Research on evaluation method of impact resistance of side wall structure of ship superstructure

为解决常规建筑侧壁结构性能评估方法存在评估精确率较低的不足,提出了船舶上层建筑侧壁结构抗冲击性能评估方法研究。基于静载船舶侧壁结构极限承受能力的确定,对外界环境影响船舶侧壁结构受力进行计算分析,确定侧壁结构与冲量的关系,实现侧壁结构抗冲击性能的评估。试验数据表明,提出的抗冲击性能评估方法较常规评估方法,评估精确率提高47.75%,适合船舶上层建筑侧壁结构抗冲击性能评估。

In order to overcome the shortage of low accuracy in conventional evaluation methods of side-wall structure performance,a method for evaluating the impact resistance of side-wall structure of ship superstructure is proposed.Based on the determination of the ultimate bearing capacity of the side wall structure of a ship under static load,the force acting on the side wall structure of a ship under the influence of external environment is calculated and analyzed,and the relationship between the side wall structure and impulse is determined,so as to realize the evaluation of the impact resistance of the side wall structure.The test results show that the accuracy of the proposed method is 47.75%higher than that of the conventional method,and it is suitable for the evaluation of the impact resistance of the side wall structure of ship superstructure.
