Nonlinear analysis on constraint forces and space configuration of flexible pipe
The nonlinear iteration method of compelling displacement of boundary support was presented, combined with the nonlinear element method of space beam and Newton-Raphson nonlinear iteration, which can succeed flexibly in finding equilibrium configuration under complicated external loads. The relationship between space configuration of flexible pipe, constraint forces and active load by mining machine was studied. The result shows that the computing method is important to engineering.
