摘要
介绍了萤火一号(YH-1)、福布斯-土壤火卫一(FGSC)火星探测器组合体进行的联合汽车运输振动试验,联合航空运输降落冲击振动试验,联合发射振动试验和分离试验等联合力学试验的目的、方法、条件和结果。结果表明:YH-1火星探测器在探测器组合体的联合试验中近乎作刚体运动,组合体一阶横向频率约15Hz,一阶纵向频率约30Hz。
The purpose, method, condition and result of the joint dynamic tests of YH-1 and FGSC Mars probe experienced which were the vibration test of the joint ear transportation, landing impact vibration test of the joint aviation transportation, vibration test of the joint launch, and separation test were introduced in this paper. The results showed that YH-1 Mars probe would do rigid motion nearly in the two probe unit. The transverse frequency and longitudinal frequency of one order for the probe unit were 15 and 30 Hz respectively.
