Zusammenfassung:The invention discloses a dynamic relaxation numerical calculation method and a simulation system.The method comprises the steps that loading grading is controlled through the maximum number of iterations and an iteration precision allowable value, a plurality of sub-loading steps are formed, and in the dynamic relaxation solving process of the sub-loading steps, full displacement in the sub-loading steps is adopted for strain calculation and stress integration; the specific scheme for controlling loading grading is as follows; when iteration is ended based on iteration precision, updating the initial position information based on the target displacement data; updating the initial stress state based on the target stress state; accumulating the total loading step based on the loading step increment; the loading step increment is adjusted based on a preset self-adaptive rule; whether calculation is completed or not is judged based on the updated total loading step; and when iteration is ended based on the numbe
