蜂窝材料超声波切割声学系统研究
Research on Ultrasonic Cutting Acoustic System of Machining Nomex Honeycomb Material
摘要
Abstract
According to the principles of ultrasonic machining,a new type of CNC ultrasonic cut-ting spindle of cutting Nomex honeycomb materials was designed.The acoustic horn was designed by the four-end network method,and the acoustic horn was also analyzed and corrected by FEM.The fi-nite element model of ultrasonic acoustic system was established and analyzed.According to the dia-gram,the displacement of horn flange changes little,the output amplitude is larger.The amplitude of the cutter was measured by laser detector,and was worked out a =22·37 μm that meets the process-ing requirements.A large of experiments of cutting Nomex honeycomb materials using the ultrasonic cutting spindle was carried out,and the results are significant:smooth processing surface,high pro-cessing precision,no dust in machining process.关键词
