解釋
時頻圖-
It really provides convenience to evaluate and optimize the design result. 3 ) vibration analysis has been fulfilled by calling some math libraries and graphic libraries in matlab to plot graphics such as velocity - time, displacement - velocity, step response, impulse response, gain - frequency and phase - frequency. we can know the capabilities of the spring system from the graphics
3 、在matlab環境下調用相應的數學函數庫和圖形庫對設計的彈簧進行分析,繪制彈簧加載后系統的速度-時間響應曲線、速度-位移響應曲線、階躍響應曲線、脈沖響應曲線、增益-頻率響應曲線和相角-頻率響應曲線,根據曲線來分析系統的各項性能。 -
As another application instance, a subsystem monitoring ultra - high frequency partial discharge of transformer is developed, which can analyse, process, plot time - domain pd data and demodulated pd data, besides, it also has such discharge type recognition function as spectrum calculation and auto correlation
作為另一應用實例,研製了變壓器超高頻局放監測子系統,此系統具有分析、處理、顯示超高頻時域波形及其包絡線波形數據的功能,還具有用於放電模式識別的時域波形及其包絡線波形的頻譜計算和自相關處理等功能。
