METHOD FOR CALCULATION OF ASYNCHRONOUS MOTOR VIBRATIONAL POWER

摘要

A method for calculation of asynchronous motor vibrational power involves measurement of one vibroparameter. The harmonic composition of vibrational acceleration signal is used for calculation, the calculation of vibration velocity harmonics is carried out by harmonics of vibrational acceleration. Algorithm based on discrete sequence convolution theorem is used for calculation of instantaneous vibrational power on the basis of orthogonal harmonic components of vibrational acceleration and vibration velocity.
