsats, KTH/Hållfasthetslära

    Författare :David Chlebek; [2021]
    Nyckelord :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;

    Sammanfattning : 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.

  4. 3. Design and Crash Analysis of Ladder Chassis

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Monica Muthyala; [2019]
    Nyckelord :Crash Analysis; Finite element Analysis; Thickness Optimization.;

    Sammanfattning : A chassis is known as the carrying unit of an automobile, like the engine, transmission shaft and other parts are mounted on it. Ladder chassis has longitudinal rails which are connected along the length with crossmembers through welding or mechanical fasteners. Rectangular box section is chosen for the longitudinal rails of ladder chassis. LÄS MER

  5. 4. Design Analysis and Optimization of Front Underrun Protection Device

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Anil Sharma; [2018]
    Nyckelord :Finite Element Method; Topology Optimization; Crash Analysis.;

    Sammanfattning : Under-running of passenger vehicle is one of the major parameters to be considered during the design and development of truck chassis. Front Under-run Protection Device (FUPD) plays an important role in avoiding under-running of vehicles from front side of a truck. LÄS MER

  7. 5. Impact simulation of elastic fuel tanks reinforced with exoskeleton for aerospace applications

    Master-uppsats, KTH/Mekanik

    Författare :Prus Cerzary; [2015]
    Nyckelord :;

    Sammanfattning : The main subject of the thesis is impact simulation of an elastic fuel tank reinforced with a polymer exoskeleton. Thanks to its light weight and failure resistance, this type of design shows potential to be used in aerospace applications. LÄS MER
