Способ измерения параметров свободно затухающих колебаний крутильного маятника (частоты и коэффициента затухания), включающий возбуждение колебаний маятника до амплитуды 4-7 угловых градусов, регистрацию с помощью лазера и многоэлементного фотоприемника временной зависимости угла отклонения маятника от положения равновесия при свободных затухающих колебаниях, отличающийся тем, что полученную кривую разбивают на несколько (5-10) участков, аппроксимируют каждый из участков экспоненциально затухающей синусоидой, строят амплитудные зависимости коэффициента затухания и частоты, затем аппроксимируют эти зависимости полиномиальными функциями и рассчитывают значения коэффициента затухания и частоты колебаний при нулевой амплитуде путем экстраполяции полученных амплитудных зависимостей.A method for measuring the parameters of freely damped oscillations of a torsion pendulum (frequency and attenuation coefficient), including excitation of oscillations of the pendulum up to an amplitude of 4-7 angular degrees, registration with a laser and multi-element photodetector of the time dependence of the angle of deviation of the pendulum from the equilibrium position with free damped oscillations, characterized in that the resulting curve is divided into several (5-10) sections, each section is approximated by an exponentially damped sinusoid, and amplitude curves are built the attenuation coefficient and the frequency, then approximate these dependencies by polynomial functions and calculate the values of the attenuation coefficient and the oscillation frequency at zero amplitude by extrapolating the obtained amplitude dependences.
