| Abstract: | In this report, the dynamic behaviour of a tractor-vibrating subsoiler system was analysed theoretically and experimentally. From a simulation using a mathematical model of this system and some field experiments, it was determined that the Virtual Hitch Point (VHP) is the parameter that most affects the vibrations of a tractor's body. By setting the VHP at an optimal position, the acceleration of a tractor's body was reduced considerably. |
