摘要
本文用函数φ,将双位移梁理论的两个基本方程简化为能适合于各种约束条件和载荷条件梁的一个基本方程,并应用简化后的方程,以三角级数作为试函数,用加权余量法求解正交各向异性复合材料双位移梁的挠度和转角。与其他计算方法相比,此法的计算过程被大大简化。
By a function Φ, two fundamental equations in double displacement theory are simplified into one applicable to beams under different restricted and load consitions , by which and taking trigonometrical series as trial function and using weighted residuals, street corner and deflection are solved of orthogonal anisotropic composite material beams with double displacement. Calculation is greatly simplified as compared with other solutions.
