介绍了频域法的基本理论,模拟井下采煤工况对连采机进行了有限元分析,利用连采机井下测试数据及有限元分析输出、输入识别出连采机井下采煤受到的载荷,为了揭示连采机井下采煤时受到的随机载荷内在的统计规律,运用一维载荷谱的编制理论,编制了连采机载荷谱。 Introduced the basic theory of frequency domain method, simulated underground mining conditions on the continuous mining machine for the finite element analysis, the use of continuous mining test data and finite element analysis of the output input to identify the continuous mining underground mining load In order to reveal the inherent statistical rules of stochastic loading when underground coal mining, the one-dimensional load spectrum theory was used to compose the continuous mining load spectrum.
