  1. This is a newly introduced slight shocking, direct driving centrifugal hyro - extractor. the electric locomotive on its base is semi - closed, internal ventilating, self cooling, weight adding and energy saving. the internal drum and rotational drum are istalled on the axel of the locomotive and drived directly, which effectively decreases energyloss, and simplifies therotation. acontrolling box is used in the machine to start through frequency conversion. and stop through resistance. the showing board shows the rotation speed and adjusts the speed and time. the featues of this machine areenergy saving, durable and repair infrequent. this machine is spcially used for cloth hydroectraction

    本機系最新引進直微震直驅式離心脫水機，它使用半封閉內通風自冷加重型專用節能電機裝于中間底座，內桶及轉鼓裝于電機軸而直接驅動之，有效地減小了多功能損耗，簡化了傳統的多級繁瑣轉動，本機配有一個電控箱機變頻起動，電阻剎車於一體面板有轉速顯示並可調速度及時間，該機特點省電、耐用、維修機會極少，本機適合布匹脫水使用。

  4. Secondly, two carbon fiber reinforced composite beams were fabricated, and their modal frequencies were measured by an experiment method. thirdly, delaminations were modeled by pairs of nodes with the same coordinates but different node numbers, while the modal frequencies of these beams with different delamination location and size were computed by an eas piezoelectric solid element. moreover, a novel method combining computational mechanics and neural network was demonstrated for composite health monitoring ; the first five flexure modal frequencies obtained by fem were modified by a primary revising approach and were used to train the neural network

    本文較全面地評述了神經網路的應用模型、改進演算法等，編制了bp神經網路程序：制備了纖維增強復合材料試件，並進行實驗模態分析；利用坐標相同、節點號不同的方法模擬脫層損傷，基於eas列式的壓電固體單元計算了不同脫層損傷情況下的頻率信息；針對基於實驗數據訓練神經網路存在樣本不足的缺陷，本文提出了利用有限元方法對含有脫層損傷的復合材料試件進行數值模擬，以前五階彎曲模態頻率構建訓練樣本的新思路，並提出了一種初步的計算值修正方法，以此構建神經網路的訓練樣本：將實驗模態分析的結果送入訓練好的神經網路進行預測，實現了對復合材料梁的脫層損傷的定位和損傷程度的評估。
