薄壁压力容器的有限元建模研究

Research on Modeling of Finite Element of Thin-walled Pressure Vessel

按照经典力学理论,对于薄壁压力容器的应力分析,大都采用近似数值计算方法,而运用有限元等数值模拟技术,能比较快速、精确地获得工作状态下的应力数值的大小,以此对结构的设计和优化等提供有力的理论支撑。

According to the theory of classical mechanics, for the stress analysis of the thin-walled pressure vessel, the approximate value calculation method is mostly adopted, but utilizing the numerical simulation technologies such as finite element method can obtain the stress values in working condition fast and precisely, providing the powerful theoretical support for structure design and optimization.
