Hydraulic simulation of the support legs of compact crane for substation based on AMESim

The compact crane plays a crucial role in equipment replacement and transportation operations within substations, necessitating the resolution of issues pertaining to supporting stability and operational reliability during its use. To address these concerns, a specific compact crane tailored for high-voltage substations is designed, incorporating specially engineered folding legs. Subsequently, theoretical analysis is conducted to ensure force and torque balance across all four legs, enabling calculation of the maximum supporting force under various working conditions. Finally, AMESim software is employed to simulate and analyze the hydraulic system governing the crane's legs while also designing a visual interface for parameter observation and optimization purposes. The results obtained from both theoretical analysis and simulation demonstrate that the proposed hydraulic leg system effectively supports crane operation while ensuring operational stability.
