摘要

摘要: 为了解决水射流蓄能器筒体因承受高压而屈服失效的问题,采用了预应力复合结构设计,并运用等强度理论,确定了蓄能器复合筒体的内筒、外筒半径,分层半径及最佳过盈量等相关参数。然后利用ANSYS对该筒体模型进行有限元分析,通过路径提取的方法,得到了仿真模型沿壁厚有效节点的等效应力值, 并得到了不同内压时的等效应力沿壁厚方向的分布曲线。由仿真结果可知,筒体设计参数满足预期强度要求。

Abstract: In order to solve the yielding failure problem of water jet energy accumulator barrel due to high pressure, the prestressed composite structure design and the theory of equal strength are used to determine the parameters of accumulator barrel, such as the internal cylinder of the composite cylinder, the radii of the inner and outer cylinders, the radius of sub-layer and the optimal interference. Then the ANSYS software is used to analyze the cylinder model with the finite element method, the equivalent stress of the effective node along the wall thickness of the simulation model is obtained by path extraction method and the distribution curves of the equivalent stress along the wall thickness with different internal pressure are also obtained. By analyzing the simulated results and curves, the design parameters of accumulator barrel meet the expected strength requirement.
