- 摘要:
- 基于神舟飞船推进系统高压管路测试接口形式,推导出了高压管路测试接口密封堵头拧紧力矩理论计算公式。依据理论计算结果和有限元仿真计算分析,并结合经验校核力矩数值,给出了飞船高压密封堵头拧紧力矩量化数值,即推荐拧紧力矩值[T]=(24±5)N·m,该推荐拧紧力矩值已应用于神舟十一号飞船系统,并通过了飞船飞行考核。
- Abstract:
- Based on the test-port form of high-pressure pipeline for Shenzhou spacecraft propulsion system, the theoretical formula of tightening torque for the sealing-plug was obtained. According to the results of theoretical calculation and finite element simulation analysis, the quantitative tightening torque of the high-pressure sealing-plug of spacecraft is recommended as [T]=(24±5)N·m combined with the empirical checking torque.. The recommended tightening torque value has been applied to the Shen-zhou-11 spacecraft and has passed the flight assessment of spacecraft.
