摘　　要：基于一维束流理论推导某车辆液力缓速器内腔压力数学模型,但试验结果表明了该理论的局限性。通过对试验数据进行统计分析,更深入地揭示了缓速器内腔压力的特性。尝试采用神经网络建模,获得了较好的外推效果,并进行了试验验证。A mathematical model for the internal pressure of hydraulic retarder is derived based on one-dimensional flow theory, but test results indicate the limitation of the theory. Through statistical analysis on test data, the characteristics of internal pressure are more deeply revealed. Modeling using artificial neural network is tried with a reasonable extrapolating result obtained, which is then verified by test.
