    摘要:

    為了對車用液力減速器葉片數(shù)目進行參數(shù)優(yōu)化，建立了液力減速器葉柵參數(shù)三維集成優(yōu)化仿真平臺。以葉片數(shù)為設(shè)計變量，三維CFD計算作為求解器進行DOE試驗設(shè)計，并根據(jù)試驗樣本結(jié)果構(gòu)建RSM模型進行優(yōu)化，得到液力減速器動、定輪最優(yōu)葉片數(shù)。就葉片數(shù)對液力減速器內(nèi)流場特性、制動外特性的影響進行了分析，并結(jié)合試驗數(shù)據(jù)對優(yōu)化前、后緩速制動性能進行了對比。結(jié)果表明，優(yōu)化仿真平臺精度較高，結(jié)果可信。優(yōu)化后的液力減速器緩速制動性能顯著提高。

    Abstract:

    To optimize the parameters of blade numbers of vehicular hydraulic retarder, a 3-D integrated optimization platform was established. The brake torque of hydraulic retarder was calculated with CFD solver and DOE technique of design variable. With DOE results, the RSM model was built to get the optimum parameters. The relationship of internal flow field and brake performance with the varying blade numbers was analyzed and concluded. Comparison of experimental data and simulation results before and after the optimization showed that the brake performance of hydraulic retarder with the optimum parameters was improved observably, and the 3-D integrated optimization platform was accurate and reliable.
