笔者在模拟环境激励时加入了不同标准的噪声,从小波函数的选取、最大分解尺度及阈值的选取等方面进行对比分析,从信噪比和均方根误差两个指标来评价降噪的效果,提出适用于环境激励的结构动力响应降噪流程.

The paper added different standard noise when imitating the stimulation of environment,analyzed the choice of wavelet function,the biggest decomposing scale and the choice of threshold value,using two index,that is the ratio of signal and noise and the roof mean square error to judge the affection of noise reduction.Finally,put forward the technological process for reducing the noise.
