  1. 6. Effective Optimization of Deployment for Wearable Sensors in Transfemoral Prosthesis

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

    Author : SURANJAN RAM OTTIKKUTTI; [2020]
    Keywords : Sensors; globaloptimization; geneticalgorithms; patternsearch; transducers; transfemoralamputation; Sensorer; global optimering; genetiska algoritmer; mönstersökning; transduktorer; transfemoral amputation;

    Abstract : Transfemoralor above-the-knee amputees face discomfort in their prothesis primarily due to irregular distribution of pressure and shear forces in the Socket-stump interface (SSI). To quantify this discomfort it is necessary to first determine the pressure distribution in the SSI using sensors. READ MORE

  3. 7. Extraction of tool reaction forces using LS-DYNA and its use in Autoform sheet metal forming simulation

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Esbjörn Zachén; [2019]
    Keywords : Sheet Metal Forming; Stamping Die; blank holder; Structural Analysis; Finite Element Simulation;

    Abstract : In product development there is still potential to decrease lead times with faster and more accurate simulations. The objective of this thesis was to study whether Finite Element (FE) simulations using explicit LS-DYNA to extract reaction forces from sheet metal forming tools during forming, could be used to improve existing FE models in sheet metal forming software AutoForm.

  4. 8. An Attempt Towards FE-Modelling of Fracture Propagation in Railway Wheels

    University essay from KTH/Spårfordon

    Author : Fred Öhnander; [2018]
    Keywords : Railway wheel; Wheel-rail contact; Wear; Fracture initiation; Physical fracture propagation model; FE-model; Fracture mechanics; XFEM; Inclusion; Järnvägshjul; Hjul-räl-kontakt; Slitage; Sprickinitiering; Fysisk sprickbildningsmodell; FE-modell; Frakturmekanik; XFEM; Imperfektion;

    Abstract : The demand for higher velocities and heavier axle loads for freight trains leads to higher forces on the railway wheels which in turn lead to an increase in stresses on and below the surface of the wheel-rail contact. By time, this induces wear on the wheels which consequently lead to higher maintenance costs and in some cases accidents. READ MORE

    Abstract : “Overworking to death” is a phenomenon that has been noticeable in developing countries. The cause of death is mainly through ischemic strokes. While the victims’ occupations differed, they all shared a common characteristic, being positioned in a sedentary work, ranging from IT workers to doctors. READ MORE

  6. 10. Klövhälsa, klövverkning och underlag
