摘要利用普适开折定理研究了多重缺陷对音叉型结构临界载荷的影响。 By means of the theory of universal unfolding, the influence of multiimperfections upon the critical loads of pitchfork structures in engineering is analysed. The estimation formula for lower bounds on the increments of the critical loads that are caused by imperfections of the structures is given, and a simple and available numerical method for computing lower bounds is described.
