弦鋸 的英文怎麼說
中文拼音 [xiánjū]-
First, the system operation conditions that include three input types ( square, sinuous and triangle ) with different frequencies ( l / 250hz, l / 5hz and 1hz ) are discussed. in fault detection processes, we construct 4 three - layer bp neural networks to learn the normal states of the system. the outputs of trained neural networks are as the estimate values of the sensors
本文詳細研究了在這種情況下的故障診斷問題，針對某液壓系統，分析了系統在方波輸入、正弦輸入、鋸齒波輸入下，分別在正常工作頻率、極限工作頻率以及接近極限工作頻率等9種工作狀態的特性，以及在這9種工作狀態下，運用神經網路觀測器進行傳感器故障診斷研究。Passive suspension, pid control semi - active suspension and neural network control semi - active suspension are researched by simulation. white noise, sine wave and sawtooth wave are used for excitation. the root mean square value of vehicle body acceleration, suspension displacement and vehicle wheel load are analyzed
在模擬研究中，路面激勵取為白噪聲、正弦波和鋸齒波，懸架類型採用被動懸架、 pid控制半主動懸架、神經網路控制半主動懸架三種。( 2 ) the properties of displacement measurement based on self - mixing interference are mathematically analyzed. first, how the external phase influences upon the output frequency, intensity, power and line - width is discussed. then, the output signal ' s properties modulated by four waves, including sine wave, square wave, triangular wave and saw tooth wave, is discussed
（ 2 ）通過數值分析討論了自混合干涉位移測量系統的基本特性，包括外腔相位對輸出光頻、輸出強度、輸出功率、譜線寬度的影響，以及正弦波、方波、三角波、鋸齒波調制反射體位移時輸出信號的特點。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。分享友人
