许多工程系统定义不明确且不准确，尤其是在初步设计阶段。有必要开发模糊有限元方法来对涉及模糊性的系统进行设计分析。提出了一种使用模糊有限元方法 (FEM) 对不精确定义的系统进行振动分析的方法。提出了实施该方法的数值程序。考虑两个数值例子来说明该方法的计算有效性。这项工作代表了在涉及动力学的模糊有限元分析领域的首次尝试。 (C) 1997 Elsevier Science B.V.
Many engineering systems are ill-defined and imprecisely known, especially in the preliminary design phase. It becomes necessary to develop fuzzy finite-element approaches for the design analysis of systems involving vagueness. A methodology using the fuzzy finite-element method (FEM) is proposed for vibration analysis of imprecisely defined systems. Numerical procedures to implement the methodology are presented. Two numerical examples are considered to illustrate the computational effectiveness of the approach. This work represents the first attempt made in the field of fuzzy finite-element analysis involving dynamics. (C) 1997 Elsevier Science B.V.
