A skin manufacturing post-treatment method for an automobile collision dummy includes: forming a first pouring portion on a skin layer to be treated, and forming a patching recess by grinding the first pouring portion; obtaining an epidermis layer to be treated, and arranging a heating assembly above the patching recess, where the heating assembly is attached to an interior of the patching recess, and the epidermis layer; and simultaneously heating, by the heating assembly, the patching recess and the epidermis layer to be treated. In this way, the epidermis layer to be treated and an inner wall of the patching recess can be simultaneously heated at the first preset temperature, the epidermis layer to be treated and the inner wall of the patching recess are consistent in temperature, and a connection strength between the epidermis layer to be treated and the inner wall of the patching recess is enhanced.

A method for predicting dummy head injury during an automobile collision includes: enabling a dummy head to collide with a rigid flat plate; obtaining a first data set in a collision process; calculating the maximum contact force of the dummy head and the rigid flat plate in the collision process according to the first data set; dividing a duration of the collision process into a plurality of time intervals; and calculating an injury value of the dummy head in each time interval according to the maximum contact force, and selecting the maximum injury value as a target injury value. The method provided by the present application may realize prediction for the head injury under different scene working conditions, and has the advantages of being simple in test flow, and high in prediction precision.
