摘要
为了实现对薄壁框架零件较高精度的铣削加工,通过基于SHELL单元所组成的有限元模型,在充分提高分析效率的基础上,分析了落刀位置、零件几何尺寸以及切削用量在加工过程中对零件变形的影响,最终对零件的不用切削参数下的变形量进行了分析。最终可以得出结论:采用基于SHELL单元的有限元模型在提高分析效率的基础上,可以对薄壁件的加工过程进行较为系统的优化最终以达到提高薄壁件加工精度和加工效率的目的。
As to milling the thin-wall part accurately,here with the finite element model composed of SHELL elements,the effects of lowering position,size of the part and cutting parameters to the deformations of the thin-wall part were analyzed and compared,and the corresponding theoretical analysis was provided.The conclusions can be got as:the model composed of SHELL elements can analyze the factors causing the deformations of the thin-wall part and optimize the cutting method and cutting parameters effectively to improve the machining accuracy and efficiency.
