Co-simulation Of Mechanical And Hydraulic Systens For Segment Erector

In recent years, many researches on segment erector were carried on, most of themhave adopted the single approach. Some only do analysis of kinematics and dynamics ofworking device with dynamic simulation software, while ignoring the hydraulic systemto provide the driving force; Some only do analysis of hydraulic system with hydraulicsimulation software, while ignoring the real situation of the device in the course of work.The real situation in the course of work can not been accurately analyzed by aboveunilateral analytical methods. The paper is found a co-simulation method to combinedynamic simulation software ADAMS and hydraulic simulation software AMESim intoone condition. Through this method, segment erector of the hydraulic system and theworking device as a whole would be analyzed, and come out the real characteristics ofworking process.In the paper, lifting and rotating conditions of segment erector are investigated bytwo kinds of software interface module, and then the flow, speed, displacement andother parameters of the dynamic characteristics can been obtained.During co-simulation being carried on, the original hydraulic system is improved.Through adding balancing module into the rotary circuit to effectively solve theproblem of beyond motor load caused by low speed and heavy load. Using theparallelogram lifting mechanism, synchronous movement is realized and an importantbasis is provided.In this paper, the main accomplished works as follows:(1) The paper first summarizes the research status and development trends of thesegment erector.(2)The second part establishes the dynamics model of segment erector. The generalprocess includes: drawing the three-dimensional model of segment erector with3Dmodeling software Pro/E, importing the model into the dynamics simulation softwareand creating a dynamic model of the segment erector in ADAMS.(3) The third part builds of hydraulic system of the segment erector. The process is:based on the principle of the hydraulic system to establish the simulation model ofAMESim, and build the interface of two simulation software for next s co-simulation.(4) The forth part carries through the co-simulation of segment erector mechanical and hydraulic systems, and analysis simulation results.(5)The research results have been summarized, and made a future work prospects.
