A Design Method of Dummy Model for Crash Test Reflecting the Driver's Protective Attitude

Abstract

The invention discloses a dummy model design method for a crash test reflecting a driver protection posture to solve the problems that an existing dummy model cannot reflect protection postures like bending and stretching of limbs of a driver when a crash happens and is not high in biological simulation. The dummy model design method for the crash test reflecting the driver protection posture comprises the following steps that protection postures are collected, a crash site is reappeared so as to enable the driver to generate protection postures and achieve the collection of the protection postures at different vehicle speeds; dummy model parameters are designed, the dummy model parameters are designed correspondingly through confirmation of the limb length and joint positions of the driver; the dummy model protection postures are designed: the protection postures of the dummy model when the crash happens is designed; crash parameters are output: display of limb motion of the dummy model during the crash process is achieved, crash parameters are output and displayed, and evaluation is conducted on the biological 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 dummy model for a collision test reflecting a driver's protection posture. Background technique [0002] With the progress of our country's economy and the rapid development of the international automobile industry, it is extremely important to effectively suppress or reduce the damage to car occupants caused by traffic accidents from the perspectives of enterprise market share, consumer life and property protection, and social and economic stability. role. [0003] Since the 1980s, most of the international automotive engineering field has used dummies (such as Hybrid III dummy made of metal and plastic materials) for computer simulation of traffic accidents, crash experiments of trolleys or real vehicles, and passed the test in the dummy. The acceleration, displacement or force of each position of the person can be used to evaluate th...

Problems solved by technology

[0007] In order to solve the problem that the existing collision dummy model cannot reflect the protective posture 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. For the problem of collision injury, the present invention provides a dummy model design method for a collision test that reflects the driver's protection posture. The method is simple, and by using this method, a dummy model for a crash test that reflects the protective posture of a real driver when a collision occurs can be designed, which improves the biological simulation of the crash dummy model and further improves the crash safety performance of the car
