摘　　要：基于有限元软件ADINA,分别建立梭式止回阀与旋启式止回阀的流固耦合有限元模型,通过调用FSI模块,实现两者的流固耦合仿真分析。通过对比分析数值模拟结果发现:与旋启式止回阀相比,梭式止回阀的启闭特性好、流场对称性好,有利于降低噪声与振动。Based on the finite element software ADINA, fluid-structure interaction models of the shuttle back pressure valve and the swing check valve were established respectively. Their fluid-structure interaction simulation analyses were accomplished by calling FSI module. Through analyzing numerical simulation results, it is known that comparing to the swing check valve, the shuttle back pressure valve has better on-off characteristic and its flow field has better symmetry, which is helpful to reduce noise and vibration.
