The inversion method was used to test vibroacoustic processes in large-size machines used in opencast mines of rock material. When this method is used, the tested machine is replaced with a set of substitute sources, whose acoustic parameters are determined on the basis of sound pressure levels and phase shift angles of acoustic signals, measured with an array of 24 microphones. This article presents test results of a combine unit comprising a crusher and a vibrating sieve, for which an acoustic model of 7 substitute sources was developed with the inversion method.
倒置法被用于测试露天矿用大型机器的声振过程。使用该方法时，将被测机器替换为一组替代源，其声学参数是根据声压级和 24 个传声器阵列测量的声信号的相移角确定的。本文介绍了一种由破碎机和振动筛组成的联合机组的测试结果，该机组采用倒置法开发了 7 个替代源的声学模型。
