摘要：

应用连续介质力学有限变形基本理论和超弹性理论，建立钢丝编织胶管的多层圆筒模型，得到了胶管变形和应力分布与内压的关系，分析了胶管的变形、应力分布和破坏强度等力学性能，并且讨论了钢丝层的弹性模量、胶管的轴向伸长等材料或几何因素对其变形、应力分布和破坏强度的影响.

关键词: 钢丝编织；高压胶管;超弹性;破坏强度;力学性能

Abstract:

A three-layer heterogeneous tube is modeled for the fiber braided hoses based on the finite deformation theory of continuum mechanics and the hyper-elastic theory. Relationship between the stresses and the deformation with internal pressure is obtained. Mechanical behaviors such as deformation, stress distribution and failure strength are analyzed. The effect of materials and geometric factors of the hoses such as modulus of the fibers and axial extension of the hose on its deformation and strength is discussed.

Key words: fiber braided; high pressure rubber hoses; hyper-elastic; failure strength; mechanical behavior
