Model Order Selection of Autoregressive Process Based on the Reversible Jump MCMC and Its Application on Gyro s Drift Prediction;

On base of the order analysis theory,it takes transform of signal in time domain and then abstract the signal into different shafts.

This paper discusses the problems such as how to determine the model parameters and model rank when AR model is used to establish deformation forecasting model.

The paper analyzes the disadvantage of utilizing Fourier analysis to study the rotary machinery vibration signal,compares it with order analysis and represents the superiority,utilizes the virtual instrument LabVIEW to analyze the rotary machinery vibration signal and certifies it through example.

In this paper, a cut-and-try way is braught forward to diagnosetransmission faults on transmission performance test-bed with thesetheories: order analysis and expert system.

At the high speed, the key parts of milling machine appeared the vibration abnormal phenomenal, order analysis was done to the transmission system of the machine for this problem, proposed the work speed that the force vibration was corresponding to the first natural frequency, should be avoided when the machine works.

This method is based on the order tracking technique,angle domain average,amplitude and phase demodulation technique.

The order tracking technique, angle domain average technique and continuous wavelet transform (CWT) are introduced and applied specifically to gearbox fault diagnosis during run-up.

The outcome shows that using order tracking technology can effectively avoid the "frequency s.

The shortcoming of primary step measuring traditional oriented and the features of multivariate system,an identification method on multivariate system step response of multistep measuring based on Least Squares are given out.
