摘要: 为了对1 cm2旋入式铜柱测压器进行分级鉴选,设计一种专用测压试验装置,通过膛内扩容减压的方法,提供满足试验要求的压力源。通过内弹道过程分析,结合腔室流量方程,建立了该测压装置内弹道数学模型。通过仿真,分析了火药燃气在膛内与集气室间的正向流动和回流过程,以及各腔室压力变化过程,分析了高压集气室初始容积、导气孔位置对腔内最大压力的影响。在已知参数条件下,高压集气室内最大压力可调节至约39.0 MPa,与试验结果对比,最大偏差为4.9%,满足旋入式测压器分级鉴选试验要求。

Abstract: In order to distinguish 1 cm2 copper crusher gauge, a special experimental device which can supply required pressure source by volume expansion is proposed and designed. An interior ballistic model of the device is set up and simulated based on the interior ballistic analysis and the flow equation of the working chambers. The pressure and flow characteristics of propellant gas between bore and chamber are obtained. And the influences of initial volume and position of the high pressure chamber on its maximum pressure are studied. The maximum pressure of the high pressure chamber can be adjusted to about 39.0 MPa under the condition of the known parameters. Compared with the experimental results, the maximum deviation is 4.9%. The device can meet the requirement of identifying copper crusher gauge.

Key words: ordnance science and technology, copper crusher gauge, identification, interior ballistics
