Arrangement for generating natural resonant oscillations of a mechanical oscillating system

摘要: An arrangement for generating natural resonant oscillations of a mechanical oscillating system includes an electromechanical oscillation exciter which on excitation by electrical signal generates drive force setting the in oscillations, sensor is formed as displacement and senses converts them to signal, circuit receives supplies with frequency signal. The phase control controls position dependence upon A shift produces 90° between so that condition at fulfilled. This makes it possible maintain very great accuracy high stability time even systems quality.
