- 摘要:
- 基于ANSYS软件平台，对气路膜片进行了数值仿真，研究了气路膜片等效应力与位移之间的关系，得出了气路膜片材料、几何结构以及结构尺寸设计准则，采用该设计准则设计的气路膜片通过了火工品专用试验台考核。试验结果还表明，气路膜片破裂压力范围为9±0.5 MPa，试验系统氮气加载速率≥100 MPa/s，气路膜片满足设计要求。气路膜片已应用于火工品试验台气体快速加载装置，以模拟药柱燃烧时产生的高温、高压气体快速充填试验系统。
- Abstract:
- Numerical simulation of the pneumatic diaphragm was carried on with ANSYS to study the relationship between equivalent stress and displacement of the pneumatic diaphragm, and then the design criteria of the material, geometric structure and size of pneumatic diaphragm were obtained. The pneumatic diaphragm adopting the design criteria passed the assessment of the special testbed for initiating explosive devices. The test results show that the rupture pressure range of pneumatic diaphragm is 9±0.5 MPa, the nitrogen loading rate of the test system is not less than 100 MPa/s, and the pneumatic diaphragm meets the design requirements. The pneumatic diaphragm has been applied to a rapid gas loading device to simulate the rapid filling test system of high temperature and high pressure gas produced while the grain is burning.
