磨粒几何排列对Inconel 718磨抛的有限元仿真研究OA
Finite Element Simulation Study of the Geometric Arrangement of Abrasive Grains on the Grinding of Inconel 718
目的 为了提高砂带磨抛镍基合金Inconel 718的表面精度,避免砂带上磨屑堆积等问题,针对砂带表面磨粒的顶端结构以及排列方式进行了分析,通过三维动力学仿真方法,研究磨抛过程中磨削力和磨屑的变化情况.方法 开展三种尖端类型磨粒和排列间距、倾角对Inconel 718的磨削机理研究,先分析尖端为点型、线型、面型的磨粒磨削过程,对比不同尖端类型磨粒的切屑形态与磨削力的大小,根据挑选出的点型尖端磨粒建立正四面体磨粒,利用该类型磨粒建立有序与无序的金刚…查看全部>>
Objective To improve the surface precision of nickel-based alloy Inconel 718 during belt grinding and polishing,and to avoid issues such as abrasive grains accumulation on the belt,an analysis was conducted on the top structure and arrangement of abrasive grains on the belt surface.Through three-dimensional dynamic simulation,the variations in grinding force and abrasive debris during the grinding and polishing process were studied.Methods Three types of abr…查看全部>>
