Abstract

Single-leg dynamic simulation model of a novel lander was established, and the collision between lander and landing surface was simulated with a nonlinear spring-damper model. In order to improve the simulation accuracy of the model, its stiffness coefficient, damping coefficient and nonlinear exponent were taken as collision parameters and updated based on impact test results of the physical prototype of a lander with a single set of landing buffer. For improving the calculating efficiency, Kriging surrogate model was established to correctly describe the error between simulation results and test results. Then collision parameters were updated using the non-dominated sorting genetic algorithm II and taking minimizing the error calculated with Kriging model as an objective. The modified parameters were substituted into the simulation model to do a new simulation. Comparing calculation results of the simulation model before and after parametric updating, it was shown that compared with the impact test results, the lander’s main body falling distance error is reduced from 19.2% before parametric updating to 5.9% after that, the lander’s jury strut maximum buffering stroke error is reduced from 24.7% before parametric updating to 8.4% after that.
