Test barrier appearance size determination method, test barrier, equipment and storage medium

The invention relates to the field of collision test barriers, and discloses a test barrier appearance size determination method, a test barrier, equipment and a storage medium. The external dimension determination method comprises the following steps: determining the heights from a third position of a fourth subarea and a fourth position of a sixth subarea to the ground according to the height from a first position of a front longitudinal beam to the ground, a first scale factor, the height from a second position of a preset vehicle subframe to the ground and a second scale factor, the first scale factor and the second scale factor are determined according to the number of vehicles with auxiliary frames in the preset vehicles; according to a preset collision force distribution cloud picture of the vehicle, the width of a bumper area influenced by front longitudinal beam collision is determined; and determining the width of a fifth subarea based on the width of the bumper area influenced by the collision of t
