刀杆的模态分析与改进

Modal analysis of cutter with improvement

在加工圆管过程中,厂家提供的刀杆长度已经不能满足生产需要,根据加工要求必须设计一种满足要求的刀杆,刀杆在运转过程中产生的振动对加工精度影响不容忽视,所以对刀架进行动力学研究是十分必要的,即利用ANSYS前处理软件ICEM对模型进行全六面体网格划分,然后导入ANSYS中进行模态分析,得到系统的固有频率和振型,为改进刀架的性能提供数据支持。

The bend in the processing process, the manufacturers provide the arbor length can not meet production needs, according to requirements to design a process to meet the requirements of arbor, arbor during operation the vibration effect on the machining accuracy can not be ignored, Therefore, the dynamic study of the frame is necessary, namely the use of pre-processing software ICEM model full-hexahedral mesh, then import the ANSYS modal analysis carried out to obtain the natural frequency and vibration mode to improve the knife aircraft performance data to support.
