摘要
基于铣削力系数辨识实验,建立铣削力的数学模型。利用有限元动力学分析技术与铣削振动力学数学模型的结合,得到"一"字型薄壁件振幅响应公式和曲线,并对其进行扩展应用于复杂的航空薄壁件。依据主轴转速与工件的固有频率关系,编制出参数化动态特性分析程序,实现航空薄壁铣削参数的优化。
Based on the experiment of cutting force coefficient identification, the mathematical model of cutting force was established. The formula and the curve of the ＂一＂ shaped thin-wall part amplitude responses were obtained by combining finite element dynamic analysis with milling vibration mathematical model and extended to the complex thin-wall parts of aviation. According to the relation- ship of rotate speed and frequency of the workpiece, the program of parameterized dynamical characteristic analysis was programed to realize optimization of the milling parameters of thin-wall part.
