Abstract: In this paper, a study of
torsional undamped free vibration problem on the basis of
experiments is presented. The two degree of freedom vibration
model of harmonic gear drive using for general purpose is
established and mathematical solution of its characteristic
value is presented. Based on calculation of the XBD80-100-120-Ⅰ
harmonic gear reducer, the sensitive parameters and sensitive
interval effecting on first order natural frequency can be
obtained. The experimental result proves that harmonic gear
drive always runs in the performance of interference of
multifrequency exciting force. By means of 3-dimension frequency
spectrum figure of the tangential acceleration of output shaft
in relation to different rotating frequency of motor, the first
order natural frequency of the system can be determined.
