正沖擊響應譜
英文
positive shock response spectrum-
The method to get the parameters for each basic waveform was given by choosing the sine window function waveform as the basic waveform, and based on the srs time - history synthesis principle
依據沖擊響應譜時域合成的一般原則,選擇合成小波中的正弦窗波作為基本波形,給出了確定各基本波形的波形參數的方法。Positive shock response spectrum
正沖擊響應譜On the basis of previous work, we developed a new data processing system by use of dsp & oop. the new system overcame the problems existed in the old data processing system successfully, such as the bug which cause program dead loop when the data is too long, and the frequency leak due to principle limit of fft filter. in addition, we eliminated the measurement error brought on by phase warp
我們在前人的工作基礎上,利用現代數字信號處理技術和面向對象的軟體開發技術,統一了彈上黑匣子數據處理系統的操作平臺,完善了轉速、掃描角測試數據處理系統,修正了原有處理程序中的因數據長度過長而導致程序死鎖的bug ;利用有限沖擊響應( fir )濾波器,在濾去噪聲的同時,有效地解決了矩形窗fft濾波的頻譜泄漏問題;另外還解決了因相位偏差而導致的測試誤差。
