Abstract: Under the action of shock wave due to non-contact underwater explosion, ships with small size or large stiffness will have the response of large rigid-body motion. Based on Taylor plate equation, and taking the additional mass of transverse motion into account, the kinematic equations of 2D cross-section under the shock wave action due to the non-contact underwater explosion were established. And the response of the rigid body motion of a ship to the explosion was calculated. The results are in good agreement with the experimental data, which shows that the present method can be applied in prediction of motion response of ships under shock wave action.

摘要： 在非接触水下爆炸冲击波载荷作用下，较小的船体或者刚度较大的船体会产生很大的刚体运动响应。以Taylor平板公式为基础，考虑横剖面运动的附加质量，建立二维横剖面在非接触水下爆炸冲击波作用下的运动方程。在此基础上，计算某艇在水下爆炸冲击波作用下的刚体响应，与实验结果比较一致，表明该方法可用于预报水下爆炸冲击波作用下船体的刚体响应。
