| Abstract: |
| 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. |
