摘要
应用接触非线性有限元理论,对复杂的支架结构进行了虚拟设计。探讨了接触非线性有限元理论在实际问题中的应用,对复杂结构有限元模型的建立进行了研究,分析并得到了不同的结构形式和工作状态下,位移和应力的分布规律,以及影响各方向位移和支架强度的主要因素,为接触非线性有限元理论的实际应用及对撞区支架结构进一步改进,提供了理论依据。
By applying the contacting nonlinear finite ele ment theory this paper carried out a virtual design on complex supporting structure. Applications of contacting nonlinear finiteelement 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 im provement on the supporting structure in the collision zone,
