The utility model content
The purpose of the utility model is that to overcome in the prior art in the automobile side crash test collision dummy simple in structure; The better problem of the defective of anthropomorphic dummy's body structure; Provide a kind of, can imitate the knocker of the side air bag dynamic impulsion test of organization of human body preferably according to the design of ES-II side impact dummy shape and structure.
The purpose of the utility model is to be achieved through following technical proposals:
A kind of knocker of side air bag dynamic impulsion test, the knocker overall fixed is on the seat support backrest plate; Before, during and after knocker is divided into three layers, the emitter of anterior layer and impulse test is fixed, middle level and anterior layer bonding connection, the back layer cover the middle level and with the anterior layer bonding connection, the layer outside, back contacts with the side air bag when impact.Anterior layer is and the surface of contact of emitter, is used for receiving the collision of side impact test; The middle level is a hard rigid material, the bone in the simulation human body; The back layer is soft material, is used to simulate the skin and the musculature of human body, and the back layer wraps the middle level and can simulate the structure of human body preferably.Side point is quick-fried opens at back layer for side airbag, layer contacts with the back.
As a kind of preferred version; The whole imitation of knocker ES-II side impact dummy design, layer top, said back has the outstanding shoulder of outside semicircle, and the shoulder below is the chest of smooth shape; Down for being the belly of inner concavity, layer bottom, back is to be the outstanding buttocks of elliptic arc to chest.The general shape of simulation human body metastomium can more be pressed close to the collision under the actual conditions of human body during test, improved the accuracy of test.
As a kind of preferred version, knocker anterior layer and middle level all are the strip plate body, and the width in middle level is two to three times of anterior layer, and the bottom bending in middle level is extended, the whole L type that forms; Layer bottom, back extends to form simulated person's shank forward at its Width.Second elongated plates simulation human skeleton, the top is the skeleton of trunk, the below extends to the buttocks bone.Layer below, back anthropomorphic dummy's shank has better improved the accuracy of test.
As a kind of preferred version, knocker is provided with the acceleration transducer of the acceleration time curve that is used to measure knocker, and the layer outside, back anthropomorphic dummy's chest place is provided with the measurement crossbeam that is connected with acceleration transducer.Put when quick-fried at the side air bag, measure crossbeam and contact, the stress data and the record of acceleration transducer reception measurement crossbeam with the side air bag.
As a kind of preferred version, anterior layer adopts the scale board material to process, and the middle level adopts wood material to process, and the back layer adopts elastomeric material to process.The scale board material can bear impact force preferably, and plank and elastomeric material can imitate the soft or hard degree of skeleton and skin preferably, and cheap.
As a kind of preferred version, the height of knocker is 600mm-700mm.Simulated the height of general trunk.
As a kind of preferred version, the degree of depth of knocker is 250mm-350mm.The width of impingement area when this degree of depth is greater than or equal to general trunk and contacts with side air bag point is quick-fried.
The beneficial effect of the utility model is, can be provided in the automobile side crash test, comparatively meets organization of human body, and includes the sensor energy measurement and write down the knocker of acceleration time curve, and whole device cost performance is high, and is simple and practical.
