Aircraft Hydraulic System Dynamic Analysis. Volume III. Frequency Response (HSFR) Computer Program User Manual.

摘要

The hydraulic system frequency response (HSFR) computer program was developed to simulate the dynamic response of a hydraulic system to the acoustic noise generated by the pump. Detailed instructions for modeling the system pump,lines,and components,and for using the program are presented. For a selected system pressure,temperature,flow,and pump speed range,the program calculates the pulsation pressure and energy levels generated by the pump. It predicts the amplitude and location of the resulting acoustical standing waves,and how these waves are transmitted and attenuated throughout the hydraulic system. The program may be used for acoustical analysis in the pressure side or both the pressure and return sides of the hydraulic system.
