  1. 31. Estimation of Blocked Forces in an Assembly with Rear Drive Unit as a Source

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Srujeeth Khanna Bala; [2021]
    Keywords : Component based TPA; source characterized forces; FEM; Contact forces; ISO20270:2019; Blocked forces; Automotive; NVH; sound and vibration; komponentbaserad TPA; karaktärisering av bullerkällor; FEM; kontaktkrafter; blockerade krafter; bilindustri; ljud och vibrationer; ISO20270:2019;

    Abstract : Experimental validations are widely used for studying dynamic structural behaviors and these studies involve defining the structures completely as being used in real time. While in numerical simulations such detailed features are not specified to ease the computation, thereby deviating from accurate results. READ MORE

  3. 32. Test Equipment for Physical Testing of Vibration Isolator

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

    Author : ADAM ALVETEG; MARKUS JOHANSSON; [2021]
    Keywords : Test rig; vibration isolator; hysteresis; Testrigg; vibrationsisolator; hysteres;

    Abstract : Vibrations is a phenomenon that can cause problems to systems if not dealt with. In heavy duty trucks, vibrations are mainly caused by uneven roads and from the combustion engine. Vibrations can damage components, reduce their service life and cause discomfort for the driver.

  4. 33. Flight Simulator Integration in Test Rig

    University essay from KTH/Flygdynamik

    Author : Tilda Sikström; [2021]
    Keywords : Flight Simulation; JSBSim; Iron Bird; real-time; Simulink; Flygsimulering; JSBSim; Iron Bird; realtid; Simulink;

    Abstract : Integrating hardware in simulations is useful in many applications, for example to investigate the performance of an aircraft with the non-ideal response of a physical system. This thesis aims to integrate a flight simulator, JSBSim, with an actuator test rig, FLUMES Iron Bird. READ MORE

  5. 34. Design and validation of the control systemfor a Pin-on-Disc Machine

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

    Author : SIMON CALMINDER; JONAS XU; [2021]
    Keywords : Pin-on-Disc; Tribometer; Model; PID; Control; Pinne-skiva; Tribometer; Modell; PID; Reglersystem;

    Abstract : The friction between the under-head of a bolt and the mounting surface affects the necessary torque from a tightening tool. To study the friction behaviour during a highly dynamic tightening process, a Pin-on-Disc testrig has been developed. READ MORE

  6. 35. Development of Inlet Valve in an Oil­-free Novel Steam Engine

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Gautam Rajeev; Dinesh Thirunavukkarasu; [2021]
    Keywords : Steam engine; rotational valve; actuator mechanism; sealing; Ångmotor; rotationsventil; ställdon; tätning;

    Abstract : A novel compact steam engine design could be used to replace current combustion engines in the rapidly changing world of renewable energy. Especially with the increased research into alternative fuels such as hydrogen fuel cells and methane, which would vastly improve the efficiency of a steam engine. READ MORE
