Abstract:

Aiming at the uncertainty of the influnce relationship between the parameters of the fixed-point return orbit of manned lunar exploration in the multi-variable and multi-constrained comples parameter space. The parameter sensitivity problem of the fixed-point return orbit of manned lunar exploration is studied. A computational model of the controllable domain of the fixed-point return orbit is established based on the pseudo-perilune parameters, and a global parameter sensitivity analysis method based on the controlled domain analysis is proposed on the basis of the controlled domain analysis. The sensitivity analysis matrix is constructed with the calculated set of controllable domains, and the sensitivity of each parameter is solved by the variance-based method. The general distribution law of the controllable domain of the fixed-point return orbit under the given constraints is obtained by simulation analysis, and the sensitivity index of the pseudo-perilune parameters to the terminal parameters in the controllable domain is given. The relevant findings can provide important references for the analysis and design of future manned lunar exploration orbit missions.

Key words: manned lunar exploration, point return orbit, controllable domain, global sensitivity analysis
