舰船设备冲击动力响应在不同边界条件下的比较

Transient Dynamic Response of Ship under the Shock with Different Boundary Conditions

针对舰船设备抗冲击的具体情况,建立了模型舰船及附链水的三维有限元模型。计算了考虑流固耦合作用,舰船在不同边界条件下受到冲击时的瞬态动力响应。计算表明,可以建立舰船的部分模型,通过合理地确定其边界条件,得出较为真实的仿真计算结果。

The 3D ship model is created with the FEA software ANSYS according to the shock from the ship itself.Part of the ship model can be done under reasonable boundary condition according to the numerical calculation result comparison under different boundary conditions.
