Abstract
The invention relates to a dynamic operation simulation method and device for a physical system, and the method comprises the steps: obtaining first object state data of a first object and second object state data of a second object in response to a dynamic operation simulation instruction of a target physical system; determining relative speed data based on the first object position data, the second object position data and first preset mapping information; determining target friction force data based on the relative speed data and second preset mapping information; the friction force tends to decrease and then increase along with the increase of the relative speed in the relation between the relative speed and the friction force described by the second preset mapping information; and based on the target friction force data, performing dynamic operation simulation processing on the target physical system to obtain a dynamic operation simulation result. According to the embodiment of the invention, the accurate analysis of the friction force between the first object and the second object can be realized, the construction of a nonlinear friction force analysis model can be realized, and the construction efficiency of an object system can be improved.
