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.%针对船舶碰撞事故鉴定问题，提出了事故数值模拟与评估通用流程，即船舶碰撞过程与损伤的数值模拟，船舶碰撞导致的船体振动的数值模拟，船舶碰撞导致的噪声数值模拟以及依据国际标准与行业标准综合评估。通过某一起的船舶碰撞事故真实案例，采用结构动力学有限元数值仿真技术以及声学数值仿真技术，对碰撞导致的损伤、船体振动以及产生的声响进行了数值仿真计算。
