利用突变理论分析工程事故中压杆失稳问题

Using catastrophe theory analysis the bending pole question

从压杆稳定的基本体系出发,利用突变理论的基本公式推导出压杆失稳的尖点突变模型,并且利用算例对推导出的尖点突变模型进行验证,得出的结论证明了利用突变理论分析压杆失稳问题的可行性。

Embarked from the bending pole the stable basic system,inferred using the catastrophe theory fundamental formula the bending pole loses the steady cusp catastrophe model and used calculated the example to inferred cusp catastrophe model to carry on the confirmation,obtained the conclusion had proven the use catastrophe theory analysis flexure question feasibility.
