中文拼音 [jǔxíngbōxiǎngyīng]
矩形波響應
英文
square wave response-
As one part of the work, the induced current on perfect conductor surface is computed with mom method and graphed by origin. the factors, such as choice of basis function and sliced mounts of one cell, which affect solution accuracy are summarized. all of these provide a good basis for the latter computation of array scattering field
其中第一部分工作從電場積分方程出發，利用矩量法計算了理想導體貼片上的感應電流，進而得到平面陣列和曲面陣列的散射場，研究了陣列單元尺寸、排布形式和入射波的角度，以及曲面陣列的陣面形狀等因素對陣列散射場的影響規律。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。After comparing three form ( rectangle, saw and sine wave ) of excitation force, the conclusion is drawed that the sine wave is much better than the other two waveforms. finally, multi - seedling virtual prototype is studied
另外，對比分析三種波形（矩形波、正弦波及鋸齒波）激振力對振動系統的影響，發現採用正弦波激振力對振動系統沖擊較小，應優先考慮使用。
