Controlled structure is not synchronized with the vibration of AVS devices


Respectively,[link widoczny dla zalogowanych], the Kf mouth ear + l [] TrK'7'Y '(tz) tB reaction controller is not synchronized with the controlled structure vibration. and (, similar to the type (1O) is also included m one, O equation (Note that the size of m different from the previous period, and accordingly, with the valve open or closed state of the matrix is ​​not the same.) The differential equations to be solved in the following initial conditions 7AY (t) = 0,7 Y (f) A 7Y (£。), y (f2) = 1, Y (Island) Xiao ;(£)+[ said. (£+,( F)] A (I7 +) HI △ y (£。)( f) l a t (£),( f l ... (z), (f ≤ t O. 04, the higher the effect instead of sync, but as £ increases,[link widoczny dla zalogowanych], the two curves closer. This may be due to small damping device, the device following the weak vibration controlled structure,[link widoczny dla zalogowanych], the reaction vary greatly, resulting from internal forces when the valve is closed higher. Figure 6 shows the quality control unit and control effect relationship. The figure for the control ratio of the quality and the ratio of the quality of controlled structure. The figure is not always better than the control effect of simultaneous synchronous control effect, which may be due to the valve device is turned on from the role. When the mass ratio of 0.2, the difference between the control effect l5 or so. 4 Conclusion Figure 6 device and control the quality of the relationship between effects of the above simulation results show that; (1) When the stiffness of control device is small, the assumption S device and synchronous vibration controlled structure may underestimate the effect of actual control device; (2) stiffness of the contrary,[link widoczny dla zalogowanych], when S is small, the damping device,[link widoczny dla zalogowanych], the control device and the controlled structure is assumed synchronous vibration control will overestimate the actual effect of the device; 2 Yan Weiming controlled structure and other devices are not synchronized with the vibration of S 255 (3) The quality of S appropriate device control is beneficial. In the S control, the fluid cylinder is not completely incompressible fluid, so the device should be between the true control effect with and without equipment is not synchronized with the vibration of the controlled structure between the income effect. Therefore, the preliminary conclusion that the S in the actual project implementation control, is basically controlled structure without considering the device are not synchronized with the vibration damping control is small, the device is not synchronized with the controlled movement of the structure of the effect is some influence, while the damping device is larger, this effect is relatively small, it has a larger device for damping control system S · D 0], the device is not synchronized with the controlled vibration of the structure can also be ignored.
