| 中文摘要: |
| 采用Abaqus非线性有限元分析软件对Φ19 mm钢丝缠绕液压胶管受内压过程进行模拟。通过改变内外层钢丝角度，得到一定长度的钢丝缠绕胶管受内压后管体形变及钢丝所受拉力和钢丝层应力分布情况。结果表明：钢丝角度排列一定且内压大于10 MPa时，管体形变和钢丝所受拉力随内压增大趋于线性增加；内两层钢丝角度固定时，管体形变及钢丝所受拉力随外两层钢丝角度增大而减小。 |
| 英文摘要: |
| The finite element analysis ofΦ19 mm steel wire braided hydraulic hose under internal pressure was carried out by using Abaqus nonlinear finite element software.By changing the angles of inner and outer layers of steel wire，the deformation of hose body，tension of steel wire and stress distribution of a fixed-length hose under internal pressure were obtained.It was found that，when the angle was fixed and the internal pressure was over 10 MPa，the deformation of hose body and tension of steel wire increased linearly with increasing the internal pressure.When the angle of two inner layers of steel wire was fixed，the deformation of hose body and tension of steel wire decreased with in-creasing the angle of two outer layers of steel wire. |
