摘　　要：为了探究高压水射流技术的低温特性,获得高压水射流技术的温升规律,采用单因素的方法进行了一系列高压磨料水射流切割实验,研究了磨料水射流加工过程中的最高温度随靶距和喷嘴移动速度的变化及规律。实验过程中保持压力不变,只改变靶距和喷嘴移动速度,并使用热成像仪对实验过程中的温度进行实时监测。实验结果表明:磨料水射流在加工铝合金时,切断面最高温度会分别随着靶距和喷嘴移动速度增加而增加,并且当靶距和喷嘴移动速度超过一定值时,其最高温度保持在60℃左右。In order to explore the low temperature characteristics of high pressure water jet technology and obtain the law of temperature rise of high pressure waterjet technology,a series of cutting experiments were conducted by the single factor method 9 the maximum,temperature variation with the target distance and the nozzle moving speed in abrasive water jet machining process is studied.During the experiment,the pressure was kept constant,only the target distance and the nozzle moving speed were changed,and the temperature during the experiment was monitored by thermal imager in real time.The experimental results show that the maximum temperature of the cutting surface increases with the increase of the target distance and the nozzle moving speed,and when the target distance and the nozzle moving speed exceed a certain value,its maximum temperature remains at about 60℃.
