  1. 6. Investigation on Road Noise Transmission through Steering System

    Master-uppsats, KTH/MWL Marcus Wallenberg Laboratoriet

    Författare :Yuan Xie; [2017]
    Nyckelord :Blocked force method; vehicle NVH test; coupled system;

    Sammanfattning : An investigation on noise transmission through the steering gear system is focused on the area of vehicle NVH (Noise Vibration and Harshness). From previous investigations it is well known that noise transmission through the steering system sometimes has a significant influence referring to tire road noise. LÄS MER

  3. 7. Dämpning av ljud i Shift-by-Wire växelväljare : Noise damping in a Shift-by-Wire gear shifter

    Kandidat-uppsats, Högskolan i Jönköping/JTH, Maskinteknik

    Författare :Sebastian Karlsson; André Boberg; [2015]
    Nyckelord :Växelväljare; Shift-By-Wire; Oljud; Noise; Vibration Harshness; Orsaksanalys; Kongsberg Automotive; Konceptgenerering;

    Sammanfattning : Constantly growing demands from the costumers in the Automotive industry forces the subcontractors to seek alternative ways to compete. One parameter of quality is the components tolerance against NVH(Noise, Vibraion & Harshness) aspects. LÄS MER

  4. 8. Methodology for Multidisciplinary Optimization of Vehicle Suspension Systems

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Hållfasthetslära

    Författare :Martin Wollstad; Alexander Sallbring; [2015]
    Nyckelord :Technology and Engineering;

    Sammanfattning : A manual iterative process is often used in the design process of vehicle suspension systems. This thesis aim to develop a methodology for multidisciplinary optimization of vehicle suspension systems, which can be used to introduce an optimization driven process into the design process of vehicle suspension systems.

  5. 9. A Study of Active Engine Mounts

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

    Författare :Fredrik Jansson; Oskar Johansson; [2003]
    Nyckelord :Reglerteknik; active engine mount; actuator; active vibration control; electromagnetic actuator model; parameter estimation; Reglerteknik;

    Sammanfattning : Achieving better NVH (noise, vibration, and harshness) comfort necessitates the use of active technologies when product targets are beyond the scope of traditional passive insulators, absorbers, and dampers. Therefore, a lot of effort is now being put in order to develop various active solutions for vibration control, where the development of actuators is one part. LÄS MER
