摘　　要：喷射成形是快速凝固技术的重要发展方向之一,近年来,静电雾化技术应用到喷射成形过程中,使该技术更加完善,而静电雾化喷射成形装置是该技术的关键技术。本文设计了静电雾化装置,并对喷射成形工艺中静电作用下气体流场进行了模拟,结果表明,静电作用改善了雾化效果,提高了喷射成形产品的质量。Spray forming technology is one of the major development directions of rapid prototyping technology.In recent years,the application of electrostatic atomization in spray forming makes the technology more perfect. Spray forming device of electrostatic atomization is a key technology of spray forming technology. One has been designed and electrostatic interaction on gas flow field in spray forming been simulated resulting in that the effect of atomization improved by electrostatic interaction hence the quality of atomization increased.
