| 摘 要： | 为解决超声清洗中超声设备性能的评价,以及工程应用中超声强度的选取和控制问题,提出了一种根据声功率大小来测定声场强度的评价方法。制作了一个专门的超声清洗系统,并用瓦特计法测定清洗液中得到的声功率,同时用一个探头从清洗液中提取信号;通过测量清洗液中的声功率与探头输出信号电压间的关系,用数字形式来显示超声场强度。用此法对不同清洗槽进行测量,结果表明,该方法可以作为工程中大功率超声场的一种评价方法。

| Abstract: | Based on measurement of acoustic power in liquids an intensity evaluation method for ultrasonic fields is proposed to satisfy practical needs in evaluating ultrasonic cleaning equipment, and controlling ultrasonic intensity. For this purpose a special cleaning system is made. Acoustic power in the liquid is measured with a Watt meter. Ultrasonic intensity is measured with a probe, and displayed digitally. This is achieved by investigating relationship between the probe output and the radiated acoustic power. Experimental results with several commercial cleaning machines show that the proposed evaluation method is practical. |
