基于传递路径分析方法的反应堆管道系统振动传递研究

Vibration Transmission Analysis of Pipe System for Nuclear Reactor System Based on Transmission Path Analysis Method

噪声源的识别、量化和传播途径识别是开展振动和噪声控制工作的前提。为满足工程实际中振动传递路径定量分析的要求,将传递路径分析(TPA)应用于反应堆管道系统的振动传递特性研究中,通过测量各振动传递路径的频率响应函数、各激励点和目标点的响应以及激励力估算,进行传递路径分析,进而得到设备与管路对于目标点振动的贡献量。通过用某典型反应堆管道系统模型试验,验证了该方法的准确性和有效性。

The noise source identification, qualification and recognition of transmission path are the precondition of the vibration and noise control. In order to meet the engineering requirement of quantitative vibration contribution analysis, the transmission path analysis method was applied to the vibration transmission analysis of the pipe system for nuclear reactor system. By measuring the frequency response function(FRF) of each vibration transmission path, the vibration velocity of exciting points and evaluation points, and estimating the exciting forces, the TPA was performed and the vibration contribution of the facilities and pipes to the evaluation points were obtained. The experiment on a typical pipe system was used to verify the accuracy of proposed method.
