Abstract
Durability testing of automotive transmission components under rated load conditions usually requires costly and large test rigs. In order to avoid this disadvantage the power loop test rig has been designed and realized. A design with two continuously variable transmission variators and one drive motor saves space and costs. An unconventional servo hydraulic actuation system is used to control clamping forces and transmission ratio. A physical model of the test rig is realized and a controller is designed which meets the requirements for durability testing. Experimental results show the validation of the model and functional measurements are presented.
