摘 要:在沿海地区与港口城市,为应对海洋火灾及其他突发事件,消防船上的吊机结构设计至关重要。对1000吨级消防船折臂吊机基座结构进行有限元分析,采用MSC Patran/Nastran 2019软件模拟8种不同工况下的应力状态,以验证基座结构是否符合中国船级社(China Classification Society,简称CCS)《钢质海船入级规范》(2021)。在原有设计基础上,将关键横梁的角钢尺寸(边长×厚度,单位为mm)从12×300及12×80调整为13×400及13×80,并在强横梁与肋骨连接处添加加强筋板与焊接通孔,将基座材料替换为抗腐蚀钢材AH26,并降低基座筒体高度值等。分析结果表明,优化后的基座结构在各工况下的应力降低了10%,满足规范要求,在不利条件下作业的稳定性和安全性得到提高,设备的耐用性和经济效益得以提升。研究结果为消防船起重设备的结构优化提供了理论支持。The structural design of cranes on fireboats is crucial to responding to marine fires and other emergencies in coastal areas and port cities.A finite element analysis was carried out on the base structure of knuckle boom cranes for 1000-ton fireboats.The stress state of the base under eight different working conditions was simulated with the software MSC Patran/Nastran 2019 to verify that the base structure is in compliance with the Rules and Regulations for the Construction and Classification of Sea-going Steel Ships 2021 by China Classification Society(CCS).Based on the original design,the angle iron size(side length×thickness,in mm)of the major beam was adjusted from 12×300 and 12×80 to 13×400 and 13×80 accordingly.Reinforcement plates and welding through-holes were added at the joints between the web beams and the ribs.The original material of the base was replaced with corrosion-resistant steel AH26,and the base cylinder height was reduced.The analysis results show that the optimized base structure has reduced the stress by 10%under all working conditions,meeting the requirements,and that its stability and safety under unfavourable operation conditions are enhanced,improving the durability and economic efficiency of the equipment.The results provide theoretical support for the structural optimization of crane equipment on fireboats.
