Abstract
The idea of measuring gear transmission system(TE)with photoelectric encoder instead of circular grating is put forward.Stationary random of TE signal and validity of the experimental data of planetary gear train TE is verified.Power spectrum density parameter of TE signal is estimated with Burg algorithm in autoregressive(AR)model
and corresponding curve is drawn and message is analysed.The result proves that using photoelectric encoder to measure TE instead of circular grating is feasible and valid.
