摘要

结合液体空化理论和制退机非工作腔的空化超声检测与压力测试，研究了制退液的空化效应及其对制退机工作性能的影响。结果表明，在火炮后坐冲击作用下，制退液发生了剧烈的空化效应，后坐结束时非工作腔内充满制退液泡沫，并不存在真空段。制退液泡沫在复进过程中逐渐溃灭，因此在复进“真空消失点”处制退机非工作腔并不提供液压阻力。复进过程中非工作腔提供的液压阻力峰值仅为复进节制腔液压阻力平均值的8.91%。考虑制退液空化效应时，火炮复进液压阻力功比传统理论值小4.5%，火炮最大复进速度比传统理论值大10.5%。试验结果证实了计算结果的正确性。该结论为制退机的合理设计与故障诊断提供了理论依据。

Based on liquid cavitation theory and ultrasonic test and pressure test of recoil mechanism non-working chamber, the recoil oil cavitation and its influence on actual performance of gun recoil mechanism were researched. The results showed that the recoil oil cavitation occurred acutely in the non-working chamber affected by the shock effect of gun recoiling, and the non-working chamber was filled of recoil oil foam instead of was vacuum at the end of recoiling. The non-working chamber didn’t offer hydraulic resistance at the vacuum vanishing point because the recoil oil foam collapsed gradually throughout counter-recoiling. The peak hydraulic resistance in non-working chamber was only 8.91 percent of mean hydraulic resistance in graduating chamber. When taking into account recoil oil cavitation, the counter-recoiling hydraulic resistance work was 4.5 percent less than traditional theoretical value and the maximum counter-recoiling velocity was 10.5 percent greater than traditional theoretical value. The test results confirmed the correctness of the calculation results. The conclusions provided a theoretical basis for the reasonable design and fault diagnosis of recoil mechanism.
