运用数值方法研究固定边界条件下，超临界速度范围内的轴向运动梁横向与径向耦合平面的静态平衡位形分岔行为，其中轴向运动梁的静态平衡位形包括直线形状的0解，以及随传输速度分岔得到的曲线形状的非平凡分岔解.在梁的两端固定的边界条件下，运用有限差分法对轴向运动梁平面耦合非线性方程以及对应于非线性平面耦合方程的静态平衡方程作数值解.以铜材料的梁为例，数值求解轴向运动梁耦合平面的静平衡非平凡解，并仿真分析了系统参数对非平凡分岔解的影响.

Equilibria of axially moving beams transversely and longitudinally coupled with the fixed boundary conditions are numerically studied in the supercritical transport speed ranges. In the supercritical regime, the pattern of equilibria consists of the straight configuration and of non-trivial solutions that bifurcate with transport speed. The numerical schemes are presented for the governing equation of coupled planar and the corresponding static equilibrium equation for non-trivial equilibrium solutions via the finite difference method under the fixed boundary conditions. A copper beam is treated as example to demonstrate the non-trivial equilibrium solutions. Numerical results indicate that the equilibrium of the coupled planar with the changing parameters.
