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.

Abstract: An integrated MSD connector test device including: a housing; an MSD connector housed in the housing and having a first polarity contact and a second polarity contact, wherein the second polarity contact includes two contact portions separated from each other; a cable extending at least partially outside of the housing, two ends of the cable being electrically connected to the two contact portions respectively; and a first polarity port and a second polarity port accessible from outside of the housing, the first polarity port being electrically connected to the first polarity contact, and the second polarity port being electrically connected to one of the contact portions, wherein the first polarity is a positive or negative, and correspondingly, the second polarity is a negative or positive.
