阐述了变量化分析的原理和理论模型 ,包括高阶灵敏度分析、基于泰勒级数近似展开式和迭代摄动的参数分析 ,以及兼顾精度和重分析效率的误差控制。以箱形盖板为具体算例 ,研究了变量化分析技术在机械结构快速设计中的作用和应用前景。

Abstrac: This paper exPOunded the principle of variatiOnalized analysis and the theoretical model. It includes high orderedsensitivity analySis, parametric analySis based on approximate expansion POlynomial of Tay1Or's progression and iterational perturbatbo, as well as erro control with the conaideratbo to boh accuracy and analytic efficiency. Taking the box shaped cover plate as aconcrete calculational example, the effect and app1icationalpmepects of variationalized analytic technique used in rapid designof mechanical structures are being studied.
