Abstract

The invention discloses an engine rotor blade dynamic signal output method based on a digital board card. The method comprises the steps: receiving a parameter setting instruction sent by a user, and setting a parameter value of a blade dynamic signal according to the parameter setting instruction, wherein the blade dynamic signal at least comprises a blade rotating speed signal, a blade tip position signal and a blade tip position change signal; according to set parameter value, automatically generating a blade dynamic signal through signal processing software; and outputting the blade dynamic signal through an I/O port of a digital board card. According to the invention, in a laboratory environment, signal processing software is utilized to generate signal waveforms, a digital board card is utilized to simulate engine rotor dynamic signals, development and debugging of an engine rotor dynamic signal acquisition and analysis system can be carried out without building a physical tester, the research and test cost is greatly reduced, and the research and development period is shortened.

Description

technical field [0001] The invention belongs to the technical field of rotor blade measurement, in particular to a method and equipment for outputting dynamic signals of engine rotor blades based on a digital board. Background technique [0002] The dynamic parameters of high-speed rotating rotor blades in industrial sites are very important to ensure the operation safety and work efficiency of large rotating equipment. Blade dynamic parameters such as blade vibration and blade tip clearance can provide intuitive evidence for judging rotor operating status and fault characteristics, and have practical theoretical and application value for improving the development level of large rotating equipment and verifying design performance parameters. Based on practical application requirements, blade vibration and blade tip clearance non-contact sensors for detecting blade dynamic parameters are produced, collectively referred to as blade tip sensors. Blade tip sensors include but ar...
