• The dynamic behavior of a two-degree-of-freedom oblique impact system consisted of two pendulums with non-fixed impact positions is investigeated. The relations between the restitution coefficient, the friction coefficient, as well as other parameters of the system and the states before or after impact, are clarified in this oblique impact process. The existence criterion of single impact periodic-n subharmonic motions was deduced based on the Poincar map method and the oblique impact relations with non-fixed impact positions. The stability of these subharmonic periodic motions was analyzed by the Floquet theory, and the formulas to calculate the Floquet multipliers were given. The validity of this method is shown through numerical simulation. At the same time, the probability distribution of impact positions in this oblique system with non-fixed impact positions is analyzed.
