...Jin Yang; Tengjiao Lin; Lidong Jiang This paper presents a novel windage power loss (WPL) measurement method for the meshing herringbone gear pair. First, the WPL test rig of the herringbone gear pair is put up, and then the measurement sequence of WPL is described. Second, the WPL of different...

... successfully for years, but accurate dynamic measurement has still not been achieved. Methods using pressure-sensitive films and controlled air flow have been employed, but both are limited. The work described in this paper has enabled, for the first time, the measurement of a dynamic wheel/rail contact patch...

... ability to predict the influence of such a pocket (with and without oil injection) on the pressure distribution and oil film thickness. Measurements of the distribution of pressure and oil film thickness are presented for tilting-pad thrust bearing pads of ∼ 100 cm 2 surface area. Two pads are measured...
