Design and control of operating manipulator for excavator working device

摘要

In order to keep the operator safe when excavator is working in dangerous areas, an operating manipulator is designed for excavator working device. The manipulator is mainly made up of three parts: mechanical structure design, hydraulic circuit design and control system design. The 3d model of mechanical structure is built and analyzed. The model of the control system is built, the PID controller is designed and the control effect is tested by simulation analysis.
