蒸汽管路系统用于输送舰船动力设备所需要的蒸汽，是舰船动力系统的重要装备。开展蒸汽管路抗冲击性能研究对保障舰船的正常运行，提高舰船的生命力与战斗力均具有重要的意义。本文选取一典型蒸汽管路段为研究对象，建立数值分析模型，分别对频域及时域冲击载荷作用下蒸汽管路抗冲击性能进行分析。基于计算结果，提出改进方案，并对改进后蒸汽管路抗冲击性能进行对比分析。在此基础上，进一步分析了阻尼系数对蒸汽管路抗冲击性能影响规律。研究表明，在弹簧吊架上增加阻尼元器件可有效改善蒸汽管路抗冲击性能。随着阻尼系数增加，蒸汽管路最大冲击应力呈现出先降低后升高的变化规律，表明阻尼系数的选取存在一最优值。
Steam pipeline System is used for conveying the steam power to marine power equipment, which is an important equipment in marine power system. Then, the research on the shock resistance performance of steam pipeline is significant to ensure the normal operation of ships and improve the vitality and combat capacity of ships. In this paper, a typical steam pipeline section was selected and the numerical model was established to analyze the shock resistance performance of steam pipeline under the impact load in frequency-domain and time-domain. Based on the results, the modified scheme was presents and the shock resistance performance of improved steam pipeline was compared. The influence of damping coefficient on shock resistance performance of steam pipeline was further analyzed. The results show that shock resistance performance of steam pipeline could be improved effectively by adding a damping elements. With the increase of damping coefficient, the maximum impact stress of steam pipeline shows the change rule of first decreasing and then rising. Therefore, the selection of damping coefficients has an optimal value.
