| 摘 要： | 本文对隔离气压式蓄能器频率特性测试方法进行了研究.针对不同的测试指标,提出了不同的测试方法.一种是阀控液压缸驱动加振液压缸的测试装置,该试验台既能测导纳或阻抗,也能测压力传递函数.另一种是伺服阀直接激励试验装置,该试验台专门用于压力传递函数测试,试验装置、试验方法都较简单.两种测试方法所得结果与理论值基本吻合.

| Abstract: | The paper makes a research on the measurement of the frequency characteristics of the accumulator. Two measurement methods are used for different measurement indexes. In one system, the valve-controlled cylinder drives the exciting cylinder to measure admittance (or impedance) and pressure transfer function. In the other, the servo valve excites the aecumlator directly so that pressure transfer function can be measured, and the measurement device and its operation are simple. The results obtained from the two methods are close to the theoretical reculte |
