Abstract
Estimation method based on multibody system modeling for Frequency Response Function (FRF) of a driving unit in a printer was developed. The multibody system consists of combination of many masses, fundamental springs and dumpers. Using multibody system modeling with fundamental elements, there are mainly two benefits for estimating FRF. One is that calculation is easy and the other is that modeling is easy especially input/output interface of the model. To verify the developed method, a trial estimation of FRF of an intermediate transfer belt unit in a printer was conducted. For modeling the unit, belt rollers were replaced with mass elements and the belt was replaced with spring element respectively. The trial indicate that the estimated FRF was closely match with experimental result.
