中文拼音 [zhòngxíngdiàogǎn]
重型吊桿
英文
heavy derrick boom-
Destabilization style of an arcuated built - up system bridge, influence of nonconservative force of hanger rods, comparative between stress value in construction stage and stress value in finished bridge stage, stability coefficients in bridge code, these are discussed deep
著重對失穩類型、橫撐在穩定中所起的作用、吊桿非保向力的作用以及施工階段的應力和成橋階段應力的比較、規范中穩定安全系數的規定進行探討。Can you provide original mtc, if you can please send me a copy of mtc ( h - beam. i - beam, plate ) by ? email in pdf format
能否把mtc （可能是桅桿型起重機吧）的原始數據提供給我，包括h型吊臂、 i型吊臂、以及平板式吊臂，如果有這個數據的話，請用pdf格式發電子郵件給我。It builds a physical model according to hoisting capacity, lifting angle and structural stabiliy, theory, solves the problem of function relationships among lifting capacity, lifting angle, boom weight, boom dimension and deduces the natural boundary condition of design parameters, providing a new way to determine crane design parameters
摘要將起重量和起吊幅度為基本設計依據，以壓桿穩定理論為分析基礎，結合專業知識，建立物理模型，解決了起重量、起吊幅度與吊臂質量、吊臂主要參數之間的函數關系的難題，首次確定出設計參數的自然邊界條件，為起重機設計者提供了確定設計參數的新方法和科學依據，具有開創意義。Derrick boom headfittings - fixed type
起重機吊桿的頂部配件.固定型For the cranes which arm angle and length is alterable, its utmost hoist competence is changeable. so we must found the characteristic curve math model of the crane. then the plc programme can provide protection for the crane working according to the math model
對于臂桿角度和長度可變的起重機而言，其起吊重量極限值是變化的，這就要求事先建立這類起重機的起重特性曲線的數學模型，然後再讓plc程序按照給定的數學模型對起重機進行安全作業保護。Heavy lift derrick
