  1. 11. Drag Torque and Synchronization Modelling in a Dual Clutch Transmission

    University essay from Lunds universitet/Maskinelement

    Author : Mikael Lund; [2018]
    Keywords : drag torque; synchronization; dual clutch transmission; Technology and Engineering;

    Abstract : Noise, vibration and harshness (NVH) is a big consideration in the automotive industry. In order to create an as pleasant driving experience as possible for the driver, NVH should be minimized. One of the sources of NVH comes from the transmission due to the synchronization process.

  3. 12. Conceptual Dynamic Analysis of a Vehicle Body

    University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Author : Björn Pedersen; [2018]
    Keywords : Technology and Engineering;

    Abstract : The noise, vibration and harshness (NVH) and body dynamic performance of automotive vehicles is highly dependent of the components included in the body structure and compartment, since they add mass, stiffness and damping to the overall structure. Today, the noise levels in the compartment are predicted using complex and detailed computational models during both early and late stages of the vehicle development process. READ MORE

  5. 14. Investigation on Road Noise Transmission through Steering System

    University essay from KTH/MWL Marcus Wallenberg Laboratoriet

    Author : Yuan Xie; [2017]
    Keywords : Blocked force method; vehicle NVH test; coupled system;

    Abstract : 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. READ MORE

  6. 15. Incorporation of Manual Gearshifter

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Kong Phan; Carlos Rojas Tena; [2016]
    Keywords : ;

    Abstract : Syftet med projektet var att undersöka huruvida det var möjligt att integrera det manuella spakstället i Volvo Personvagnars modell, S90. Projektet fokuserade på en integrering utav spakställshuset i tunnelkonsolstrukturen då den nuvarande lösningen är onödigt stor och hämmar för andra potentiella funktioner. READ MORE
