摘要/Abstract

摘要： 针对国内外运动机构准加速寿命试验设计主要集中在部件上,不能反映整机在轨性能的问题,本文对空间二维运动机构的构型和润滑方式进行了分析,确定了空间二维运动机构热真空准加速寿命试验设计中的5大要素和各要素的设计方法,为了考核整机运动性能设计了试验测试内容和测试的方法,并确定了终止试验的失效判据。设计了某空间二维运动机构的热真空准加速寿命试验。通过试验,获得了一系列反映运动机构整机性能指标的试验测试数据,可以根据这些试验数据评估空间二维运动机构的在轨寿命,并且试验结果得到了在轨应用,这说明本文方法有效可行。

Abstract: The domestic and abroad thermal vacuum quasi-accelerated life tests of two-axis gimbals are investigated. It is shown that almost all the tests are focused on the parts rather than on a full gimbal, which can not reflect the performance of the full gimbal. According to the analysis of the structure and lubrication mode of the thermal vacuum quasi-accelerated life tests of two-axis gimbals, the five main elements and their design methods are determined. The test contents and methods are designed for the motion performance examination of a full gimbal, and the failure criterion is given to control the test process. A thermal vacuum quasi-accelerated life test is designed in accordance with the design method of the element design method. A series of test data about the motion performance of the two-axis gimbal is acquired by experiments, which can evaluate the in-orbit life of the space two-axis gimbal. The in-orbit application of the obtained results demonstrate that the designed thermal vacuum quasi-accelerated life test method for the space two-axis gimbal can satisfy the test requirement and it is effective and feasible.
