摘要
深孔加工中镗杆的颤振严重影响孔的加工质量,而振动的抑制与镗杆的内部工作温度有很大关系。文章主要研究镗杆在工作中,温度升高以后对镗杆减振性能的影响。通过对镗杆的结构设计和三维模型的简化,根据热力学第一定律,对镗杆内置减振器振动产生的热量进行分析,运用有限元分析软件ANSYS Workbench,对镗杆进行稳态热分析和瞬态热分析,最后得出镗杆减振效果和阻尼液的温度变化情况。
In the deep hole cutting process chatter of boring bar seriously affects the quality of hole.However,suppression of vibration has very big relations with working temperature of boring bar.This article mainly studied on the performance of vibration isolation after temperature rise in work.Based on the structural design and simplified three-dimensional model of boring bar,according to the first law of thermodynamics,heat generated by the vibration of built-in shock absorber could be analyzed.On the side steady heat analysis and transient thermal analysis of boring bars was analyzed by use of finite element analysis software ANSYS Workbench,finally it concluded the results of vibration absorption and temperature changes of damping liquid.
