Abstract

In order to study the synchronous performance of dualcylinder in the lifting system of segment erector, a 3D model of 900 mm segment assembly test platform is established. The hydraulic lifting system is designed, and the mathematical model of the system is established. The mechanicalhydraulic cosimulation model of the lifting system is established by means of AMESim and Adams software, and simulation analysis and test are carried out on the synchronous performance of dualcylinder. The results show that: (1) The displacement difference of dualcylinder ranges from 0.017 mm to 5.300 mm; (2) The load on the dualcylinder is the main factor affecting the synchronous performance of the dualcylinder; (3) The dualcylinder synchronous performance in the lifting system meets the assembly requirements of the segment. The experimental results are consistent with those of the cosimulation, which verifies the correctness of the simulation model.

Key words： segment erector; lifting system; mechanicalhydraulic cosimulation; synchronous performance
