Research on Racing Loss of a High-Power Hydraulic Retarder

This paper aims at the requirement of tracklayer gearing controlling racing power loss (for short racing loss), analyzed mechanism of generating racing loss of a high-power hydraulic retarder. By adding different number of baffle-plate equipment, racing loss was reduced. Using CFD technology, this paper studied contrastively the racing loss of hydraulic retarder in different condition, and compared with experiment result. The result indicated that the racing loss reduced obviously after fixing baffle-plate equipment, and the CFD simulation results agree well with the experimental results.
