为了研究航空薄壁整体结构件高速铣削加工中的整体加工变形,建立了基于ABAQUS/Standard有限元核心求解器的数值仿真系统,并对相关关键技术进行了研究。基于该系统研究了薄壁整体结构件铣削加工全过程,得到了加工过程中应力场、温度场的分布规律,以及加工完成后结构件的整体加工变形规律。通过模拟值与实验值对比,在误差允许范围内模拟结果是可以接受的,为薄壁整体结构件的加工变形分析提供了一种有效的方法。
In order to study the overall machining deformation in high-speed milling of thin-walled monolithic structures, a numerical simulation system based on the ABAQUS / Standard finite element kernel solver was established and the related key technologies were studied. Based on this system, the whole process of milling thin-wall monolithic structure is studied. The distribution law of stress field and temperature field in the process of machining is obtained, and the overall processing and deformation rules of the structural parts after machining are obtained. By comparing the simulated value with the experimental value, the simulation result is acceptable within the allowable error range, which provides an effective method for the deformation analysis of the thin-walled monolithic structure.
