本文主要研究了纵向超声振动对筒形件旋压过程的影响。设计并制造了一套可利用超声振动激励的管坯和芯模旋压实验系统。对退火后的AA-6061铝合金预成形件进行了超声振动旋压成形实验。采用模态分析方法研究了系统的振动特性。在径向、轴向和切向方向上测量作用在非振动辊上的成形力。实验结果表明，低功率纵向超声振动可以改善退火后6061铝合金试样的内表面质量。此外，高功率超声振动会影响成形力和材料逃逸。对超声振动下成形力变化的分析表明，这些变化主要是由于超声振动的接触效应引起的。(C)2012爱思唯尔有限公司版权所有。
The main objective of this paper is to study the influence of longitudinal ultrasonic vibrations on the tube spinning process. A robust experimental tube spinning system was designed and manufactured, in which the preform and mandrel can be excited by ultrasonic vibrations. Tube spinning experiments under ultrasonic vibrations were carried out on annealed AA-6061 preforms. A modal analysis was used to study the vibrational behavior of the system. The forming forces acting on the non-vibrating roller were measured in radial, axial, and tangential directions. Experimental results showed that low power longitudinal ultrasonic vibrations can improve the inner surface quality of annealed 6061 aluminum samples. In addition, high power ultrasonic vibrations can affect forming forces and material escape. Analysis of forming forces variations under ultrasonic vibration revealed that these changes are mostly because of contact effects of ultrasonic vibrations. (C) 2012 Elsevier B.V. All rights reserved.
