The invention relates to an automobile seat dummy collision contact force curve acquisition method based on a CAE (Computer Aided Engineering) technology, and belongs to the field of a simulation experiment of automobile seat collision. According to the method, contact membrane elements are established on the outer surfaces of a head, a chest, knees, cruses and double feet of a dummy, the dummy is in contact with a backrest of a front seat by the membrane elements; four specified points comprising two end points of the upper surface of a forefinger, an end point outside the lower surface of a little finger and an end point outside the upper surface of a hand-wrist part are selected on a hand of the dummy, a spatial sphere is established by the four points and is bound with the hand, and the sphere replaces the hand to be in contact with the backrest of the front seat. Therefore, a relatively accurate contact force curve can be obtained. The method is verified by experiments, is easy to implement and has high universality. By the method, anamorphic deformation results of penetration and the like of the body of the dummy and a front barrier in the simulation analysis process can be avoided, and the relatively accurate contact force curve can be extracted; the method has an important significance for early-stage design of an automobile seat.
