准确预估规定试验条件下卫星振动试验所需推力对于试验的设计与实施具有重要意义。文章在常规卫星振动试验需用推力估算方法的基础上,结合具体的小卫星应用实例提出了支反力分析预示法和类比相似结构卫星推力的方法来估算卫星振动试验需用推力。通过与实际振动试验推力数据对比,文章给出了卫星振动试验需用推力估算方法的实用评估结论。
Accurately estimating the required thrust under the required test conditions for the satellite vibration test is of great significance for the design and implementation of the test. Based on the thrust estimation method of conventional satellite vibration test and the application example of small satellite, this paper presents a propulsion method of propulsion analysis and satellite thrust of analogous structure to estimate the required thrust of satellite vibration test. Compared with the actual vibration test thrust data, the paper gives the practical assessment conclusion that the thrust estimation method needs to be used in satellite vibration test.
