Problems solved by technology

[0003] In previous studies, the pure linear acceleration injury model and the pure angular acceleration injury model are relatively easy to replicate
However, it is very difficult to form compound collision damage, and it is even more difficult to control the proportion of linear acceleration and angular acceleration

Embodiment Construction

[0015] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0016] Such as figure 1 , 2 As shown, the present invention is composed of a base plate 1, a standpipe 2, a stand 3, a steel sheet 4, an active collision plate 5, a passive collision plate 6, a pin shaft 7, a support rod 8 and a fastener 9, etc., wherein the base plate 1 is A square plate, on the bottom plate 1, a standpipe 2 and a stand 3 are arranged along the length direction of the bottom plate, wherein the standpipe 2 is a rectangular tube, and a strip-shaped steel sheet 4 is vertically arranged on the standpipe 2, specifically a steel sheet 4. The left surface of the lower part is in contact with the right plate surface of the riser 2, and the two are fixedly connected by two fasteners 9, and the fasteners 9 can be hoops or other fasteners. In addition, the steel sheet 4 is cut from a spring steel plate.

[0017] The upper end of the steel sheet 4 is...

Abstract

The invention discloses an injury simulation device of a combined injury in vehicle collision. A stand pipe and a rack are arranged on a base plate. a long strip-shaped steel disc is arranged on the stand pipe vertically; the upper end portion of the steel disc is suspended; and an active collision board is arranged at the suspended end of the stand pipe. The rack is at the right of the stand pipe; a passive collision board that is corresponded to the active collision board is arranged on the rack, wherein the passive collision board is in a vertical arrangement. According to the invention, formation of a combined collision injury of a brain of an occupant during the vehicle collision can be accurately and vividly simulated; and a proportion of linear acceleration to angular acceleration can be conveniently controlled and adjusted as well as the device has advantages of ingenious conception and practical structure; therefore, the injury simulation device not only can be used for vehicle collision study but also can be promoted to be applied to fields like sports medicine and criminal research and the like.

Description

technical field [0001] The invention relates to a device for simulating injury mainly used in vehicle collision research, in particular to a device for simulating combined injury caused by vehicle collision. Background technique [0002] In daily life and work, traffic accidents, and sports, the body is vulnerable to damage under some special circumstances. This type of damage includes pure linear acceleration damage and pure angular acceleration damage, and more often, both modes of action exist. compound damage. For example, when the occupant is driving or riding in a vehicle, when a frontal collision occurs while wearing a seat belt, the body will stop due to the effect of the seat belt, and the human head will continue to move forward due to inertia. Rotate downward and reduce the speed of forward movement. When it collides with the instrument, it will form a compound damage of linear acceleration and angular acceleration. [0003] In previous studies, the pure linear ...
