Simulation of Remote Control of Excavator Bucket Rod Hydraulic System Based on AMESim

With the vigorous promotion of artificial intelligence and the advancement of robotics, construction machinery has also continued to evolve in the direction of digitalization and intelligence. Hydraulic excavators have an important role in engineering construction, however, excavator operators encounter problems such as landslides and bad weather, which bring great challenges to drivers and industrial production, so remote control and unmanned driving of excavators gradually become the focus of research. For the realization of remote control of hydraulic excavator, this paper applies electro-hydraulic proportional control technology to the hydraulic system of a model of excavator, and designs the operating lever control system as an electro-hydraulic proportional control hydraulic system to realize the control of electrical signals without changing the original function of excavator. Simulation was performed by AMESim to create a solenoid proportional reversing valve model according to the selected model, and the flow control characteristics of the system were analyzed to determine the hydraulic system stability.
