Study on Trispectrum Characteristics of MR Damper in Vibration Processes
In order to find out a new type of MR damper for block making machine, the signals of displacement in the vibration process during the test are collected and the time series AR model of trispectrum for analyzing the dynamic characteristics of the MR damper is built. It turns out that , in different working conditions, slices of trispectrum are applied to obtain the signal’s non-Gaussian, nonlinear amplitude-frequency characteristics which are very important for us to select the optimum working parameters of the MR damper.
