【摘要】:基于Halpin-Tsai方程,引入纤维取向因子,建立了芳纶浆粕纤维增强气压砂轮内橡胶层模量预测模型,描述了气压砂轮基体在动态变化过程中的应力-应变关系。通过ANSYS仿真分析,得出了气压砂轮在不同纤维体积分数下的应力-应变规律,证实了芳纶浆粕纤维增强方法可以改善砂轮基体接触形变缺陷问题。采用混炼法制备了芳纶浆粕纤维增强的橡胶基体,观测到了多维网状纤维微观分布结构,并采用拉伸试验验证了弹性模量预测模型。设计了芳纶浆粕纤维增强气压砂轮加工试验。证明了经芳纶浆粕纤维增强后的气压砂轮可以迅速提升工件表面质量,并使划痕损伤获得一定的控制。
[Abstract]:Based on Halpin-Tsai equation and fiber orientation factor, the prediction model of rubber layer modulus in aramid pulp fiber reinforced pneumatic grinding wheel was established, and the stress-strain relationship of pneumatic wheel matrix during dynamic change was described. Through ANSYS simulation and analysis, the stress-strain law of pneumatic grinding wheel under different fiber volume fraction is obtained. It is proved that the method of aramid pulp fiber reinforcement can improve the problem of contact deformation of grinding wheel. The rubber matrix reinforced by aramid pulp fiber was prepared by mixing method. The microstructure of multi-dimensional reticulated fiber was observed and the prediction model of elastic modulus was verified by tensile test. The processing test of aramid pulp fiber reinforced pneumatic grinding wheel was designed. It is proved that the air pressure grinding wheel reinforced by aramid pulp fiber can rapidly improve the surface quality of the workpiece and control the scratch damage to a certain extent.
