Project Description


Project description:

Initial situation
The simulation program WTplus is being developed and widely used to compute the efficiency and heat balance of gearbox systems containing cylindrical and bevel gears by using current calculation models. The efficiency is determined by adding up load-dependent and no-load power losses of gears, bearings, seals and other rotating components. The calculation of the heat balance of the gearbox is based on the heat transfer between the single components, as well as heat dissipation to the environment. A suitable abstraction of the gearbox by nodal points is conducted for an efficient and accurate calculation of local temperatures using a thermal network model.

Student Tasks
Students take part in the development and validation of WTplus in the context of various gearing systems. Their individual tasks during the PREP are the development, improvement and extension of calculation models for bearing power losses and the subsequent validation of calculation results by measurements for various gearboxes.

Expected outcome
• Extended range of calculation models for bearing power losses
• Verification and validation of calculation models
• Improved quality of calculation program

Working hours per week planned:
