Abstract: This paper seeks to develop and design a special automatic spreader equipment for railway car bogie, including the positioning and analysis device before hoisting, the locking mechanism and automatic release device during hoisting, and establishes a suitable new type of automatic spreader for the production, transfer and storage of railway car bogies. Based on ANSYS finite element analysis software, the static strength and stiffness of the model are analyzed to test the structural strength of the spreader system. Combined with the investigation, when the vertical and horizontal direction of the rated lifting capacity in the horizontal plane deviates from the center line of the spreader by 10% and 20% under the limit working condition, the kinematics and dynamics simulation of the special spreader structure are studied. Verify the motion characteristics of the spreader in the whole working process under different working conditions, which can provide reference for the design of large-scale similar products. Finally, it shows that under the action of 15t load, considering the dynamic load coefficient of 1.15 times, when the load center of gravity deviates from the center line of the spreader in the horizontal plane by less than 20%, the stiffness and strength of the spreader structure meet the use requirements. Its theoretical development size meets the planning requirements and provides calculation support for its structural lightweight.
