This paper presents a framework for constructing surrogate models for sensitivity analysis of structural dynamics *** models involving deformation,such as collisions,vibrations,and penetration,are devel-oped using the material point *** reduce the computational cost of Monte Carlo simulations,response surface models are created as surrogate models for the material point system to approximate its dynamic *** adaptive randomized greedy algorithm is employed to construct a sparse polynomial chaos expansion model with a fixed order,effectively balancing the accuracy and computational efficiency of the surrogate *** on the sparse polynomial chaos expansion,sensitivity analysis is conducted using the global finite difference and Sobol *** examples of structural dynamics are provided to demonstrate the effectiveness of the proposed method in addressing structural dynamics problems.
