| 目的 研究电缆桥架的受力规律。方法 采用通用有限元程序ANSYS对电缆桥架进行整体建模与力学分析，探讨S2型支架、S4型支架以及梯形支架的抗震能力，研究不同方钢长度和不同托臂层数对支架抗震能力的影响，并探讨三种截面形式的托臂承载能力。结果 梯形支架比其他两种支架抗震能力强。增加方钢长度和托臂层数会提高支架的受力，降低其抗震能力。双层异形钢截面的托臂更能有效地提高其承载能力。结论 为以后核电站电缆桥架的自主设计和改进打下了基础。 |

| Objective To research on the stress rules of the cable tray. Methods Overall modeling and mechanical analysis of cable tray were carried out with the ANSYS finite element method. The seismic capacity of the cable tray for S2, S4 and trapezoid was discussed. Influences of different length of square steel and different number of bracket arm on the seismic capacity were discussed. Furthermore, the carrying capacity for bracket arm of three different cross-sections were discussed. Results The seismic capacity of the trapezoid cable tray was stronger than other two kinds of trays. If the length of square steel and number of bracket arm were increased, the force of the cable tray would be raised and it’s seismic capacity would be reduced. Compared with the other two forms of the bracket arms the bracket arm of the profiled steel cross-section had more effect on the carrying capacity of the try. Conclusion It lays a foundation for the self-design and improvement of cable tray in nuclear power plant. |
