Search method for multi-constrained earth-moon transfer orbit cluster with equal launch intervals

The present invention provides a search method for a multi-constrained earth-moon transfer orbit cluster with equal launch intervals. The method is used for designing n earth-moon transfer orbit clusters meeting multiple constraints and with equal launch intervals within a launch day, and the method takes full advantage of a feature that rocket launch parameters can be adjusted. The method is completed through outer-layer and inner-layer search, and the inner-layer search comprises preliminary search and refine search of a single orbit. A preliminary orbit search algorithm adopts a simulated annealing simplex hybrid algorithm, and a refine orbit search algorithm adopts a class differential correction algorithm. Firstly, preliminary design and search of the orbit are carried out based on an improved conic curve splicing method, an initial orbit parameter value is rapidly calculated, the refine orbit search algorithm is used to carry out refine design on the orbit, and an earth-moon orbit meeting the constraine
