中文摘要:
      为了解决飞机复合材料战伤抢修采用机械连接修理法制孔的难题以及修理便携式的要求,研究了基于超声纵振的制孔技术。首先结合钻头及切削刃的运动分析了超声纵振的制孔机理,其次设计了超声纵振制孔系统,重点研究了超声纵振换能器的振动原理,并通过有限元仿真优化的方式设计了换能器结构参数。实验证明,采用这种设计,可有效减少制孔对复合材料带来的分层、毛刺、拔丝等缺陷,同时满足前线机场野战抢修的需求。
英文摘要:
      In order to solve the drilling problem of mechanical repair to the composite materials, the ultrasonic assisted drilling is researched. First, the mechanism of ultrasonic assisted drilling is studied to both the drill and the cutting edge. Second, the portable ultrasonic assisted drilling system is introduced including the hand drill and the ultrasonic power supply. Third, a design of ultrasonic transducer is analyzed with principle and simulation. The experiments show that by adopting this ultrasonic assisted drilling technique, the drilling flaws, such as laminate, burr, wire drawing, etc., can be decreased compared to the direct drilling without ultrasonic, and simultaneously this method can meet the needs of aircraft battle damage repair (ABDR).
