根据航天器最近的运输数据研究了喷气推进实验室(JPL)的航天器运输动态环境数据库的修正问题。振动级比1966年测到的要低得多,冲击响应谱大致相同。本文还概括地介绍了喷气推进实验室的地面运送标准以及在防止损伤方面十分成功的运送练习。
The revision of the JPL spacecraft dynamic environment database was studied based on recent spacecraft transport data. The vibration level is much lower than measured in 1966 and the shock response spectrum is about the same. This article also provides an overview of ground handling standards for jet propulsion laboratories and very successful delivery practices to prevent damage.
