Abstract

A method is developed to suppress the resonances of the transverse vibrations of the support plate of an active vibration protection device, which makes it possible to expand its active frequency range and reduce the transmission coefficient of vibrations. A second additional control loop is used to control the individual, selected resonances of the plate. Its inertial service thrusters and accelerometers are located on the plate (or in the volume of the plate) in certain positions near the maximum of the wave, and filters tuned to the resonance frequency are installed in the electrical circuits. To describe the structure, a structural diagram is used, consisting of electrical and mechanical impedances, which represent the resonances of the support plate mounted on elastic supports, the resonances of its transverse vibrations, and the resonances in the chain of inertial service thrusters. Application of the theory of electrical circuits makes it possible to determine the dynamic behavior of the control system, as well as the structural and power characteristics of its nodes.

防振装置支撑板横向振动共振的主动抑制

摘要

提出了一种抑制振动主动保护装置支撑板横向振动共振的方法，可以扩大其有效频率范围，降低振动传递系数。第二个附加控制回路用于控制板的个别选定共振。它的惯性服务推进器和加速度计位于波的最大值附近的某些位置的板上（或板的体积内），并且在电路中安装了调谐到谐振频率的滤波器。为了描述结构，使用了结构图，由电阻和机械阻抗组成，代表安装在弹性支架上的支撑板的共振，其横向振动的共振，以及惯性服务推进器链中的共振。应用电路理论可以确定控制系统的动态行为，以及其节点的结构和功率特性。
