| Abstract: |
| This paper aims to study the stress distribution characteristics of advanced reinforced structures under load. The finite element simulation analysis of advanced reinforced structures is carried out to simulate the stress and strain distribution of advanced reinforced structure under uniaxial load, at the same time, advanced reinforcement structural mechanics tests are carried out under uniform loading up to 20 kN at a speed of 0.02 mm/s. The stress and strain levels of advanced reinforced composite structures and metal matrix structures are obtained by strain detection. The finite element and test results are compared and analyzed. The results show that the simulation results of advanced reinforced structure are in good agreement with the test results. Advanced reinforcement structure can reduce the stress level of metal matrix structure results. According to the structure characteristics and load distribution characteristics of aircraft in high stress zone, the reasonable layout of advanced reinforcement structure can improve the fatigue and damage tolerance of this area. |
