Abstract—Large amount of simulation work should be done to predict the landing performance of a specific lunar lander before it really lands on the moon and this kind of work is repetitive .To reduce the time consumed and improve the efficiency of analysis, an application of digital integration is discussed in this paper. The proposed integration consists of one module for parametric modeling, one module for landing dynamics analysis, one module for reliability analysis and one module for database management. The creation of a parameterized landing model in the modeling module was discussed in detail seeing that it is the key to realizing the automated integration. Using the method of integrating, the simulation process of the lunar landing was standardized, the design experience was accumulated, and meanwhile, the automation of the simulation process was realized.
