超声振动辅助磨削CFRP复合材料薄管撕裂损伤研究
Study on Tearing of CFRP Thin Circular Tubes Machined by Ultrasonic Vibration Assisted Grinding
摘要
Abstract
Aiming at the problems of tear damages in the ultrasonic vibration assisted grinding processes of CFRP composite thin tubes with unclear causes,ultrasonic vibration assisted grinding tests were carried out on M55J and T300 composite thin tubes,and the effects of ultrasonic ampli-tude,feed rate and spindle speed on grinding force and tear size were investigated.Through the force analysis of grinding processes and the calculation of the maximum thickness of undeformed chips,the formation reason of tear position and the change law of tear size were analyzed.The results show that the grinding force decreases with the increase of ultrasonic amplitude,increases with the increase of feed rate,and has little correlation with spindle speed.Tear is easy to appear on the inner walls of CFRP composite tubes,and the length and height decreases with the increase of ultrasonic amplitude,increases with the increase of feed rate,and decreases with the increase of spindle speed.关键词
