同根派生

An engineering calculation method of spot weld fatigue life prediction is introduced.
摘要介紹一種焊點(diǎn)疲勞壽命預(yù)測(cè)的工程計(jì)算方法。
And the draws of the stress, the whole life and the spot weld life of the crossmember are got after the analysis.
應(yīng)用有限元分析法對(duì)副車(chē)架的疲勞臺(tái)架試驗(yàn)進(jìn)行強(qiáng)度和疲勞分析,得到副車(chē)架的應(yīng)力分布圖、副車(chē)架本體壽命云圖和焊點(diǎn)壽命云圖。
In this estimator, the ANN is to realize the mapping characteristics from dynamic resistance to spot weld mecnanical proterty.
在此估測(cè)器中，經(jīng)訓(xùn)練的神經(jīng)元網(wǎng)絡(luò)將用于描述動(dòng)態(tài)電阻曲線與焊點(diǎn)力學(xué)性能的映射關(guān)系。
Strength of resistance spot weld is determined by the physical attributes of weldment including material and geometric issues.
電阻點(diǎn)焊接頭的焊接強(qiáng)度由母材和熔核的材料屬性及幾何特征決定。
The element selection,gridding, the finite element model of spot weld, loading and resolution are also discussed andthe APDL program is wrote.
對(duì)單元選擇，網(wǎng)格劃分，焊接關(guān)系的模擬以及加載求解做了介紹，并使用ANSYS提供的參數(shù)化編程語(yǔ)言編制了程序。
