  1. In view of this situation this article has conducted research to the design of metallurgy auxiliary biography with the frequency conversion table electrical machinery first multianalysis to the frequency changer and the frequency conversion table electrical machinery movement characteristic is carried out, the voltage waveform harmonious which the frequency changer outputs is big, attacks in a big way, and the voltage climbing rate reaches as high as 6600v / mu s which is 20 times ordinary sine alternating voltage, the rolling mill auxiliary biography table set the extremely strict request to the electrical machinery ; its movement frequency is very low, rate frequency in 8 - 20hz ; the velocity modulation scope is wide, the lowest movement frequency lowers to 1hz, and the starting number of times is quite frequently, each hour reaches as high as 600 - 800 time, the impact shoulders in a big way, the overload capacity request is high

    針對這一情況本文對冶金輔傳用變頻輥道電機的設計進行了系統研究。首先對變頻器和變頻輥道電機的運行特性進行詳細分析，變頻器輸出的電壓波形諧波大，沖擊大，電壓上升率高達6600v / s ，是普通正弦交流電壓的20倍;軋機輔傳輥道對電機提出了十分嚴格的要求:其運行頻率很低，額定頻率在8 - 20hz ;調速范圍寬，最低運行頻率低到0 . 5hz ，起動次數相當頻繁，每小時高達600 - 800次，沖擊負荷大，過載能力要求較高。
  2. 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。
  3. With the help of the fuzzy algorithm in the controller, the output voltage of the power can be controlled and the voltage wave can be adjusted to be symmetric so that the lift can stop accurately, and the shock can be decreased

    實驗結果顯示，採用這種模糊控制的環流變換器的電壓輸出性能得到大幅改善，波形對稱且非常接近正弦形，能夠保證礦井提升機停位準確，減少沖擊。
  4. Effects of hard - nonlinear cushion for drop shock machine to simulation of half - sine waveform

    跌落沖擊機墊層的硬非線性對半正弦波模擬的影響
  5. Methods for the calibration of vibration and shock pick - ups. comparison secondary vibration calibration by sinusoidal excitation

    振動與沖擊傳感器的校準方法正弦激勵法校準
  6. Adopting relatively simple mechanical model and predigested boundary condition and taking a straight bar applied one end with an semi - sine impulse to simulate the rigid target impacted by a projectile as an example, the relation between the stress wave propagation and acceleration of projectile has been analyzed by theoretical deduction and computer simulation

    摘要採用較為簡單的力學模型和簡化的邊界條件，以直桿一端施加一半正弦載荷脈沖和模擬彈體沖擊剛性靶為例，用理論推導和計算機模擬的方法分析應力波傳播和彈體加速度的關系。
  7. 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。
