EXPERIMENTAL REASEARCH ON LEAKAGE RATE OF SPACE SEAL WITH O-RING
-
摘要: 通过对硅橡胶材料O型圈在模拟空间环境下的泄漏率实验,研究了空间密封中O型圈的压缩率、温度、O型圈的载荷衰减和原子氧辐射对其泄漏率的影响.实验结果发现,O型圈的泄漏率随O型圈压缩率的增大而减小,在-5——100℃的温度范围内,随温度的升高而增大,而O型圈的载荷衰减和原子氧辐射都对O型圈的泄漏率有不同程度的影响.Abstract: Experimental research on leakage rate of silastic O-ring at simulative space environment is conducted to investigate the effect of compression ratio, temperature, load decay of O-ring and radialization of atomic oxygen on the leakage rate of O-ring. The results show that the leakage rate of O-ring decreases with the increase of compression ratio, increases with the rise of temperature, and it is affected by the load decay of O-ring and radialization of atomic oxygen at various degrees.
