摘　　要：本文是在研究滚装船横摇运动的基础上，考虑进水与气流相耦合，利用修正的Bemouli方程建立破舱模型的。本文研究两种进水情况：其一，破舱内的突然定量进水，此后时间内舱内与舱外再无水流交换；其二，破船内持续进水。研究的重点是舱内水及舱内气流的耦合对横摇运动的影响。A dynamic model is presented of the roll motion of damaged RoRo vessels which couples the internal cross-flooding flow and the air action in the equalizing compartment. The cross-flooding flow and the air motion are modeled by a modified Bernouli equation. Two limiting flooding cases are examined: The sudden ingress of a certain amount of water to the damaged compartment with no further water exchange between the sea and the flooding compartment; the continuous ingress of water to the damaged compartment.
