Test and analysis of vibration reduction effect of indoor test system based on reactor vibration reduction and isolation device

In order to evaluate the indoor vibration isolation performance of the reactor’s vibration isolation reduction device, we have introduced a novel indoor simulation testing system. This system assesses the effectiveness of vibration isolation by analyzing the acceleration response and spectral curves at corresponding points on the upper and lower levels of the vibration isolation platform. Additionally, we have introduced a new parameter to quantify the damping effect within the enclosure. The new indoor simulation testing system consists of an electromagnetic shaker, a vibration isolation system, and a foundation platform. It simulates the actual operating conditions of the reactor by generating time-domain signals of vibration acceleration, which are collected from field tests and reproduced via the reactor’s electromagnetic shaker. The study results indicate that the reactor’s vibration-damping device significantly attenuates the transmission of vibrations to the surrounding environment. The new simulation testing system demonstrates excellent replication capabilities, aligning test data with field data. Furthermore, the evaluation of the reactor’s vibration-damping effect through the reduction in vibration levels is efficient, offering valuable insights to engineering designers for predicting the damping performance of the vibration isolation device and planning field tests.
