摘　　要：某港的B1Z装船机使用年限较长,钢结构长期受到冲击载荷作用,尤其是臂架钢结构存在桁架结构交叉点位置锈蚀情况比较严重;同时因长期处于海岸环境,受到海水环境作用也会对钢结构造成较大影响,钢结构有效厚度减少。为了防止装船机臂架部位可能出现的疲劳屈服变形,文中采用SolidWorks软件进行了臂架框梁建模,利用Simulation有限元模块对臂架框梁的疲劳屈服变形进行了仿真分析,并参考分析结果对装船机臂架框梁容易出现疲劳屈服的部位进行了相应的加固。经过重载过程中对修复部分的应力测试,减少了应力集中,理论和实际相结合,使修复达到了理想的效果。The B1Z loader at the port has been in service for an extended period,during which its steel structure has been continuously subjected to impact loads,particularly serious rust and corrosion at the junctions of the boom’s truss structure.Additionally,the prolonged exposure to the coastal seawater environment has had a significant influence on the steel structure,leading to a reduction in its effective thickness.To prevent potential fatigue-induced deformation of ship loaders’boom,the boom frame beam has been modeled using SolidWorks software.Subsequently,the fatigue yield deformation of the boom frame beam was simulated and analyzed with the Simulation finite element module.Based on analysis results,susceptible areas of the boom frame beam on the ship loader were reinforced.Stress testing of the repaired section under heavy loads demonstrated a reduction in concentrated stress,confirming that the desired repair effect can be achieved by effectively integrating theoretical knowledge with application.
