  1. 11. Development of a Vehicle Simulation Model Consisting of Low and High Frequency Dynamics

    University essay from Linköpings universitet/Fordonssystem

    Author : Dennis Belousov; [2016]
    Keywords : Vehicle dynamics; simulation model; parameter estimation; road profile characteristics; power spectral density;

    Abstract : As vehicle testing on existing vehicles is both time and resource consuming, the work of testing safety algorithms on vehicle is desired to be made more efficient. Therefore the goal of this thesis is to study and develop a vehicle simulation model that can simulate desired dynamics of existing and non-existing vehicles. READ MORE

  3. 12. Transfer Path Analysis of a Passenger Car

    University essay from KTH/MWL Marcus Wallenberg Laboratoriet

    Author : Jakub Cinkraut; [2015]
    Keywords : Transfer Path Analysis TPA ; Tyre cavity resonance; Deflection shape analysis; Source Path Contribution SPC SW; Impedance matrix method; Road decomposition method;

    Abstract : Even though there are no regulations on the interior noise level of passenger cars, it is a significant quality aspect both for customers and for car manufacturers. The reduction of many other car noise sources pushed tyre road noise to the forefront. READ MORE

  4. 13. Analysis and simulation of centrifugal pendulum vibration absorbers

    University essay from KTH/MWL Marcus Wallenberg Laboratoriet

    Author : Emma Smith; [2015]
    Keywords : CPA; Adams Car; drivetrain simulations; epicycloid; tuning;

    Abstract : When environmental laws are constricted and downsizing of engines has become the reality of the vehicle industry, there needs to be a solution for the rise in torsion vibrations in the drivetrain. These increased levels of torsion vibrations are mostly due to excitations from the firing pulses, which in turn have become increased due to higher cylinder pressures. READ MORE

  5. 14. Evaluation of performance of a smartphone application for measuring bike paths’ condition

    University essay from Institutionen för datavetenskap; Tekniska högskolan

    Author : Jonas Erlandsson; [2013]
    Keywords : Statistics; smartphone application; bike path; RMS; Gaussian process; Wavelets; Statistik; smartphoneapplikation; cykelvägar; RMS; Gaussian process; Wavelets;

    Abstract : There are several methods to measure surface evenness for car roads, but almost none for bike paths. Accordingly, VTI (the Swedish National Road and Transport Research Institute) have created a smartphone application which uses the accelerometers in the phone to measure the vibration from the road.

  6. 15. Wheel Induced Vibrations on Heavy Vehicles

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Hector Garcia; Emma Smith; [2013]
    Keywords : ;

    Abstract : Some of the most significant comfort disturbances in heavy vehicles can often be related to the wheels. In those cases, the vibration of the vehicle is excited by for example force variations within the tire, ovality of the tire or imbalance in the wheel. READ MORE
