摘要: 针对立铣加工系统的刀具子结构和刀柄子结构结合部研究了一种两点结合导纳综合动力学模型。采用导纳综合法研究了两点结合模型的刀尖点位移导纳计算公式。利用Ansys软件进行了刀具子结构和刀柄子结构位移导纳分析,导出位移导纳数据。采用Matlab软件编写两点结合导纳综合法程序,获得了刀尖点位移导纳函数。通过Ansys软件建立了刀具子结构和刀柄子结构整体有限元模型,分析获得了刀尖点位移导纳函数。与两点结合导纳综合法分析结果进行比较,并计算两者相对误差,结果表明:在关注频率范围内相对误差最大为0.7%,试验结果与两点结合导纳综合法分析结果具有很好的一致性。

Abstract: A two points Receptance Coupling Subsystem Algorithm (RCSA) model is proposed at the joint site of tool subsystem and holder subsystem of an end milling processing system. The displacement receptance of tool point was obtained according to the RCSA model. Harmonic response analysis was carried out to get the displacement receptance of tool subsystem and holder subsystem using ANSYS software. Matlab was adopted to write the program of two points RCSA. Data from ANSYS were used to calculate the displacement receptance of the tool point. A finite element model of the system, including tool subsystem and holder subsystem, was established in ANSYS, and displacement receptance of tool point was obtained. The results of the RCSA model and finite element model were compared and relative error of the two models was calculated. The relative error is less than 0.7% in the frequency range concerned. Experiment was conducted, and the experiment results and theoretical results are in good agreement.

Key words: mechanical design, two point coupling, receptance coupling, end milling, tool point
