Problems solved by technology

[0011] This method cannot be combined with whipping test data to quickly identify the chest T1 acceleration A at this moment T1P The reason for the high value, and through the method of computer simulation analysis, it also needs to invest a lot of manpower and time to complete the construction and verification of the model, and finally complete the scheme design, which requires a long cycle and cost

Embodiment Construction

[0067] In order to enable those skilled in the art to further understand the features and technical contents of the present invention, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings and implementation methods.

[0068] Such as figure 2 It is a schematic diagram of an automobile seat neck damage identification system according to an embodiment of the present invention (the data acquisition processor is omitted). figure 2 The global coordinate system of the trolley TC is the X direction and the Z direction; the first position W1 and the second position W2 are the two marked points on the seat back; the third position W3 is the marked point on the seat pan, The third accelerometer is installed at this position, and the x direction and z direction of the local coordinate system of the third accelerometer are consistent with the global coordinate system, that is, x3=X, z3=Z; the fourth position W4 is the ma...

Abstract

The invention relates to an automobile seat neck damage identification method and system. The automobile seat neck damage identification method comprises steps of arranging a first accelerometer, a second accelerometer and a third accelerometer in a seat whiplash experiment, calculating a first moment a maximum neck damage index occurs according to a local X direction accelerated speed time course curve measured by the first accelerometer and the second accelerometer, obtaining a time course curve of a backward displacement of a dummy relative to a seat basin through coordinate conversion and integration conversion according to a global X direction accelerated speed time course curve measured by the third accelerometer and the first accelerometer, determining the displacement of the dummy relative to the seat basin at the first moment according to the backward displacement time course curve, determining a rotation angle of a seat back at a first moment through shooting photos by a shooting device and determining the position of the dummy relative to the back seat at the first moment according to the backward displacement and the rotation angle. The automobile seat neck damage identification method and system provide the basis to the neck protection of the automobile seat.

Description

technical field [0001] The invention belongs to the technical field of automobile safety tests, and in particular relates to a method and system for identifying neck damage of an automobile seat. Background technique [0002] In automobile rear-end collision accidents, 78.2% of the injuries occurred in the neck, and most of these neck injuries were classified as minor injuries. However, due to the lack of understanding of the mechanism of neck injuries, the high incidence of neck injuries and the long-term Symptoms cause patients to suffer great pain and bring huge economic losses to society. Neck protection in rear-end collisions has become an urgent problem to be solved in various countries. For the neck protection of the occupant in a rear-end collision, the seat is the most closely related component to the neck injury, and the design of the seat safety directly affects the occupant's neck protection effect. [0003] In order to better evaluate the protective effect of ...
