- 摘要:
- 应用AMESim系统建模和仿真软件并考虑减压阀出口不同节流孔板孔径节流能力,建立了贮箱加注仅为满载加注量40%条件下的系统启动充填过程仿真模型。计算了电爆阀打开后贮箱出口压力变化曲线,获得系统初始充填时间。依据仿真结果结合系统实际情况完成系统冷试验证试验,试验结果与仿真计算数据基本一致。
- Abstract:
- According to throttle ability of different orifice plate at exit of pressure reducing valve, the simulation model of start-up and filling process under the condition of 40% full-load filling quantity was built with the software AMESim. The curves of pressure history at the tank’s exit were calculated after electric explosion valve was opened, and time of the start-up and filling process was obtained. Depending on the simulated results and actual condition of the system, cold test of the system was completed. The test results are coincident with the simulation results.
