Simulation Study on Hydraulic Assisted Steering System of Snake Mobile Conveyor

摘要

Snake mobile conveyor is a special structure new conveyor, its body composed of a number of independent frames which relative rotation and achieved conveyor's horizontal turning. In order to insure smoothness and controllability of turning, system executed predict the feedback control on the steering fuel tank using a hydraulic-assisted steering system. Control programs: the establishment of the virtual prototype of the machine - record tractor turning angle - calculation orbit of tractor frame - to calculate the steering cylinder corresponding stretched time and displacement - the controller to control assisted steering - Complete trajectory, and simulation analysis proved that this control method is feasible.
