The design and implementation of a two-dimension motion platform for track reappearance

This paper describes the design and implementation of a two-dimension motion platform equipment, which can meet the requirements to simulate the vibration of the real vehicle. According to the modeling and simulation of vehicle trajectories, the mechanical structure of the platform has been designed, and a motion controller has been developed based on DSP and ARM, with corresponding motion control, communication and other software systems. The two-dimension motion platform system, using G code to describe the real vehicle vibration, parses the G code onto the motion controller, which controls the motion platform equipped with the grating ruler for position feedback, to achieve full closed-loop precision control. The experimental results verified the effectiveness of the two-dimension motion platform. It lays a foundation for the test of laser positioning and tracking of autonomous mining equipments.
