| 目的 基于核级管道支架的力学分析，针对性地提出非标支架优化设计方案。方法 核电站中管道支架为确保管道系统的安全运行发挥着至关重要的作用。针对工况复杂、要求严苛、承载恶劣的管道支架，为满足其支撑与抗震功能，通常采用非标设计。深入研究非标支架的力学计算和评定方法。通过有限元计算评定结果，发现支架设计中不满足规范要求项，提出非标支架优化设计方案。结果 首先针对支架整体结构刚度和稳定性不足，采取增加斜支撑与增强约束等结构性修改措施，进而确定增强支撑钢梁强度的优化方案，解决应力超过规范许用限值问题，最后对于问题集中的管道连接区域，提出局部支撑构件重新设计方案。结论 该优化方案可为核级管道非标支架设计提供借鉴和指导，以满足核电标准规范和设计要求。 |

| Objective To propose optimized design ideas and solutions of support based on mechanical analysis of pipe support. Methods Pipe supports play a crucial role in ensuring the safe operation of the pipeline system. In order to meet its supporting and anti-seismic functions, non-standard designs are usually adopted for nuclear pipeline supports with complex working conditions and strict requirements. In this paper, the mechanical calculation and evaluation methods of non-standard supports for nuclear pipes were studied in depth, to find out the items that didn’t meet the requirements on specification for pipe design and propose a non-standard stent optimization design scheme based on the evaluation results of finite element calculations. Results First of all, for the lack of the overall structural rigidity and stability of the supports, structural modification measures, such as increasing the oblique support and strengthening constraints were taken; furthermore, the optimization plan for strengthening the strength of the supporting steel beam was determined to solve the problem that the stress exceeded the specification allowable limit value; finally, for the pipeline connection area where the problems were concentrated, the redesign scheme of the local support component was proposed. Conclusion The optimization scheme proposed in this paper can provide reference and guidance for the design of non-standard pipeline supports, and meet the nuclear power standard specifications and design requirements. |
