Description
Technical field
The utility model belongs to vehicle crash test field, especially relates to a kind of simulating Safety band impact block for central collision dummy breast characteristic research.
Background technology
At present, relevant laws and regulations must wear safety belt when mandatory requirement rides in an automobile.And in the design process of vehicle restraint system air bag and securing band with the use of.When colliding, promise is not fastened the safety belt, and air bag not only can not protect passenger, even can cause extra damage.Therefore, to the wearing situation of securing band and the thoracic injury characteristic research for different position dummy significant.At present, securing band is mainly divided into two aspects to the research of dummy breast damage feature: be the quasistatic impulse test of demarcating based on central collision dummy breast on the one hand; Slide unit and real train test on the other hand.This design mainly uses for the quasistatic impulse test of demarcating based on central collision dummy breast, when leading portion Contact-impact face is for simulating dummy's wear safety belt, and the loading procedure in collision process.
In prior art, for the improper wearing position of securing band in the research of the impact of dummy breast compress variation, impact pendulnm is mainly adopted to carry out the research of quasistatic impulse test, in this study, act on the shock load face of dummy breast for circular, but under normal circumstances, in head-on crash process, the loading force that securing band acts on dummy breast is banded load.Such impulse test is little for male sex dummy's problem, but for Female dummy, due to many two breast, circular impact power just has some and do not conform to actual physical characteristicss response.
Summary of the invention
In view of this, the utility model is intended to propose a kind of simulating Safety band impact block for central collision dummy breast characteristic research, be convenient to dismounting, the banded loading form of securing band can be realized, and the impulse test of different seatbelt wearing position can be studied by this impact block, namely by dummy's seatbelt wearing height with wear angle Two Variables to study, dismounting is quick, stable, and intensity is reliable.
For achieving the above object, the technical solution of the utility model is achieved in that
A kind of simulating Safety band impact block for central collision dummy breast characteristic research, comprise impact portion 1 and the connecting portion 2 of integral type, the shock surface 11 of described impact portion 1 is width is 46-50mm, length is the rectangular surfaces of 260mm, described connecting portion 2 is frame bodies, described connecting portion 2 is provided with and the connecting hole 21 demarcated pendulum and be connected away from the frame center position of impact portion 1, is provided with reinforcement 3 between described impact portion 1 and connecting portion 2.
Further, the vertical sectional shape of described reinforcement 3 is trapezoidal.
Further, described connecting hole 21 is bolts hole.
Further, described reinforcement 3 and be also integrated between impact portion 1 and connecting portion 2.
Further, the width of described shock surface 11 is 48mm.
Relative to prior art, a kind of simulating Safety band impact block for central collision dummy breast characteristic research described in the utility model has following advantage:
A kind of simulating Safety band impact block for central collision dummy breast characteristic research described in the utility model, adopts aluminium alloy integral structure, and not only intensity is large, and quality is light, not easily makes pendulum unstability; The shock surface of impact block is close to the surface of contact of wear safety belt, and load effect is more true; The logical adjustment setting angle of impact block and the upper-lower position of pendulum, the research of this Two Variables independent analysis can be realized, namely to the research of seatbelt wearing diverse location, also can carry out across comparison research for the dummy of different position, different sexes simultaneously.
Accompanying drawing explanation

Fig. 2 is the impact block described in the utility model embodiment and pendulum scheme of installation.
Description of reference numerals:
1-impact portion, 11-shock surface, 2-connecting portion, 21-connecting hole, 3-reinforcement, 4-fastening bolt, 5-pad, 6-impact pendulnm.
Embodiment
It should be noted that, when not conflicting, the embodiment in the utility model and the feature in embodiment can combine mutually.
Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
As Figure 1-Figure 2, a kind of simulating Safety band impact block for central collision dummy breast characteristic research, comprise impact portion 1 and the connecting portion 2 of integral type, the shock surface 11 of described impact portion 1 is width is 46-50mm, length is the rectangular surfaces of 260mm, described connecting portion 2 is frame bodies, and described connecting portion 2 is provided with and the connecting hole 21 demarcated pendulum and be connected away from the frame center position of impact portion 1, is provided with reinforcement 3 between described impact portion 1 and connecting portion 2.
The vertical sectional shape of described reinforcement 3 is trapezoidal, and shock resistance is better on the whole to make impact block.
Described connecting hole 21 is bolts hole.
Described reinforcement 3 and be also integrated between impact portion 1 and connecting portion 2, impact block obtains one-piece member by aluminum alloy materials entirety by machine work, does not have web member, ensure that enough intensity, guarantee not easily to produce deformation when impacting, can not test findings be affected.
The width of described shock surface 11 is 48mm, consistent with most of automotive safety bandwidth, ensure that the accuracy requirement of test.
When the utility model uses, fastening bolt 4 is utilized to be connected with impact pendulnm 6 by the bolt hole on connecting portion 2 impact block, guarantee that impact block is installed firmly in this process, fastening bolt 4 and connecting portion 2 junction are provided with pad 5, prevent fastening bolt 4 pairs of connecting portions from causing wearing and tearing; Test can being carried out according to central collision dummy breast rating test after assembling to arrange, carrying out the upper and lower otherness of simulating Safety band wearing position by regulating pendulum relative to the relative position up and down of dummy breast; The otherness of simulating Safety band wearing position in angle is carried out by the relative angle of adjustment impact block and dummy breast.
Impact block of the present utility model, based on dummy breast rating test platform development, is installed on and demarcates pendulum front end.This impact block is demarcated pendulum by bolt and dummy breast and is connected, and its front end shock surface width is 48mm, and consistent with most of automotive safety bandwidth, length is 260mm, ensure that effective contact area of securing band and dummy breast.Impact block can realize the deflection of above-below direction and angle, can simulate different position dummy when wear safety belt diverse location, dummy breast characteristic, to realize truly reflecting the chest characteristic response of different position dummy when different seatbelt wearing position.
