  1. 1. Dynamic axel load estimation for an electrified vehicle : Normalkraftestimering på drivaxeln

    University essay from Linköpings universitet/Institutionen för systemteknik

    Author : Majd Barakat; [2023]
    Keywords : Vehicle dynamics; Suspension systems; Vehicle design; Bounce-Pitch model; Car quarter model; Normal force; Normal force estimation;

    Abstract : The brake system is critical for ensuring safe driving and has been the focus of development for many years. Pneumatic braking technology is commonly used in heavy vehicles,but it results in energy wastage and high service costs. Some countries mandate auxiliarybraking systems to assist in stopping the vehicle in addition to service brakes. READ MORE

  3. 2. Test Rig Development for Real Time Clamping Force Estimation in Threaded Tightenings with Implemented Extended Kalman Filtering

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Annie Farell; [2023]
    Keywords : Clamping force; Threaded Fastener; Extended Kalman Filtering; Test Rig Development; Real Time Estimation; Sensor Placement.; Klämkraft; gängad fästelement; utökad Kalman filtrering; testrigsutveckling; estimering i realtid; sensorplacering.;

    Abstract : The clamping force between the components during bolt tightening is of great interest, and it has been the focus of developing new tightening techniques for a long time. Today there is no easy or practical method to directly measure the clamping force in a typical production situation. READ MORE

  4. 3. Tire and force distribution modeling and validation for wheel loader applications.

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : John Spencer; Bernhard Wullt; [2017]
    Keywords : Tire model; Force distribution model; Wheel loader; normal force; Magic formula;

    Abstract : This thesis describes the development of a machine force distribution estimator and the calibration of tire models for wheel loader applications. Forces generated in the contact patch between the tires and the ground are crucial for understanding and controlling machine dynamics. READ MORE

  5. 4. Application of transmissibility measurement in estimation of modal parameters for a structure

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : AmirHossein Aghdasi; [2013]
    Keywords : Operational Modal Analysis; Transmissibility measurement; mode shape; MATLAB.;

    Abstract : Identification of modal parameters from output-only data is studied in this work. The proposed methodology uses transmissibility functions obtained under different loading conditions to identify resonances and mode shapes. The technique is demonstrated with numerical simulations on a 2-DOF system and a cantilever beam. READ MORE

  6. 5. Algorithm for Estimation of Wheel-Rail Friction Coefficient from Vehicle-Track Forces

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

    Author : Vladislav Petrov; [2012]
    Keywords : wheel-rail friction; friction coefficient; estimation of friction; contact point; vehicle simulation; vehicle certification;

    Abstract : In order to ensure safe travel, railway vehicles must be stable under every condition along the track. Thus, a vehicle can be certified for operation only when it can fulfil certain criteria related to the ride stability. The stability of the vehicle is highly dependent on the wheel-rail friction coefficient: higher friction results in worse ride. READ MORE
