The Research on Time-varying Parameter Identification in Support Beam under Moving Mass
This paper reviews the current knowledge about timevarying parameter identification in support beam under moving mass. The basic models of support beam are described first. Then three classical methods of identification are introduced. Finally, Interpretive Method (IM) is applied to the cantilever and the inertia force which is between the beam and moving mass has been numerical calculated. According to comparison of numerical calculation with different parameters model by using Interpretive Method (IM), relative percentage error is defined. In calculation, only one parameter can be changed, i.e. changing sampling frequency, accuracy of natural frequency or the order of modal. According to the results of identification, the effect of different parameters on the result of identification is discussed and an optimal set of parameters is obtained.
