  1. 1. Advances In Heavy Vehicle Dynamics with Focus on Engine Mounts and Individual Front Suspension

    Författare :Hoda Yarmohamadi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vibration isolation; semi-active damper; handling; heavy vehicle; individual front suspension; nonlinear dynamic stiffness and damping; kinematics; adaptronic mounting system; engine mount; comfort;

    Sammanfattning : The main objective of the research presented in this thesis is to enhance driver comfort and handling of a heavy truck that in turn leads to better vehicle safety and stability. The focus has been put on studying two suspension systems of the truck, engine and front axle suspensions, due to their significant impact on the dynamic performance of the vehicle. LÄS MER

  3. 2. Development of Separation Phenomena on a Passenger Car

    Författare :Sabine Bonitz; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; complex flows; vortex formation; vehicle aerodynamics; flow separation; limiting streamlines; crossflow separation;

    Sammanfattning : The general shape of a vehicle influences its aerodynamic performance through separation phenomena and flow structure development. Since these flow characteristics have a direct influence on the energy efficiency, safety and comfort, it is essential to study their formation and evolution into the freestream. LÄS MER

  5. 4. Mathematical Simulation of Vehicle-Pedestrian Collisions: Influence of Vehicle Impact Speed and Front-End Structure on the Dynamic Responses of Child and Adult Pedestrians

    Författare :Xuejun Liu; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; child pedestrian; impact biomechanics; mathematical model; vehicle front-end structure; safety countermeasure; impact speed; parametric study; scaling method;

    Sammanfattning : The development of effective countermeasures for pedestrian protection requires an understanding of how the impact speed and front-end design of the vehicle influence the injury risks of pedestrians. Because of the high involvement of children in pedestrian accidents, there is also a need for child pedestrian mathematical models. LÄS MER

  7. 5. Cost and weight effective composite design of automotive body structures

    Författare :Per Mårtensson; Dan Zenkert; Malin Åkermo; Lars Nyborg; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Farkostteknik; Vehicle and Maritime Engineering;

    Sammanfattning : The automotive industry stands in front of a great challenge, to decrease its impact on the environment. One important part in succeeding with this is to decrease the structural weight of the body structure and by that the fuel consumption or the required battery power. LÄS MER
