Active vibration isolation system coupled double-controlled trial of
Control. It can be seen when the active control system, inhibit the work of the lower layer vibration isolation system, the quality of vertical vibration and lateral vibration of a roll coupling, thus effectively isolating the vibration of the top quality multi-directional coupler to the ground O. 7O. 6, O. 5 · O. 40.3O. 2O. 1O. Ojmz (a) 1 号 measuring point of Vibration Engineering Section 16 (b) 2 号 Diesel 1000r/min measured points in Figure 5 to control the transmission spectrum before and after. 4 Conclusion (1) In this paper, active vibration isolation of multi-adaptive thinking. It is based on the assumption that the lower quality is rigid and multi-error-IMS algorithm, a representative for the lower point on the quality of the vibration response control. That is lower in the double vibration isolation system, select the appropriate quality point of pick-up point as the error evaluation,[link widoczny dla zalogowanych], in all pick-up point of the effective suppression of vibration case,[link widoczny dla zalogowanych], the lower the quality of the natural vibration coupling has been effectively controlled, thus isolating the Coupled Vibration of Diesel Engine Multi-directional transmission to the ground. (2) multi-frequency signal of an actual diesel engine vibration signal as the input vibration source was simulated tests. The results showed that the lower quality in a variety of conditions at the two pick-up points have been effectively suppress vibration, 1 measuring point vibration damping capacity of 4 ~ 14dB, 2 号 measuring point vibration damping capacity of l1 ~ 13dB,[link widoczny dla zalogowanych], which effectively suppressed the direction of lower quality multi-coupled vibration, isolation of vibration transmission to the ground. Thus,[link widoczny dla zalogowanych], this multi-adaptive active vibration isolation strategy for multi-directional coupling vibration active control is feasible, simple, and practical. (3) In principle, the basis of changes in the actuators and pick-up point location, you can achieve more active control of coupled vibration direction. If the two actuators arranged on the diagonal in the lower quality, will be able to increase the original basis of the longitudinal coupled vibration of a pitch control. References 1 Yang Tiejun.
