Abstract: A simulation method related with the opening force of a front vehicle door after a vehicle frontal collision including: a first simulation step in which deformations of vehicle components which are caused in the vehicle frontal collision to affect the opening of the front door are calculated by simulation; and a second simulation step in which the opening force of the front door after the vehicle frontal collision is predicted by simulation; wherein the components which affect the opening of the front door include a design component and an interface component, the deformations of the design component and the interface component obtained in the first simulation step being used as initial geometric conditions of the design component and the interface component in the second simulation step.
