  1. 11. Development of a Parallel Finite-element Tool for Dynamic Soil-structure Interaction : A Preliminary Case Study on the Dynamic Stiffness of a Vertical Pile

    University essay from KTH/Bro- och stålbyggnad

    Author : Mårten Ullberg; [2012]
    Keywords : dynamic stiffness and damping; finite-element analysis; steady-state analysis; parallel calculations; PETSc; piles; pile-groups;

    Abstract : This thesis has two major goals; first to develop scalable scripts for steady-state analysis, then to perform a case study on the dynamic properties of a vertical pile. The scripts are based on the numerical library PETSc for parallel linear algebra. This opens up the opportunity to use the scripts to solve large-scale models on supercomputers. READ MORE

  3. 12. Physical Modeling and Simulation Analysis of an Advanced Automotive Racing Shock Absorber using the 1D Simulation Tool AMESim

    University essay from Fluida och mekatroniska system; Tekniska högskolan

    Author : Maryam Sadeghi Reineh; [2012]
    Keywords : Passive shock absorber; hydraulic; 1D modeling;

    Abstract : Shock absorbers are crucial components of a vehicle’s chassis responsible for the trade-off between stability, handling, and passenger comfort. The aim of the thesis is to investigate the physical behavior of an advanced automotive racing shock absorber, known as TTR, developed by Öhlins Racing AB. READ MORE

  4. 13. Determining the pressure distribution on submerged 2D bodies using dissipative potential flow.

    University essay from KTH/Marina system

    Author : Mirjam Fürth; [2011]
    Keywords : ;

    Abstract : Globalization is reaching the furthest corners of the world and with globalizations comes a rising demand on transportation. In shipping; a significant cost both to the ship owners and the environment are the fossil fuels used for propulsion, even a small reduction in the wave resistance can bring considerable reductions both in operating costs and emissions for such ships.
