Abstract: Aiming at some probolem of the high speed tain carrige preassembly,such as nonreusable, poor flexibility and low degree of automation, the high speed railway carriage flexible preassembly was studied. The preassembly composed of the internal and external walking gantry and corresponding manipulator was proposed. The power of the internal gantry manipulator positional movement and positioning of the assembly points was provided by the external walking gantry manipulator. The flexible assembly control system combined with PLC control software and humanmachine interface software was achieved through development of distribute control system based on delta touch screen and PLC. The preassembly process automation and intelligence was achived finally through the PC software planning and management. The experimental results show that the system can realize the real simulation of the railway carriage assembly environment, and accurately locate the position of the key components inside the carriage, further more it can flexibly configure according to carriage conditions to achieve a number of functions such as flexible assembly .This system has some practicability and promotion value.
