  1. 1. Evaluation of Active Rear Steering through Multi-Body Simulation

    University essay from KTH/Väg- och spårfordon samt konceptuell fordonsdesign

    Author : Matteo Rossi; Gabriele Bertoli; [2021]
    Keywords : Vehicle dynamics; Active rear steering; active systems; automotive; MBS; Simpack; Volvo; CAE; single-track model; bicycle model; feedforward control; Vehicle dynamics; Active rear steering; active systems; automotive; MBS; Simpack; Volvo; CAE; single-track model; bicycle model; feedforward control;

    Abstract : The goal of this thesis work is to evaluate and quantify the advantages and disadvantages of Active Rear Steering (ARS). The evaluation is carried out through Multi-Body System (MBS) simulations. An analytical model has been developed to better understand the basic dynamics of vehicles equipped with rear steering.

  3. 2. Dynamic Simulation and Suspension Optimization for a Heavy Duty Railway Bogie

    University essay from KTH/Spårfordon

    Author : David Prifer; [2021]
    Keywords : Rail vehicle; Bogie Technology; Running Dynamics; Simulation; Simpack; Vehicle Acceptance; Validation; Järnväg; Gångegenskaper; Flerkroppssimulering; Acceptanskrav;

    Abstract : A multi-body simulation study was undertaken to investigate the running behavior of a rail grinder vehicle with newly developed Ganz bogies. The main purpose of the simulations was to forecast and support the vehicle acceptance tests and support the ongoing development. READ MORE

  4. 3. Dynamic Modelling of the KTH Roller Rig

    University essay from KTH/Spårfordon

    Author : Daniele Mario Fraschini; [2021]
    Keywords : rail vehicle dynamics; roller rig; scaling; track irregularities; validation; modelling; spårfordons dynamik; rullrigg; nedskalning; spårlägesfel; validering; modellering;

    Abstract : The Rail Vehicle Research group at Kungliga Tekniska Högskolan (KTH) is on the path to design and build a scaled test rig called roller rig for research and educational purposes. A roller rig is a device simulating the track with rollers on which the test subject (a wheelset, bogie or even a full vehicle) canbe placed. READ MORE

  5. 4. Improvement of Steering Performance of a Two-axle Railway Vehicle via Look-up Tables Estimation

    University essay from KTH/Spårfordon

    Author : Prapanpong Damsongsaeng; [2020]
    Keywords : Two-axle railway vehicle; Active steering system; Look-up tables; Time-varying wheel-rail contact parameters; Två-axligt järnvägsfordon; aktiv styrning; uppslagstabeller; tidsvarierande hjul-rälskontaktparametrar;

    Abstract : A conceptual design of an innovative two-axle lightweight railway vehicle for commuter services is carried out at KTH Railway Group. An active wheelset steering is introduced to improve the curving performance of the vehicle, which is one of the critical performance requirements. READ MORE

  6. 5. Implementation of Active Steering Fuzzy PID Controller on a Two-axle Railway Vehicle

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Yulei Qiu; [2020]
    Keywords : ;

    Abstract : This thesis investigates the improvement of curving performance of a two-axle railway vehicle using fuzzy PID controller. The control goal during curving is to maintain zero difference between front and rear yaw angle. A mathematical linear model is built up based on a two-axle railway vehicle. A nonlinear model is also created in SIMPACK. READ MORE
