There are functions such as drawing the chart of amplitude - frequency and phase - frequency, calculating and displaying the highest peak value, the total sum of amplitude and the effective line - breadth of the signal in the program. so an effective technical means is supplied for the analysis of ultrasonic signal
軟體系統具有幅頻圖及相頻圖的繪制、最高峰值、諧波系數及有效譜寬度的計算及顯示等功能,從而為超聲信號的頻譜分析提供了極其有效的技術手段。After analyzing the traditional methods of generating exciting signals in vibration control system of electrodynamic ( electrohydraulic ) shaker, a new method of adjusting the skewness and kurtosis of exciting signals by second phase modulation is proposed. based on this method, a new algorithm for generating super - gaussian and quasi - random vibration exciting signals with specified psd, skewness and kurtosis is proposed. simulation and experimental results validate the algorithm
2 .通過分析目前電動(液)振動臺數字式隨機振動控制系統中廣泛採用的激勵信號生成原理,在其基礎上提出了一種通過二次相位調制來控制激勵信號峭度值和偏斜度值的方法,分別得到了頻譜可控的對稱和非對稱分佈超高斯偽隨機激勵信號生成演算法,並進行了數值模擬和試驗驗證,為研究頻譜可控的超高斯真隨機激勵信號生成技術奠定了基礎。
