  1. 11. Modelling of Automotive Suspension Damper

    University essay from KTH/Fordonsdynamik

    Author : Saurabh Vyas; Venkata Dinesh Raju Jonnalagadda; [2020]
    Keywords : Damper Model; hysteresis; least squares fitting; Stribeck friction model; Parameterization; FV curve; Damper test rig; Error matrix; Error plots; Multibody Simulation; MBS.; stötdämparmodell; hysteres; minsta kvadratpassning; Stribeck-friktionsmodell; Parametrisering; FV-kurva; stötdämpartestrigg; Felmatris; Feldiagram; Flerkroppssimulering; MBS;

    Abstract : A hydraulic damper plays an important role in tuning the handling and comfort characteristicsof a vehicle. Tuning and selecting a damper based on subjective evaluation, by considering theopinions of various users, would be an inefficient method since the comfort requirements of usersvary a lot. READ MORE

  3. 12. A 3D sliding bearing finite element based on the Bouc-Wen model : Implementation in Abaqus

    University essay from KTH/Bro- och stålbyggnad

    Author : Rémi Lantoine; [2020]
    Keywords : Railway bridge; dynamics; resonance; sliding bridge bearings; finite element; Abaqus; friction; steel; Teflon; PTFE; Bouc-Wen model; friction coefficient; temperature; heating;

    Abstract : As rail transportation is significantly more virtuous than airplanes or cars in terms of greenhousegases emissions, its development is being encouraged in several European countries, includingSweden. In addition, the development of railway lines on which trains can travel at higher speeds ismade in Sweden with the integration of existing infrastructure. READ MORE

  4. 13. Modelling a Novel Linear Transverse Flux Machine and Designing a Hysteresis Current Controller for Power Factor Correction

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Ahmed Alhaidari; [2019]
    Keywords : double band hysteresis current controller; linear machine; magnetic circuit model; power take-off; transverse flux permanent magnet synchronous machine; wave energy conversion;

    Abstract : In this thesis, the basics of electromagnetic theory for wave-energy conversion are reviewed, some of the characteristics of the ocean wave are investigated, some of the power take-off (PTO) systems are introduced, and details about linear permanent magnetic machines, in particular, are discussed.  The thesis aims to model the novel linear transverse flux machine designed by Anders Hagnestål and to build hysteresis current controller for power factor correc- tion.

  5. 14. Advanced bushing script program in MSC ADAMS

    University essay from KTH/Fordonsdynamik

    Author : Rahul Gowthaman; Suhail Jagwani; [2018]
    Keywords : MSC ADAMS Car; rubber bushing; Computer Aided Engineering; stiness; measured data; force hysteresis; dynamic loading;

    Abstract : The thesis focuses on investigating and optimizing a bushing script implemented as a tool in MSC ADAMS/Car. The study provides an insight on the representation of a rubber bushing and identify parameters which can be used to define the properties of a bushing in a simulation environment such as ADAMS/Car.

  6. 15. Some deviations from linear dynamics due to more accurate damping models

    University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Author : Jakob Sjöstrand; [2017]
    Keywords : Bilinear hysteresis; Standard linear solid; SLS; Linear Dynamics; Non-linear Dynamics; Technology and Engineering;

    Abstract : Damping is present in all dynamic systems. In one way or another energy is being dissipated in the system. To capture this aspect of reality in a computational model is a difficult task. A common simplification is to assume that the damping is of a linear viscous nature. READ MORE
