Stress analysis reinforcement textile of hose by the particle simulation method

摘要

The design of the hose reinforcement textile is important when we develop the oil pressure hose. It was limited to the macro-analysis that modeled the whole thread layer with the stress analysis of the Finite-Element Modeling. It was possible to the micro-analysis with the model that connected the spherical condition. Deformation of the reinforcement textile of hose has been simulated by using a textile model of twisted threads and the Particle Simulation Method. Each thread is modeled with 7 filaments which are constructed with spring-connected spheres. The motion of each sphere is calculated by solving the translation and rotational motion equations under the stretching and twisting deformation of the hose. The total forces exerted in the reinforcement textile by stretching and twisting were in good agreement with experimental measurements.
