摘要：As the plastic component has the advantage of the lightweight, they are used widely in the industry and many researches are conducted simultaneously; In this study, combined the elastic constitutive model and the fiber orientation, the simulations of the plastic square plate with two material definitions are carried out. They are the orthotropic material and the anisotropic material respectively. Through the simulation comparisons, the anisotropic behaviors on the thermal field, the pressure field and the vibration characteristics of the fiber reinforced PA66 are all analyzed. The results show that the different material definitions have important influence on the structure analysis. It offers the guidance for the design and analysis of the plastic component.
