| Abstract: | The lateral low-frequency oscillation of a tested plane has distinctive influence on the output of inertia lateral vibration transducers.In the process of testing,the influence of such kind must be well understood and corresponding measures must be taken in the data processing on the basis of all-round analysis of the response signal characteristics.By way of parenthesis,the specialty and complicity of processing of the lateral amplitude signals are also discussed and relevant advices are put forward. |
