Abstract:

The structure of a comprehensive rockcutter interaction experiment platform is presented. An electrohydraulic servo control system is developed for the mentioned experiment platform. In this way, the stepless control of the thrust force and the advance speed of the disc cutters are achieved. The electrohydraulic servo control system developed meets the requirement of study on the relationship between the rock breaking parameters and the rock breaking efficiency.

Key words: rockcutter interaction, thrust system, electrohydraulic servo control system, experiment platform
