Recently, tracked vehicles are being equipped with a rubber crawler and they are used for leisure vehicles, snow machines, etc. With these applications, the resonance problems are common knowledge. The vibration characteristics of crawlers are experimentally examined. They have some resonance points caused by the differences in thickness of the crawler. These vibrations will make some noise and possibly cause system destruction. In order to analyze these vibrations, an approximate analytical model, which is based on the linear wave equation, including an effect of crawler velocity is introduced. Vibration characteristics are compared with exact solution and the experimental result. In order to suppress the resonance vibration, a bang-bang control method, which is part of the variable structure system control, is adopted. The authors experimentally and theoretically examined vibration and control of the crawler. As a result, that control method provides the possibility of vibration suppression for the actual tracked vehicles.
