英文
bridge processing unit-
The purpose of this thesis is to use artificial neural networks ( ann ) to identify the aerodynamic parameters. first introduced in this paper is the basic theory of ann and wind engineering in bridge, then ann is presented to identify the aerodynamic derivatives of ideal thin plate. a back - propagation ( bp ) ann is established and trained for many times to contrast the influences of some factors on the prediction results
首先對人工神經網路和橋梁風工程的基本理論作了簡單的介紹,接著採用人工神經網路識別了理想薄平板的氣動導數,並分析了數據處理方式、隱層單元數、訓練次數、隨機賦值次數、樣本數量對訓練結果的影響,討論了訓練的穩定性。Special grids is adopted for solid model of conical roller bearings by applying for three - dimensional solid and contact elements, aiming at its characteristic, stress and load distribution of elastic contact problems. finite element model built in the paper is fit for objective practice, with flexible - flexible contact bodies and surfaces - surfaces contact mode
本文針對汽車后橋傳動錐軸承的接觸彈性變形特點、接觸應力及負荷分佈規律,採用三維實體單元及三維接觸單元對圓錐滾子軸承實體模型進行特殊的有限元網格劃分,將接觸單元按柔體一柔體處理,採用面一面接觸分析模式,建立了符合實際的有限元模型。
