某装置液压阻尼器的阻尼孔试验

Experimental Study on the Damping Hole of Hydraulic Damper in a New Research Launcher

摘要:

发射装置在发射时，产生的强大的后坐力对整个发射装置具有很强的冲击，从而会影响发射装置的性能。舰船设备具有好的抗冲击性能，主要是由于液压阻尼器在发射装置中起到了重要的缓冲作用，从根本上影响了发射装置的持续作战能力以及打击目标的精确性。分析了某新研发射装置中的液压阻尼器，通过运用试验的方法模拟发射装置发射产生的后坐力。分别对 4 种型号的液压阻尼器受到负载冲击产生的缓冲能力进行了测试，将试验数据与理论参数进行比对，最终为某新研发射装置中的液压阻尼器选择了合适的阻尼孔的孔径。

Abstract:

The powerful recoil force produced by the launcher when firing missiles has a strong impact on the entire launcher，which will affect its performance. The hydraulic damper plays an important role in the buffering device of the launcher，which fundamentally affects the sustained combat ability of the launcher and the accuracy of hitting targets. This paper analyzes the hydraulic damper in a new research launcher，and simulates the recoil force produced by the launcher during firing through test. The buffer capacity of four types of hydraulic dampers under load has been respectively tested. Comparing the test data with the theoretical parameters，the appropriate aperture of damping hole for the hydraulic damper in a new launcher has been finally selected.
