Professor Bing Xu


Heavy duty hydraulic manipulator is widely used in concrete machinery, Aerial work truck, rescue vehicles and other Non-Road mobile machines. Due to the characteristics of high reachable operation space, some of its mobile machine arms weigh tens of tons and reach tens of meters in length. Its operation control is difficult and its safety is poor. Following the Mandatory requirements of machine safety laws and regulations, the design of heavy-duty hydraulic manipulator is based on the framework of functional safety standards, and the research work of hydraulic transmission system configuration optimization, information perception and control for mechanism kinemics and system dynamics, system safety risk assessment and so on is carried out. Moreover, facing on the era of intelligent construction, the high inertia heavy-duty manipulator is developing towards the fine control of multi degree of freedom and higher stability, which brings great challenges to the hydraulic transmission control technology. This report mainly introduces the hydraulic circuits configuration optimization, stability control principle and method of large heavy-duty hydraulic manipulator with typical equipment, as well as the risk assessment and safety management, etc.
