【Abstract】 By applying the contacting nonlinear finite element theory this paper carried out a virtual design on complex supporting structure. Applications of contacting nonlinear finite element theory in practical issues were being probed.A study on the establishment of finite element model of complex structure was carried out.The distribution law of displacement and stress under different forms of structure and working conditions and the main factors that affecting displacements in every direction and strength of support were being analyzed and obtained.These provides theoretical basis for the actual application of contacting nonlinear finite element theory and the further improvement on the supporting structure in the collision zone.更多还原
