| Laminated board fault diagnosis method
5-order energy contribution of the former than the previous rate of 5-order frequency cell damage than the figure d 5 123 {5MODE energy contribution of the former than the 123 {5MODE soil before the 5-order rate of change rate of injury than in Figure 5 Vibration Engineering Unit No. 5 sauce Finally, draw the frequency table l Zhonggu the rate of change and shaded in Figure 1 in energy under each mode contribution ratio (Figure 6). Can be seen from the histogram,Abercrombie Deutschland, the frequency rate of change of unit ratio and energy under each mode is basically the same ratio of contributions. [Conclusion] This established a composite laminated plate injury diagnosis of new methods of energy, this method only in the calculation of non-destructive plate under each mode of energy distribution, combined with injuries before and after the change-order natural frequency can be more convenient and accurately diagnose the location and extent of a small injury and a large number of experimental data,abercrombie uk, calculations show that this method is feasible and effective. 2345MODE energy contribution rate than the reference ratio of change in 2345MODE ● 6 laps I shaded circle Injuries [1] whne, C.
