Integrated pedestrian protection dummy design method for collision experiment

Abstract

The invention discloses an integrated pedestrian protection dummy design method for a collision experiment, and the method comprises the steps: employing a computer digital model design or a solid object manufacturing method based on the upper body impact structure features of an international passing head-on impact dummy; respectively designing or manufacturing a head, arms, a neck, a chest and a pelvis structure of the pedestrian protection dummy, the pedestrian protection dummy comprising a metal part, a hip joint hinge connecting piece and a pelvis surface rubber part which are arranged in a pelvis, and arranging an angular velocity sensor and a leg impact structural part on the hip joint hinge connecting piece. The leg impact structural part comprises a thigh structural part, a shank structural part and a foot structural part, and then the structural parts are integrated into the whole impact structural body of the head-on impact dummy. According to the method, through the integrated dummy, the impact state and damage to legs and the head in the pedestrian collision process of the vehicle can be recognized through experimental measurement, and deformation of key parts of the whole human body in the collision process and damage to the dummy can also be measured.

Description

technical field [0001] The invention relates to the technical field of vehicle-pedestrian collision experiments, in particular to a design method for an integral pedestrian protection dummy used in collision experiments. Background technique [0002] At present, the current pedestrian protection regulations and NCAP pedestrian protection test and evaluation procedures in various countries in the world basically adopt the human body module impact test method proposed by the European EEVC (European Enhanced Vehicle-Safety Committee) WG10 working group, which divides the human head and legs into two parts. Two different modules, the head impact module (adult and child) impact the hood and windshield, the thigh impact module impacts the front end of the hood, and the leg impact module impacts the front bumper and other parts of the vehicle front . [0003] However, in the process of a collision between a person and a vehicle on the actual road, a series of continuous processes ...
