A crash dummy model design method reflecting the dynamic characteristics of the driver's muscles

Abstract

The invention discloses a collision dummy model design method reflecting muscle dynamic characteristics of a driver, aiming at solving the problems of incapability of reflecting real muscle dynamic mechanical characteristics during collision of the driver and low bio-simulation existing in the conventional collision dummy model. According to the method, a current general collision dummy model is used as a basic dummy model. The method comprises the following steps: 1, acquiring muscle signals, i.e., representing a collision scene to promote the driver to produce certain physiological reaction and realize acquisition of the muscle signals under different speeds; 2, designing the muscle dynamic characteristics of the dummy model, i.e., designing muscle static characteristics in the dummy model, obtaining a relation curve of the muscle signals based on speed change through regression analysis according to the muscle signals acquired in the step 1, and calculating the muscle dynamic characteristics of the driver at certain speed so as to design the muscle dynamic characteristics of the dummy model; 3, outputting collision parameters and assessing the bio-simulation of the dummy model.

Description

【Technical field】 [0001] The invention belongs to the field of automobile collision safety, and in particular relates to a design method of a collision dummy model reflecting the dynamic characteristics of driver's muscles. 【Background technique】 [0002] With the rapid development of the automobile industry, automobile safety has gradually become one of the most important indicators for evaluating automobile performance, especially the vehicle occupant collision safety protection technology has become the core competitive technology of products in the domestic and foreign automobile markets and the market standard entry technology . [0003] During the collision process, the driver will produce certain physiological changes, such as muscle tension, etc., but currently in the design process of the car, for the design of collision safety, the dummy model with loose muscles that has been used in the past is still used. An occupant damage evaluation criterion established based...

Problems solved by technology

[0007] In order to solve the problem that the existing collision dummy model cannot reflect the dynamic characteristics of the muscles of the real driver when the collision occurs, the existing collision simulation method based on the collision dummy cannot accurately describe the dynamic changes and physiological changes of real human beings in actual traffic accidents. The problem of collision injury, the present invention provides a kind of collision dummy model design method that reflects the driver's muscle dynamic characteristics, this method uses the current common collision dummy model as the basic dummy model, carries out the design of muscle dynamic characteristics to it, designs The method is simple, and by using this method, a dummy model for the crash test that reflects the dynamic characteristics of the muscles of the real driver when the collision occurs can be designed to improve the biological simulation of the crash dummy model and further improve the crash safety performance of the car
