Flexible Transfer System Based On High-speed EMU Bogie Bearing Research

In the multiple unit train, a new generation of the high-speed MU trains are latestachievement of china independent innovation for high-speed railway and its speed hasdirect relationship with the performance quality of the bearings which were in axiscabinets. The transport process of bogie bearing which belongs to a company’shigh-speed MU trains depend on manual handing, which has labor-intensive, low workefficiency and prone to dangerous accident sand other problems. To solve these aboveproblems, this thesis designed bogie bearings flexible transfer system which based onthe high-speed MU trains.The structure of the flexible transfer system is designed of modular by unit. Firstly,the traction load moving module of flexible transfer system, pose adjust module,holding claw module are designed. The structure of flexible transfer system of eachmodule are designed specifically, which include steering of the body frame design andtraction module carrier shift design, infrared control lifting device and cantilever beamof pose adjust module design, the lock claw of clamping jaws design.The motion analysis and simulation of flexible transfer system are completed.Using Cartesian coordinates and coordinate transformation to establish kinematicsmodel of pose adjustment module for flexible transfer system and solve and verificationthe pose adjustment module with the positive and inverse kinematics respectively.Meanwhile, use ADAMS virtual prototype software to kinematics simulation andverification for pose adjustment module. Through the analysis of simulation results, it isconcluded that workers registration form adjustment module applied force size.Flexible transfer system is mainly assumed strength check of parts by usingABAQUS finite element analysis software. Firstiy, get cantilever beam posture inadjustment module and stress-strain diagram of base uping under various conditions, atthe same time, analyze the cause of the stress and the elastic deformation in all kinds ofconditions. Secondly, verify the motion stability and the operation stability of theflexible transfer system.Electrical control system design of each module in flexible transfer system. Slect DC servo motor of traction load module and controller of DC servo motor. Completecontrol design of infrared lifting device in posture adjustment module and the control ofelectrical components. Chose telescopic cylinder of clip card claw module. Design andselect battery capacity of flexible transfer system. At the same time, complete the designof control circuit of the electrical components, to achieve electric control system offlexible transfer system in coordination state.
