| Abstract: |
| The structure force in the braiding process of the braided hose skeleton layer was analyzed，and the calculation formulas of the braiding pitch and braiding tension of the hose skeleton layer were derived，so as to determine the important parameters of the braiding process of the hose skeleton layer.The results showed that，under certain braiding angle，keeping the braiding pitch constant could keep the radial and axial expansion of the hose in balance and keep the structure stable.The braiding tension had the periodic fluctuation characteristics.When the spindle ran near the outer ring of the track，the braiding tension was the maximum，and when the spindle ran near the inner ring of the track，the braiding tension was the minimum.The spindle rotary setting out generally occurred near the outer ring of the track，and the braiding tension troughs after setting out were slightly lower than other troughs. |
