  1. 1. 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. 2. A Friction Model for Laminator Nips

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Stefan Oros; [2015]
    Keywords : friction; LuGre; modelling; Stribeck; sliding; carton; Technology and Engineering;

    Abstract : The main objective for the thesis project is to find a suitable mathematical model of the velocity dependent friction force that arises between the nip roller and the carton material in the laminator at slip, in order to enable realistic simulations of the nip in the laminator. Theoretically, the LuGre model is found to contain the necessary physical properties for the actual situation. READ MORE

  4. 3. Realisation and evaluation of a start-stop journal bearing test-rig

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Marcus Gralde; Tómas Rúnar Sölvason; [2014]
    Keywords : journal bearing; hydrodynamic lubrication; wear; start-stop; test-rig; glidlager; hydrodynamisk smörjfilm; nötning; start-stop; testrigg;

    Abstract : While there has been substantial body of work in the field of journal bearing research, much of it is today theoretical or simulated due to today’s computing power. Scania produces experimental data from motor testing, but these are expensive and time consuming. READ MORE

  5. 4. Speed dependent friction in bolt joints

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Arvid Blom; [2013]
    Keywords : Bolt joint; friction; Stribeck; speed dependent; load distributio; Skruvförband; friktion; Stribeck; hastighetsberoende; tryckfördelning;

    Abstract : Denna rapport undersöker hastighetsberoende friktionsbeteende i zinkpleterade 8.8 M12x1.75 skruvförband med en klämlängd på 82 mm och ett åtdragningsmoment på 120 Nm. Totalt 84 åtdragningar genomförs med nya skruvar, brickor och muttrar för varje åtdragning med utrustning tillhandahållen av Atlas Copco. READ MORE

  6. 5. Model-based Friction Compensation

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Timothée Basson; Julien Lescot; [2009]
    Keywords : dSPACE; Limit Cycle; Furuta Pendulum; LuGre Model; Friction Compensation; Technology and Engineering;

    Abstract : Friction is present in all mechanical systems and causes a wide range of problems for control. The development of model-based strategies accounting for Friction in the designed control has been a vast area of Research since these last decades. READ MORE
