摘要

摘要: 耦合载荷分析是航天器研制过程中的一个重要环节, 能够为航天器结构设计, 地面验证试验条件制定以及批准型号发射提供重要依据, 而精确地得到试验验证的航天器动力学分析模型是开展耦合载荷分析的基础. 对于大型复杂航天器结构系统, 动力学模型的试验验证需要统筹安排初始建模、动力学试验、相关分析和模型修正等工作, 这是一项极具挑战的任务. 本文首先给出了结构动力学模型验证的基本流程, 然后重点讨论动力学试验, 相关分析与模型修正等关键技术, 最后结合工程实际的需求, 提出了今后航天器动力学模型试验验证技术研究的重点.

Abstract: Coupled Load Analysis (CLA) is a key step during spacecraft design process, the result of which is the most important reference to structure design, estimation of test force/acceleration specification and the approval of the spacecraft's flight, a test verified dynamic model of the spacecraft is the base of the Coupled Load Analysis. For complex spacecraft system, model verification task is a very challenge. Firstly, a systematic model verification process is presented. And then, several critical issues, including structure dynamics test, model correlation and model updating, are discussed. Finally, according to the space engineering requirement, some emphases that need to research in the future are proposed.
