分析了自激振荡射流的偏转特性 ,研究了偏转特性对射流振荡脉冲压力、射流切割性能等方面的影响。实验研究表明 ,自激振荡射流的偏转角可达 9.53°,偏转特性使其振荡脉冲幅值增大 ,频率降低。偏转特性也有效地降低了“水垫效应”的影响 ,提高自激振荡射流的切割性能。
The deflective mechanism of the oscillating water jet is analyzed and the effects of jet deflection on the self oscillating water jet are investigated. It is experimentally shown that the deflective angle may reach 9.53 degree, the pressure fluctuation is more intensive and more regular and the jet can efficiently eliminate the water cushion effect and increase the ability in cutting.
