Изобретение относитс к радио- электронике и может быть использовано при изготовлении измерительных приборов.The invention relates to radio electronics and can be used in the manufacture of measuring devices.
По основному авт. св. № 568149 известен способ регулировани резонансной частоты механической колебательной системы путем изменени ее эквивалентной массы, при этом к механической колебательной системе прикладывают силу, пропорциональную ускорению ее движени lAccording to the main author. St. No. 568149, a method is known for controlling the resonant frequency of a mechanical oscillatory system by changing its equivalent mass, and a force is applied to the mechanical oscillating system proportional to the acceleration of its motion.
Недостатком известного способа вл етс ограниченный диапазон регулировани резонансной частоты механической колебательной системы.The disadvantage of this method is the limited range of adjustment of the resonant frequency of the mechanical oscillatory system.
Цель изобретени - расширение пределов регулировани .The purpose of the invention is to expand the limits of regulation.
Данна цель достигаетс тем, что согласно способу к механической колебательной системе дополнительно прикладывают силу, пропорциональную перемещению , а модуль и направление действи обеих сил измен ют.This goal is achieved by the fact that according to the method, a force proportional to the displacement is additionally applied to the mechanical oscillatory system, and the modulus and direction of action of both forces are changed.
