摘要：An electro-hydraulic control system of high speed segment assembling was proposed in order to solve the current problem of low speed and big start-up impact in rotary system of segment erector.The system used an accumulator circuit with variable speed integration.The system could get higher kinematic accuracy and the system impact could be effectively restrained through the real-time adjustment on integral coefficient according to the amplitude of error signal.The concussive impact of starting could be further reduced by setting accumulators on both sides of the motor for absorbing hydraulic impact.A rotary system of segment erector was constructed and analyzed by AMESim software after verifying that the simulation data is equivalent to the test data.Results show that the speed of rotary system in segment erector can be improved from 1.5 r/min to 6 r/min by using the high speed and low impact control method.The system impact of start-up phrase can be effectively reduced and the system impact will not increase with the improvement of rotating speed.
