| 摘 要： | 空间环境效应、制造加工质量以及所承受的工作载荷是诱发航天机构在轨服役过程中潜在故障的影响因素,对其服役寿命和可靠性将产生重要的影响。因此,开展航天机构潜在故障模式与故障机理分析具有重要科学意义和工程价值。本文对航天机构潜在故障的成因、故障模式、故障机理与影响因素之间的关系以及故障的种类进行了论述,梳理了3类15种可能引发航天机构潜在故障的因素,指出由润滑失效引起的摩擦磨损和载荷作用引起的疲劳失效是导致航天机构潜在故障的两个重要原因,并提出了故障机理的分析程序和方法。

| Abstract: | The factors for potential failures in spacecrafts include the effects of the harsh space environment on it during the on- orbit servicing, manufacturing quality as well as the work load during service, which all have significant impacts on its service life and reliability. Therefore, it is of great scientific and technical importance to analyze potential failure mechanism and failure modes in the spacecrafts. In this paper, the types of failures and the relationship of the causes of potential failures, failure modes, failure mechanism and influencing factors for a space structure are discussed. Additionally, fifteen factors classified as three categories that could lead to potential failures of the spacecrafts are presented. It is concluded that the friction and wear phenomena resulted from lubrication failure and fatigue failure related to the loading are two major potential causes of failure in space structure. Pro- cedures and strategies for the analysis of failure mechanism are proposed. |
