【摘要】 利用整体胀形法制造球形容器是一种新的造球技术。本文应用非线性有限元程序对32面足球式不锈钢壳体的液压胀球过程进行了数值模拟,分析了壳体的位移变化过程,并与实验结果进行了对比。结果证明,有限元方法较好地模拟了壳体的液压胀球过程,与实验结果吻合较好。更多还原

【Abstract】 The integrally hydrobulging process of spherical vessels is a new technology for manufacturing spherical vessels. In the present paper non-linear finite element method is used to simulate the hydrobulging process of a stainless polyhedral shell with a soccer stucture, and the variational process of the shell displacements is analysed, and also is compared with the experimental results. It’s proved that the FEM program simulates the hydrobulging process of the shell very well, and the FEM results are in good agreement with the experiments.更多还原
