Autoregressive trispectrum and its slices analysis of magnetorheological damping device
A combined magnetorheological damper combined with rubber spring and magnetorheological damper is addressed. This type of damping device has inherited the merits of rubber spring and the magnetorheological damper. The test damping device is made up of combined magnetorheological damper, amplitude controller, signal collecting device, computer software for dynamic analysis, etc. When a zeromean and non-Gaussian white noise interfere with the device, a time series autoregressive(AR) model is conducted by using the sampled experimental data. Trispectrum and its slices analysis are emerging as a new powerful technique in signal processing, which is put forward for investigating the dynamic characteristics of the magnetorheological vibrant device. The present of trispectrum and its slices analysis change with the variation of controllable working magnetic field of the damper correspondingly. It is indicated that AR trispectrum and its slices analysis methods are feasible and effective for investigation of magnetorheological vibrant device.
