Examples
- Considering the fuzziness of some boundary conditions enviroment media , and especially some loads in the engineering structure analysis , we go further into the computation based on the dynamic problem of fuzzy finite element ( ffe ) , study further and systematically the analysis and solution . the principle of fuzzy minimum potential energy is established , and the balance equation of fuzzy finite element is reasoned by making fuzzy variation . at the same time , the dynamic balance equation of stochastic by making stochastic variation ， also the fuzzy stochastic dynamic balance equation is deduced . based the theory that the degree of the fuzziness and probability can be measured , in the other word , by using the concept of fuzzy entropy and entropy , pure fuzzy dynamic structure is given through transforming the probability to fuzziness . for the fuzzy parameter can be regarded as a fuzzy vector with dimensions , the structure ' s eigenvalue , by the theory of small parameter
建立了模糊瞬时最小势能原理，运用模糊变分原理导出了模糊有限元动力平衡方程；同时，利用随机变分原理导出了动力问题的随机有限元方程，同时得到了模糊随机动力问题的有限元平衡方程。根据模糊度和概率度可以度量的原理，即利用模糊熵和概率熵的概念，把结构的随机性等效地转化为结构的模糊性，得到纯粹模糊性的动力结构。把结构所具有的模糊参数看作一个维的模糊向量，利用小参数摄动原理，把结构的特征值，特征向量和位移都在模糊向量的均值处进行泰勒展开，得到一组递归方程，即可以求得结构的模糊特征值，特征向量和模糊位移。
