  1. 1. Multibody simulations of vibrations in a truck’s steering system

    University essay from KTH/Matematik (Avd.)

    Author : Marcus Didenbäck; [2023]
    Keywords : Multibody simulation; Vibrations; Stiff differential equations; Equations of motion; Lagrange; Vehicle dynamics; Adams; Flerkroppssimulering; Vibrationer; Styva differentialekvationer; Rörelseekva-tioner; Lagrange; Fordonsdynamik; Adams;

    Abstract : This thesis aims to explore if multibody simulations is a suitable method to investigate vibrations in the steering system of trucks. Vibrations in the steering system and subsequently in the steering wheel is a common issue that automotive manufacturers face. READ MORE

  3. 2. An Overview of Rosenbrock-Krylov Methods for the Numerical Solution of Ordinary Differential Equations

    University essay from Lunds universitet/Matematikcentrum; Lunds universitet/Matematik (naturvetenskapliga fakulteten)

    Author : Jens Axelsson; [2021]
    Keywords : Rosenbrock-Krylov methods; Rosenbrock methods; Krylov subspace methods; stiff ODEs; Mathematics and Statistics;

    Abstract : This thesis offers an overview of the relatively new family of Rosenbrock-Krylov numerical methods for ODEs. These methods are a further development of Rosenbrock methods, using a lower-dimension approximation of the Jacobian. READ MORE

  4. 3. Classification of stiffness and oscillations in initial value problems

    University essay from Lunds universitet/Matematik LTH

    Author : Marcus Valtonen Örnhag; [2015]
    Keywords : Mathematics and Statistics;

    Abstract : The spectrum of a linear, constant coefficient operator $A$ can help us characterize the system $\dot{x}=Ax$ satisfactorily, but in the case of a nonlinear dynamical system such methods are not suitable. In this thesis we discuss the insufficiency of only studying the eigenvalues along the Jacobian of the solution trajectory and discuss possible indicators to better characterize such systems.
