摘　　要：聚氨酯软管应用于空间站某系统,依据空间站在轨长使用寿命要求,长寿命的软管尤为重要,为了能够有效地评估聚氨酯软管在特定工况下的使用寿命,并且分析具体的工作环境对聚氨酯软管泄漏率的影响,通过聚氨酯软管具体实验和公式计算,并对影响泄漏率的工作温度、软管容积进行分析,结果表明温度一定的前提下软管泄漏率随着软管容积的增大而变大,软管容积一定的前提下,软管泄漏率会根据温度的提高而增大,可有效地评估聚氨酯软管在空间站中的使用寿命。Polyurethane tube is applied to space station.According to the requirements of long service life of space station on orbit,long-life tube is particularly important.In order to effectively evaluate the service life under specific working conditions,analyze the impact of specific working environment on the leakage rate.Analyzing the working temperature and the volume that affecting the leakage rate through experiments and formula.The leakage rate of the tube will change with the different volume under the premise of a certain temperature and the leakage rate of the tube will increase with the increase of the temperature under the premise of a certain volume of the tube.This method can effectively evaluate the service life of the polyurethane tube in the space station.
