| By using micro-mechanics analysis method based on representative volume element theory，the analytical method of orthogonal anisotropic mechanical properties of the braided fibrous framework layer （referred to as braided layer）of the brake hose was derived. The equivalent mechanical modulus was verified by axial tensile experiment of the braided layer. The software of fast modeling and equivalent mechanical properties analysis of the braided layer was developed. Based on the orthogonal anisotropic constitutive equation of the braided layer，a high-precision finite element model of the brake hose was established，and the simulation analysis and experimental verification of the torsion deformation were carried out. The results showed that，the analysis method of orthogonal anisotropic mechanical properties of the braided layer and the simulation method of the torsion characteristics of the hose were reasonable and reliable. |
