  1. 1. Development of Test Methodology for Electromechanical Linear Actuators

    University essay from Uppsala universitet/Signaler och system

    Author : Isak Linder; [2022]
    Keywords : Electromechanical; linear actuator; test methodology; test rig; rack and pinion; transport delay; latency; spring mass damper; load cell; load force; load unit; test unit; DUT; PID; PID control; control mechanics; cogging torque; torque; flex; stiffness; current saturation; torque control;

    Abstract : This master thesis aims to develop a test methodology for electromechanical linear actuators. A linear actuator acts as a linear motor, converting a power source to linear motion. The electromechanical linear actuator in this project has an electric motor as its power source and uses a rack and pinion system to transfer that power to linear motion. READ MORE

  3. 2. 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

  4. 3. Dynamic Simulation of a One-Cylinder Engine Test Rig

    University essay from KTH/Hållfasthetslära (Inst.)

    Author : Per Sundström; [2017]
    Keywords : ;

    Abstract : An engine test rig at AVL was redesigned with new components after a failure. The new system consists of a torsional vibration damper, a cardan axle, a torque flange, and an adapter unit, together with a new dynamometer. To ensure another failure would not occur a study of the new system was conducted. READ MORE

  5. 4. Development of software that can predict damper curves on shock absorbers

    University essay from Institutionen för teknikvetenskaper

    Author : Erik Gelotte; [2013]
    Keywords : Stötdämpare; dämparkurvor; settingbank; plotfunktion;

    Abstract : This thesis features the development of a software program with a plot function (a setting bank) for data curves, obtained when car dampers are tested in a dynamometer, which measures forces at given velocities. Advanced dampers have many different adjusting possibilities and it was desired to collect data about this for a number of damper types, in a software program that can be used to predict damper curves without having to perform actual tests.

  6. 5. Analysis of simplified dynamic truck models for parameter evaluation

    University essay from KTH/Fordonsdynamik

    Author : Ted Lundberg; [2013]
    Keywords : ;

    Abstract : The ride comfort in heavy commercial trucks is an important property that requires detailed testing to investigate how different vehicle components affect the response to road input. Trucks come in many different configurations and a customer purchasing a new truck often has the choice to specify number of axles, drive line and cabin type, type of suspension and so on. READ MORE
