For satisfying the requirements of composite material fiber winding, the fiber guide device of the fiber winding machine is carried out structure design and pressure analysis. Through design of longitudinal and horizontal motion structure, rotation equipment structure and branching structure, use Solidworks for 3D modeling. The designed parts of the fiber guide device were assembled, and the sizes of the parts were adjusted for winding function. Use simulation to carry out pressure analysis for pressed part 3D model. Use winding equipment for cylinder winding verification. The test result shows that the parts can meet the equipment operation requirement.
