基于非概率可靠性灵敏度方法的研究

Research on reliability sensitivity method based on non-probability

结构灵敏度分析的非概率法克服了概率可靠性灵敏度所存在的缺陷,可以在不用进行求导数运算的条件下,通过区间运算即可获得结构响应(或其性能)随结构参数(或设计变量)的变化情况。文中通过数值算例表明了用非概率法进行结构灵敏度分析的可行性、有效性和简便性。

Non-probability methods of structural sensitivity a- nalysis overcome the shortcoming of probability reliability sensitivi- tyo Without the use of operations of partial derivatives, the method allows information on the response （or performance ） of the structure to be obtained from the structural parameters （or design variables）. In this paper, numerical examples were used to illustrate the feasibility, effectiveness and convenience of non-probability methods.
