公司自主研發的「 180不銹鋼無縫彎頭」 ，被評為國家級新產品「高壓加氫不銹鋼急彎彎管」 99年通過省部級技術鑒定，填補了「高壓臨氫火焰直接加熱急彎彎管」工藝技術的國內空白，榮獲地市科技進步二三等獎，被中國國際貿易促進委員會及法國科技質量監督評價委員會向歐盟市場推薦為高科技產品 -
Based on the theory of thin - walled curved bar, reasonable hypothesized a third - ord parabolic curve, the paper adoptes variational method on energy, taking the coupled relationship of the effect of curvature radius, bend, torsion and shear - lag into consideration, establishes the elastic governing differential equation and boundary conditions for thin - walled curved box girders, which set the foundation of theoretical analysis of shear - lag effect in thin - walled curved box girders
摘要文章以薄壁曲桿理論為基礎，合理地假設了三個剪力滯翹曲位移函數，應用能量變分法推導出考慮曲率半徑影響、彎、扭、剪力滯耦合的曲線箱梁彈性控制微分方程及其邊界條件，為薄壁大麴率箱梁剪滯效應建立了理論分析基礎。
