摘要
针对航天器公路运输、测控装备受火箭发射声波影响2个典型振动场景,利用自研的振动测试系统开展了振动响应试验。在航天器公路运输振动试验中,开展不同路面、不同车速的跑车试验,对比不同位置、不同方向的振动数据,分析了各种运输条件下的航天器振动响应特性,结合实车试验总结了振动规律并给出了运输建议。试验结果表明:运输振动响应与运输车辆的行驶速度、运载对象的质量、运输路面质量状况均有关;不同方向的振动响应呈一定规律,上下方向最大,前后方向次之,左右方向最小。同时,首次开展了火箭发射过程中的声波振动试验,分别监测地面装备受到的空气传播声波振动和声-地震耦合振动,分析了振动规律并给出了装备防护建议。试验结果表明:场区周边设备受空气传播的声波振动影响较大;设备正面所受到的振动影响远大于其他方向且能量集中在相对固定的频段。
This paper carries out a series of vibration response tests by using the self-developed vibration measurement system for two typical vibration scenarios, including spacecraft road transportation and TT&C equipment affected by rocket launch acoustic waves. In the vibration measurement of spacecraft road transportation, vehicle tests on different roads or at different speeds are carried out. By comparing the vibration data of different positions or directions, this paper analyzes vibration response characteristics under various transportation conditions, and, in accordance with vehicle tests, summarizes the vibration law and puts forward transportation suggestions. The test results show that transportation vibration response is related to vehicle speed, weight of the carrying object, and quality of the road surface.Vibration response in different directions shows a certain rule: highest in up and down directions, middle in front and back directions, and lowest in left and right directions. Meanwhile, the acoustic vibration test during rocket launching is carried out for the first time, though which airborne vibration and acoustic-seismic coupling vibration of the ground equipment are monitored respectively. Based on the vibration law, equipment protection suggestions are also given.The test results show that the equipment around the launch site is greatly affected by airborne acoustic vibration. The vibration on the front of the equipment is much greater than that in other directions, and the energy is concentrated in a relatively fixed frequency band.
