Impacting and friction are always encountered in the mechanical system and make the system experience nonlinearities in both force-position and force-velocity characteristics. In this paper, we propose one effective numerical algorithm for a two-dimensional frictional system involving the impacting by employing the closed form solution to yield the slip responses and extend the closed form solutions for curve length to predict the impacting location and time with high accuracy. By performing the accuracy analysis and robustness analysis through several representative scenarios, we reveal that, (1) the impacting dynamic responses can be predicted through our new algorithm with high accuracy, (2) the accumulative errors of dynamic responses are insensitive to the complex boundary, (3) the new algorithm can keep better robustness when involving repeated impacting.
