4. Advances In Heavy Vehicle Dynamics with Focus on Engine Mounts and Individual Front Suspension
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
5. Towards active engine mounting systems for commercial vehicles: modeling and analysis
Sammanfattning : The vehicle engine mounting system, which consists of several mounts connecting the engine to the vehicle structure, not only supports the weight of the engine but also isolates the noise, vibration and the transmitted forces to the vehicle structure. At present conventional elastomeric mounts are widely used in engine mounting systems for commercial vehicles. LÄS MER
