Abstract

The invention discloses a simulated analysis method for suspended potential of a low earth orbit satellite. The simulated analysis method includes: acquiring environment parameters of a low earth orbit space, state parameters of a solar array and material information of the satellite; building a dynamic simulation model according to the environment parameters, the state parameters and the material information; carrying out number analog computation on the dynamic simulation model to obtain the suspended potential of the satellite model; calculating the suspended potential of the satellite based on the dynamic simulation model through particle simulation number analyzing method. The simulated analysis method for the suspended potential of the low earth orbit satellite is capable of effectively improving the calculation accuracy.

Description

Technical field [0001] The invention relates to the field of aerospace technology, in particular to a simulation analysis method for the suspension potential of a low-orbit satellite. Background technique [0002] The solar array power system is one of the most important payloads of the satellite. Because it is completely exposed to the space plasma environment, it is susceptible to the impact of the space charged environment and collects the current in the space plasma environment, causing the potential of the satellite structure to change. Changes in the structural potential of the satellite will cause discharge events and affect the normal operation of the load on the satellite, such as causing errors in the detection data of the space environment detection load, and causing the burning of the high-voltage solar array. In the satellite design stage, it is necessary to carry out the analysis of the floating potential according to the space environment in which it operates, so a...
