摘要
针对一般方法增加深孔加工镗刀刀杆静刚度的局限性,采用了一种新颖的增加刀杆动刚度的思维方法,对内藏式减振刀杆进行了设计.在多体动力学理论基础上,利用软件ADAMS以及ANSYS构建了集成的系统平台.在此基础上,对重型数控机床深孔加工动力减振镗杆的设计进行了仿真验证.仿真结果表明,该设计能够有效地提高刀杆的动刚度,减小刀具径向跳动量,提高表面加工质量.
Aiming at the limitations of the way to increase the static stiffness of the boring bar, this paper adopts a novel thinking way that aggrandizes the dynamic stiffness of the boring bar to design a bar with a vibration absorption system in the boring bar. This article uses advanced software——ADAMS and ANSYS to build the integrated system platform based on theory of Dynamics of Multi - body System, and validate the accuracy of the design for heavy NC machine tools dynamical vibration absorption boring bar for deep - hole processing. The result of simulation demonstrates that the design can enhance the dynamic stiffness of the boring bar, reduce the quantity of radial vibration and improve the surface processing quality.
