摘要： 分析船舶结构碰撞破损、能量转换和碰撞力间的关系，提出以临界撞速为耐撞性指标的船舶结构耐撞性评价模型，建立了船舶结构耐撞性优化方程.以2艘渔船发生正碰为例，开展了船舶碰撞的数值计算.比较了撞击速度对结构碰撞特性的影响，确定了临界撞击速度，给出了以提高船舶结构临界撞速为目标的结构改进建议.数值计算结果表明，基于临界撞速的船舶结构耐撞性评价指标具有可行性.

Abstract: By analyzing the relationship among structural collision damage, collision energy transformation and collision force of ship structure, the critical collision velocity was defined as an crashworthiness index, and the crashworthiness optimization formulation was established. The fishing vessels-vessels collision was taken as an example, numerical calculation of ship right collision was carried out. The influences of striking velocity on the collision characteristic such as deformation, energy transformation and collision force of the broadside structure of the struck ship were compared, the critical velocity of struck ship structure was determined, aiming at improving the critical collision speed of struck ship structure a proposal was given. The results of numerical calculation show that it is feasible to evaluate the crashworthiness index based on the safety critical velocity.

Key words: critical velocity, fishing vessels, crashworthiness, crashworthiness index
