Prediction of losses in belt-type continuously variable transmission due to sliding between belt and disc

Poll, G.; Kruse, T.; Meyer, C. (London : SAGE Publications Ltd., 2006)

The efficiency of belt-type continuously variable transmission (CVT) - apart from the power consumption of auxiliary systems such as hydraulics - predominantly depends on the energy dissipated during sliding at the belt-disc ...
Proposals for a practical calibration method for mechanical torque measurement on the wind turbine drive train under test on a test bench

Zhang, Hongkun; Wenske, Jan; Reuter, Andreas; Neshati, Mohsen (Chichester : Wiley, 2020)

The mechanical torque input into the wind turbine drive train is a very useful measurement for tests performed on a test bench. To ensure the accuracy and the reliability, an accurate calibration of the torque measurement ...
Rapid prototyping of reflectors for vehicle lighting using laser activated remote phosphor

Lachmayer, Roland; Kloppenburg, Gerolf; Wolf, Alexander (Bellingham, Wash. : SPIE, 2015)

Bright white light sources are of significant importance for automotive front lighting systems. Todays upper class vehicles mainly use HID or LED as light source. As a further step in this development laser diode based ...
