摘要

Characteristic values of the rubber crawler system for farm machinery, which are expressed as Fourier series, were identified by using the Gauss - Newton Method. And validity of the identified parameter was discussed through the simulation usingexperimental data. As the result, in the Fourier series of dynamic parameter of spring constant k and viscous damping coefficient c, excellent parameter convergence and simulation were observed by using the Fourier series's zero and first term of thedynamic model. Furthermore, it was clarified that the identification for model parameter which are fitted to the actual motion wave of the crawler system was possible by using the time series data observed in vertical and pitching direction of the crawler system.
