Calculation and Analysis of Traction Infinitely Variable Transmission

2011 Second International Conference on Digital Manufacturing & Automation, 2011
Traction oil film thickness calculation is done on a kind of continuous velocity transmission which is named traction infinitely variable transmission (TIVT). It is proved that transmission type of TIVT is traction drive rather than friction drive through design on roughness, material of parts and traction oil.

Fatigue life prediction of IGBT module for metro vehicle traction converter based on traction calculation

2015 IEEE 11th International Conference on Power Electronics and Drive Systems, 2015
Metro vehicles start and stop frequently, which leads to complex fluctuation of IGBT module's junction temperature and induces fatigue that causes the failure of IGBT module. In order to predict the fatigue life of IGBT module, theory and method for calculating train traction, loss, transient temperature and fatigue life were analyzed, and ...
