| 摘 要： | 根据柔索应变与位移非线性几何关系以及自重作用与温度影响下的平衡方程,采用欧拉坐标系统精确地求得了各点位移和张力的一般解.由柔索的非线性变形问题建立的非线性代数方程组应用改进Powell混合算法编制的高精度DNEQNF程序直接进行求解.算例中对柔索两端点在同一水平线上承受自重或集中力两种情形进行了计算,并与其他学者用不同...

| Abstract: | On the basis of nonlinear geometric relation between strain and displacement for flexible,the equilibrium equation under self-weight and influence of temperature,an analytical solution of displacement and tension for every point defined in eulerian coordinate system is obtained accurately.To solve the nonlinear algebraic equation caused by nonlinear deformation problem of flexible cable,the modified powell hybrid algorithm with high precision routine DNEQNF of fortran can be used directly.For example,a flex... |
