The invention relates to the technical field of dynamic visual simulation motion, and discloses a rigid-flexible coupling dynamic simulation method for a unit type roadway hydraulic support under an impact load, which comprises the following steps: S1, according to a final assembly drawing of the unit support, establishing a three-dimensional model diagram of the unit support of the model and importing the three-dimensional model diagram into an ADAMS; s2, constraints of kinematic pairs corresponding to all the components are added in the ADAMS, and the connection relation of all the components is achieved; s3, establishing an impact rigid plate in the ADAMS, and setting impact parameters of the impact rigid plate; s4, the top beam is subjected to flexibility treatment; and S5, carrying out analogue simulation and post-processing to obtain a change result graph of the height of the bracket along with horizontal deviation. By using a digital prototype technology, simulation of a top beam state when the top bea
