摘要/Abstract

摘要：

针对塑料模具在玻璃纤维冲蚀下造成的表面磨损问题，运用有限元软件ANSYS/LS-DYNA建立了模具材料多颗粒冲蚀有限元模型，进行三维显式冲击动力学计算，研究纤维在不同冲蚀速度和冲蚀角度下对模具的冲蚀规律，分析冲蚀机理。结果表明，玻璃纤维对模具的冲蚀过程以微切削为主；玻璃纤维对模具的冲蚀磨损率随着冲蚀速度的增加而增加，随着冲蚀角度的增加而呈现先增加后减小的趋势。

Abstract:

The surface erosion wear of plastic mold caused by the impact of glass fibers was studied. The finite element software ANSYS/LS-DYNA was employed to study the erosion process. A multi-particle erosion finite element model was established and a three-dimensional explicit impact dynamic scheme was carried out to analyze the erosion of the mold under different impacting velocities and incident angles to clarify the erosion mechanism. The results showed that the erosion of glass fibers to the mold was dominated by micro-cutting, and the erosion rate increased with the rising of impacting velocity and tended to rise and decline with the increasing of incident angle.
