sine series

基本解释

The selected displacement functions of the finite strip method suggested in this paber art functions iterated by sine series and polynomial.
本文用正弦级数与多项式迭加作为位移函数。把有限条单元的端部角点视为节点，并把它们的位移作为未知待定参数。
The general analytic solutions satisfy the boundary conditions and the conditions at the corner points. The unsolved coefficients are worked out by the sine series method.
将一般解析解代入边界条件，用正弦数加角点条件的方法确定待求系数。
In this paper, sine series and polynomial beam functions are derived. They can satisfy various boundary conditions of beams such as the simply supported ends, fixed ends and free end.
本文推导了正弦级数与多项式的梁函数，它可以满足梁的简支、固定、自由等各种边界条件。
