The Study on the Vibratory Soil Cutting of Vibrating Subsoiler (Part 4)

Dynamic Behaviour of Tractor-Vibrating Subsoiler System and the Effect of Virtual Hitch Point

Abstract

In this report, the dynamic behaviour of a tractor-vibrating subsoiler system was analyzed theoretically and experimentally. From a simulation using a mathematical model of this system and some field experiments, it was clarified that the Virtual Hitch Point (VHP) is the most effective parameter on the tractor body. vibration. By setting VHP on an optimal position, vibration of tractor body was reduced considerably. And it was also clarified that the cutting directional angle β is the one of effective parameters on tractor body vibration.
