摘　　要：为了将涡环更好地应用到送风等流体输送领域,需要提高涡环生成频率以获得更高的流体输送效率。本文设计一种能够提高涡环生成频率的往复式涡环生成装置,该装置在一个活塞运动周期中可以生成两个涡环,有效地利用了活塞往复运动过程中的推力。针对涡环远距离输送的特点,设计并进行实验;基于响应曲面法与NSGA-II算法对往复式涡环生成装置性能进行多目标优化,使其能够将涡环输送更远距离。结果表明:涡环1与涡环2的输送距离难以同时达到最大值,涡环平均输送距离最大为295 cm,相比优化前增加了2.25%;单个涡环输送距离最大为377 cm,相比优化前增加了6.2%。In order to better apply vortex rings to fluid transportation fields such as air supply,it is necessary to increase the frequency of vortex ring generation to achieve higher fluid transportation efficiency.A reciprocating vortex ring generator that can increase the frequency of vortex ring generation is designed in paper.The generator can generate two vortex rings in one piston motion cycle,effectively utilizing the thrust during the reciprocating motion of the piston.Design and conduct experiments based on the characteristics of vortex ring long-distance transportation;Based on the response surface method and NSGA-II algorithm,multi-objective optimization of the performance of the reciprocating vortex ring generator is carried out to enable it to make vortex rings move longer distances.The results show that it is difficult to reach the maximum moving distance of vortex ring 1 and vortex ring 2 simultaneously.The average moving distance of vortex ring is 295 cm,an increase of 2.25%compared to before optimization;The maximum moving distance of a single vortex ring is 377 cm,an increase of 6.2%compared to before optimization.
