摘　　要：针对长输油气管道中橇装设备(过滤橇)底座应力极限问题,采用模拟方法对底座受力(轴向力、弯矩、扭矩、剪力以及位移)情况进行分析。结果表明,最大轴向力、弯矩以及扭矩均出现在过滤器所在位置,而最大剪力出现在吊耳位置;吊耳处橇座主梁的位移量为正值,而在吊耳之外的橇座主梁的位移量为负值。通过计算发现,过滤橇吊装过程中最大应力为58.2 MPa,最大位移为8.74 mm,均满足设计要求。证明该橇座方案的合理性以及吊耳布置的合理性,该方案的设计可为橇装设备的橇座设计提供参考。For the issue of determination of stress limit in the base of skid-mounted equipment(filter skid),in this article,the simulation was used to analyze the loading condition for the base,including axial force,moment,torque,shear force and displacement.It was shown that the maximum axial force,moment and torque are all located at filter,while the maximum shear force is located at lifting lug;the displacement of main beam on skid seat at lifting lug is positive,but the displacement of main beam on skid seat away of lifting lug is negative.From the results of calculation it was found that the maximum stress was 58.2 MPa and the maximum displacement is 8.74 mm in hoisting process,and both were qualified.It has been proved that both the design of skid seat and the arrangement of lifting lug are appropriate,which may be referenced for design of other skid seat.
