1. Accelerated test for vehicle body durability basedon vehicle dynamics simulations using pseudodamage
Master-uppsats, KTH/FordonsdynamikSammanfattning : Vehicle body durability evaluation strongly relies on the possibility of testing areal prototype on different testing surfaces, such as proving grounds, test rigsand real roads. Although many efforts have been made to reduce time requiredfor testing, this still remains one of the main resource-demanding phases in avehicle development. LÄS MER
2. Heavy vehicles: Load variation and scatter
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : This master thesis studies accelerations recorded and stored onboard Scania trucks. From these accelerations, a general load (𝐹 = 𝑚∗ 𝑎) description is deduced. In the next step, an abstract number, ‘pseudo-damage’, representing the load’s fatigue damage potential is calculated.

3. Quantification and Implementation of Structural Damping in MBS Flexible Bodies
Master-uppsats, Lunds universitet/MekanikSammanfattning : In multi body simulation (MBS) using flexible bodies, damping is an important model input to be able to predict the response of a structure with sufficient precision. The purpose of this thesis has been to estimate the structural damping of an experimental setup and implement the estimated damping into MBS-models of the setup. LÄS MER
4. MBS-modelling of a heavy truck : Modelling and model validation
Master-uppsats, KTH/FordonsdynamikSammanfattning : As a result of the accelerating demands for faster development within the heavy vehicle industry, computer aided simulations have become a more important tool in the development process. Simulations can offer faster evaluation of loads acting on the vehicle and more cost effective fatigue life predictions than physical testing, since physical prototypes are not needed for load measurements or fatigue tests.
