随着航天科技的发展以及日益增长的性能需求，对卫星的可靠性要求越来越高，对运输过程中的振动也提出了更严格的要求，导致目前的减振系统难以满足未来的运输需求。针对这种情况，设计了基于空气弹簧并联结构的卫星包装运输减振系统，并对其振动特性进行了分析。结合卫星运输箱的结构和减振需求提出了并联空气弹簧减振系统方案。基于实测参数建立了并联空气弹簧减振系统的多体动力学仿真模型，并验证了方案的可行性，并进一步研究了不同运输工况下系统的减振效率及安全性。构建了减振系统进行不同工况下的实车运输测试。研究结果证明基于空气弹簧并联结构的运输减振系统在实车运输中具有较好的减振效率，并可以保证设备在运输过程安全。该研究结果可为大型精密设备运输减振系统的设计提供参考。
Abstract
With development of aerospace science and technology and increasing in performance requirements, the reliability of satellites is required to be higher and higher, and stricter requirements for vibration during transportation to meet are also needed to make the current vibration reduction system be difficult to satisfy future transportation requirements. Here, aiming at this situation, a satellite packaging transportation vibration reduction system was designed based on parallel air spring structure, and its vibration characteristics were analyzed. Firstly, a parallel air spring vibration reduction system scheme was proposed according to structure and vibration reduction requirements of satellite transport box. Then, based on the measured parameters, the multi-body dynamic simulation model of the parallel air spring vibration reduction system was established, and the feasibility of the proposed scheme was verified. The vibration reduction efficiency and safety of the system under different transportation conditions were further studied. Finally, the vibration reduction system was constructed to perform real vehicle transportation tests under different working conditions. The results showed that the vibration reduction system based on air spring parallel structure has better vibration reduction efficiency in actual vehicle transportation and can ensure the safety of the equipment during transportation; the study results can provide a reference for designing large precision equipment transportation’s vibration reduction system.
