运输包装箱的多载荷减振设计研究

目的考虑降低成本,提高效率,面向卫星产品型谱的通用式包装箱设计势在必行。如何确定和选用一种适应于不同载荷特性的减振方案,成为航天器运输减振设计的关键点和技术难点。方法针对这一问题,分析了目标产品的尺寸接口和质量特性,对卫星不同舱段运输工况进行了振动特性分析和试验。结果在此基础上设计了一种适用于3种卫星舱体、4种运输状态通用的包装箱减振分系统,并对装载尺寸参数进行了优化。系统一阶垂向频率不高于5.8 Hz。结论运输试验数据表明新型减振系统对航天产品的减振效果满足要求。

Vibration Damping Design for Multi-load Cargo Container

The work aims to design a kind of general container for satellite product to reduce cost and improve efficiency in view of how to determine and select a damping scheme suitable for different load characteristics has become the key point and technical difficulty in spacecraft transportation vibration damping design. Aiming at this problem, the size interface and weight of the target products were analyzed, and the vibration feature of different transporting conditions of the satellite was investigated and tested. On basis of this, a general shock absorption subsystem for three kinds of satellites and four kinds of transportation conditions was designed, and the loading size parameters were optimized. The first-order vertical fundamental frequency of the system was less than 5.8 Hz. The transportation test data show that the vibration damping effect of the new vibration damping system for aerospace products meets the requirements.
