燃气阀响应时间的光学测量方法
Optical measurement method for response time of gas valve
摘要
Abstract
For response time measurement of gas valve, the optical method which uses laser to illuminate plume,analyze the light intensity variation,and determine response time was proposed.The measuring test-bed of single valve was designed and applied to measure the response time of opening and shutting of gas valve.The light intensity variation was obtained and analyzed by band-pass filtering, and the response time was measured rapidly and non-intrusively.Furthermore,the measurement validity of optical method is validated by comparing with the pressure and thrust sensor conventional measurements.It provides a non-intrusive method for high dynamic characteristic measurement for gas valves关键词
