Abstract

The invention discloses a system and a method for calibrating impact on feet of a dummy for automobile collision, and belongs to the field of automobile safety detection. The system comprises a vertical type bracket, a dummy foot fixing table and a foot impact device, wherein the foot impact device comprises a rotating shaft, a swing hammer system, an acceleration sensor and a data acquisition system. The method comprises the following steps of: arranging the feet of the dummy on the foot fixing table below the vertical type bracket; lifting a swing hammer by a certain angle, so as to enable the swing hammer to freely swing and impact the feet of the dummy, and recording an impact acceleration and an impact force at ankles of the swing hammer by the data acquisition system; comparing the measured impact acceleration of the swing hammer and dummy foot stress data with dummy foot calibration standard data; and making a calibration judgment on the feet of the dummy according to a comparison result. The system has a simple structure and is low in cost; and the feet of the dummy can be calibrated all around.

Description

technical field [0001] The invention relates to the field of automobile safety inspection, in particular to a dummy foot impact calibration system and method for automobile passive safety tests. Background technique [0002] In the study of passive safety of automobiles, the automobile crash test is the basis. Through the experiments, the movement and deformation of the vehicle in the accident, the response of the human body, and the interaction between the human body and the vehicle components are studied, so as to study the methods that are beneficial to human safety. The dummy must carry out various calibration tests specified in the regulations on a regular basis. If the calibration results are not met, the physical properties of the dummy need to be adjusted. Therefore, the calibration of the dummy is very important for obtaining the test results correctly. Hybrid Ⅲ 50% male dummy is currently widely used in automobile crash test. With the continuous deepening of resea...
