This study deals with the optimisation of hybrid composite drive shafts operating at subcritical or supercritical speeds, using a genetic algorithm. A formulation for the flexural vibrations of a composite drive shaft mounted on viscoelastic supports including shear effects is developed. In particular, an analytic stability criterion is developed to ensure the integrity of the system in the sup...

This article describes the design of a traction control system in an electric Formula Student vehicle. In many race applications the accelerator pedal is difficult to control for an in-experienced driver, especially in the case of electric vehicles, where a large torque is available from standstill. A 3-DOF driveline model is used in combination with a 7-DOF vehicle model and a non-linear tyre ...

In powertrain analysis, simulation of driveline models are standard tools, where efficient and accurate simulations are important features of the models. One input signal with high impact on the accuracy is the road slope. Here it is found that the amplitude discretization in production road-slope sensors can excite vehicle shuffle dynamics in the model, which is not present in the real vehicle...

For enhancement of the drivability and lifetime components, reduction in vehicle driveline oscillations has been addressed by advanced active control algorithms. However, most existing works involve subjective determination their critical controller parameters, imposing heavy adjustment tasks on designers. This research presents an efficient tuning algorithm model-based vibration that explicitl...

IntroductionDriveline infections in patients with a left ventricular assist device (LVAD) are feared due to significant morbidity and mortality. There might be great potential preventive measures at home.Case ReportA 54-year old patient showed deep LVAD (HeartMate III) driveline infection by Pseudomonas aeruginosa shortly after his first shower home. Despite 6 weeks of antibiotics (piperacillin...
