Abstract: Through the study of the present fiber winding machine and the analysis of its working principle and structural characteristics, many problems such as discontinuity and low efficiency in the fiber production process are found in the current operating system. Then the fiber winding machine is improved with a better work-flow. The molding structure of the multi-station fiber winding machine is designed, and its 3D model which is introduced into Workbench to perform a simulation analysis is constructed with Solidworks. This paper optimizes the original fiber winding machine with technical measures including Gantry layout structure, loading-and-unloading mechanism of mandrels with manipulators, power-split output device of the head-stock and an alternative working mode with two mandrels. Therefore, the integrity of the structure is guaranteed. The labor cost can be saved and the automation level of the fiber winding machine is improved, allowing the winding car to realize continuous winding production at the maximum level with the help of the manipulator and consequently significantly enhanced productivity. At the same time, the response surface optimization of the beam is adopted to reduce the weight of the beam and save the cost. On this basis,the beam of fiber winding machine is statistically analyzed to determine whether the design is reasonable.
