摘要
在自然曲线坐标系给出了空间曲杆的控制方程，求得其静定问题解析通解，以此为基础构造曲杆元广义位移模式，得到了一种收敛的、精度高的曲杆单元。
A system of governing equations for spatially curved rods are derived in natural coordinate,and an analytic solution to the statically determinate problem is given.Based on the solution,a generalized displacement model for element of curved bars is developed,which is convergent and accurate.
