The invention discloses a method for calculating a simulated leakage rate, which comprises the following steps of: inserting one end of a capillary tube into a simulated cavity, extending the other end of the capillary tube to the outside of the simulated cavity, and filling pressure gas into the simulated cavity through an inlet; and b, calculating the length of the capillary tube required duringleakage according to the mass flow of the capillary tube. Leakage resistance is controlled through the capillary tube, the capillary tube is inserted after the cavity wall of the simulation piece ispunched, flow resistance is adjusted by adjusting the length of the capillary tube, control over local flow loss is converted into control over on-way loss, the tiny leakage amount is simulated and calculated, and the tiny leakage amount can be simulated with high precision. Test cost and test difficulty of the ground performance test of the micro-leakage equipment are effectively reduced.

    本发明公开了一种模拟泄漏量的计算方法,包括以下步骤:将毛细管的一端插入模拟腔体内,另一端延伸在模拟腔体的外部,通过进口向模拟腔体内充入压力气体;b.根据毛细管的质量流量计算泄漏时需要的毛细管长度。通过毛细管控制泄漏阻力,在模拟件腔壁打孔后插入毛细管,通过调整毛细管的长度来调整流动阻力,把控制局部流动损失转换为控制沿程损失,模拟计算微小泄漏量,能够以较高精度模拟微小泄漏量,有效降低微泄漏设备地面性能试验的试验成本和试验难度。
