摘要
为了预测快速减压环境模拟系统中舱内气体压力下降的时间,依据流体力学孔口出流原理,建立了快速减压近似理论计算模型,并给出了数值迭代计算方法,同时利用有限元仿真方法对压力平衡过程进行分析,搭建了一套试验系统,在不同试验条件下,将两种分析方法得出的结果与试验数据进行对比,验证了计算方法的正确性及可行性。
In order to predict the time of gas pressure drop in the rapid decompression environment simulation system,an approximate theoretical calculation model for rapid decompression was established based on the orifice outflow principle of hydrodynamics,and the numerical iterative calculation method was given.At the same time,the finite element simulation method was used to analyze the pressure balance process,and a set of test system was built.By comparing the results of the two methods with the experimental data,the correctness and feasibility of the calculation method are verified.
