Abstract
Aiming at the time history curve real⁃time display characteristic of dynamic signal in high sample rate during flight flutter test monitoring,real⁃time drawing of dynamic curve via TChart control under the circumstance of C++ Builder is in⁃troduced,the characteristics and choice criterion of the adopted control and algorithm are analysed in detail,and the relative program code is shown. In the algorithm,the flutter data is stored in digit group first,and then its time history curve is dis⁃played in real time by page turning mode in combination with Tchart control and Ttimer control. The practical application in flight flutter test monitoring shows that the algorithm can effectively display actual dynamic signal in real time,and meet the monitoring requirements. The algorithm can be also applied to the vibration monitoring system of power system.关键词
