过度加速度是国际海事组织（IMO）讨论的完整稳定性的五种失稳模式之一。通过直接稳定性评估（DSA）的试算和模型试验，验证了两种直接稳定性评估预测短波峰不规则波中船舶运动的方法。频率响应线性叠加和时域模拟计算的船舶在短峰不规则波中的运动与模型试验结果吻合较好。利用实验验证的预测方法和北大西洋的波散射表，计算了两种预测方法的长期概率，结果越来越接近。用两种预测方法得到的长期失效概率评估的DSA是相同的。
The excessive acceleration is one of five stability failure modes for intact stability being discussed at IMO. The trial calculation for Direct Stability Assessment (DSA) and the model test have been carried out to verify two prediction methods of ship motions in the short-crested irregular waves for DSA. The ship motions in the short-crested irregular waves calculated by the linear superposition of frequency responses and the time domain simulation agree well with the results of the model test. Using experimentally validated prediction method and wave scatter table of North Atlantic, the long term probabilities have been calculated and the results obtained by two prediction methods become closer to each other. DSA evaluated by using the long-term failure probabilities obtained by two prediction methods are same.
