Abstract

In this study, the nonlinear interactive characteristics between a track roller and a rubber crawler were investigated. The dynamic spring constants and the viscous damping coefficients of the rubber crawler were measured by using the dynamic viscoelastic measuring system with a varying range of frequency and preload. The results indicated that the relationships between the vertical load forces acting on the track rollers and the vertical displacements of the rubber crawler were approximately linear near the lug (core bar), whereas the relationships were nonlinear at the middle portion between the two lugs. The nonlinearity indicated by the hardening spring property could be represented by cubic nonlinearity. The dynamic interactive relationships between the dynamic spring force of the track roller and the displacement of the rubber crawler showed hardening nonlinearity near the middle portion between two lugs, while around the lugs were linear with a tendency similar to static interaction. And also, the higher the exciting frequency, the larger was the dynamic spring constant, while the viscous damping coefficient decreased. Furthermore, the dynamic model for agricultural rubber crawler vehicles based the non-linear interaction between the track roller and rubber crawler was developed, and comparisons of measurements and analytical simulations were performed in order to validate the analysis. The results indicated that the simulation based on the nonlinear interaction of the track roller and rubber crawler shows better agreement with experimental results than those of simulation, based on the conventional linear interaction.
