摘要
讨论了一种液压阀实验建模方法 ,研究了瞬态压力发生器的工作特性、相应参数的测量和数字信号处理 ,以及使用实验数据建立数学模型的方法。
A method of experimental modeling for hydraulic valves is proposed in the paper. The dynamic properties of a transient pressure generator generating an approximately impulsive flow used as the excitation of the valve being in experiment, the measurement of related parameters and the processing of corresponding digital signals are studied in detail. In addition, a method of dynamic calibration for pressure transducers is also discussed.
