Using the correlative program, buckling analysis was made with plates, shells and portal frame made of plates. 應(yīng)用所編制的程序，進(jìn)行了平板、曲殼以及板式門架的雙重非線性屈曲分析。
Thus, the frameInc variable is defined to provide the proper frame increment between 1 and (Portal Frame/2) in the blended distortion zone. 因而，變量 frameInc 的定義是提供混合失真區(qū)域內(nèi)恰當(dāng)?shù)膸g步長，取值 介于 1 和 (門幀/2) 之間。
The brake wheel is a key part of portal frame crane, and its earlier failure and heat treatment defect during manufacture and use is the key factor, which affects the cost and efficiency. 制動輪是門座式起重機(jī)制動裝置的關(guān)鍵零件，制動輪在生產(chǎn)制造和使用過程中的早期失效及熱處理缺陷是影響生產(chǎn)成本及效率的重要因素。
