介绍了用脉冲激振进行飞行颤振试验时的数据处理方法及软件研制。讨论了数据预处理方法和时域、频域参数识别方法。证明了时域和频域方法理论上是等价的，但实际应用中，因频域方法可选频段拟合，识别结果比时域方法好。仿真计算和实际应用结果表明该方法和软件是有效的。
The data processing method and software development of flutter test with pulse excitation are introduced. The methods of data preprocessing and time domain and frequency domain parameter identification are discussed. It is proved that the time-domain and frequency-domain methods are theoretically equivalent, but in practical applications, the identification results are better than the time-domain methods due to the frequency bands fitting in the optional frequency bands. Simulation results and practical application show that the method and software are effective.
