英文摘要：

A general numerical simulation and evaluation procedure for the accident of ship collision is proposed. By applying structural dynamic finite element numerical simulation technology and acoustic numerical simulation technology, detailed models for accident analysis of ship collision are presented. Collision process, structure damages, vibration of ship structure and noise resulting from collision are calculated. Crews’ perceptions of impact noise in cabins are discussed with relevant maritime codes and regulations.
