某大型装备液冷机组振动测试及减振优化

目的了解大型装备液冷机组振动情况;评估工作环境人员舒适性;采取合理措施,降低大型装备的液冷机组振动对装备可靠性及装备中工作人员的身体健康的影响。方法对某大型装备的液冷机组开展振动测试及舒适性评估工作,并依据振动分析结果对原有减振方案进行减振优化。结果对比原有减振方案和优化方案对应测点的振动响应,发现优化方案的振动响应明显减小,最大衰减5.55 dB。减振优化后,振动量值从0.555m/s~2下降到0.295m/s~2,根据国家标准GB/T13441.1-2007中的规定,人员在此环境工作时,不会感到不舒适,人员舒适性满足标准要求。结论工作环境人员舒适性满足相关标准要求,减振优化方案效果明显。装备服役后,使用情况良好,进一步证明了减振优化的有效性。

Vibration Test and Isolation Optimization of Large-scale Liquid Cooling System

The work aims to find out the vibration of the large-scale liquid cooling system, assess the comfort of personnel in working environment and reduce the influence of vibration of large-scale liquid cooling system on the equipment reliability and personnel health with reasonable measures. Vibration test and comfort assessment were carried out to some large-scale liquid cooling system and the original isolation scheme was optimized based on the vibration analysis results. By comparing the vibration of the corresponding points of the original isolation scheme and the optimized isolation scheme, it was found that the vibration of the optimized scheme significantly reduced and the maximum attenuation was 5.55 dB. After the optimization of isolation, the vibration value reduced from 0.555 m/s2 to 0.295 m/s2. According to the standard GB/T 13441.1-2007, personnel might not feel uncomfortable when working in this environment, so the comfort met the requirements of relevant standards. Personnel comfort meets the requirements of relevant standards and the isolation optimization is effective. The equipment is in good condition after delivery, which further proves the effectiveness of the isolation optimization.
