| Abstract | The orbital design and optimization problem for space gravitational waves detection is studied in this paper. Firstly, the simplified but sufficiently accurate orbital dynamics model considering the third-body perturbations from Earth, Venus and Jupiter is established. Then, an optimization model with twelve variables in the configuration space is derived with the relative motion and formation design method based on the relative orbital element, while a number of mission requirements are considered in the objective function, such as the arm length rate, breathing angle, and maximum distance between Earth to formation center especially. Afterwards, a hybrid approach of Differential Evolution algorithm and Sequence Quadratic Programming is proposed to optimize the objective function, which is fast in the convergence and robust in the best value. Finally, compared with the LISA designing result, the simulation results demonstrate that the hybrid approach is effective, and can obtain the feasible solution efficiently. Besides, the influence of arm length and initial trailing angle on the stability of equilateral triangle is analyzed, which may have some reference value in the future mission.
