Abstract

The invention discloses an evaluation method and device of automobile front collision performance. The evaluation method includes: detecting acceleration of an automobile to acquire an acceleration and time relation curve of the automobile; calculating and acquiring a speed and time relation curve of the automobile according to the acceleration and time relation curve; calculating a safety value of the automobile according to the speed and time relation curve; judging whether a body structure of the automobile meets preset front collision safety requirements or not according to the safety value. The evaluation method is simple, high in stability, less prone to being affected by single factor, more accurate and more complete in evaluation on rigid barrier-avoiding front collision performance, convenient for optimizing the body structure of the automobile and conducive to shortening development period and lowering number of sample automobiles and development cost.

Description

technical field [0001] The invention relates to the technical field of automobile safety, in particular to an evaluation method for automobile frontal collision performance and an evaluation device for automobile frontal collision test. Background technique [0002] Along with increasing day by day of automobile, the frequency that automobile traffic accident takes place in driving process also increases greatly. The survey shows that the front of the car is a high-incidence area of ​​collision accidents, and is a high-risk area for the safety of occupants. Therefore, it is of great significance to study the safety of frontal collision of automobiles to reduce the injuries of people in traffic accidents. In order to quantitatively distinguish the safety performance of different cars, my country has issued the C-NCAP (China-New Car Assessment Program, China New Car Assessment Program) evaluation rules. [0003] According to C-NCAP, the vehicle frontal crash test is set up. ...
