Description
Technical field
The utility model belongs to automobile safety collision test field, relates to a kind of testing table for dummy's foot rating test.
Background technology
High speed development along with automobile industry, traffic safety is the common issue that countries in the world face, the automotive safety problem is along with increasing day by day of automobile quantity comes into one's own, strengthen the research of automotive safety, reducing the Road Traffic Injury of China, is one of important social concern of the common concern of the whole society and effort solution.As a vital step in the automotive safety research, vehicle impact testing is that all automobile R﹠D processes are necessary, but because this test has danger, destructiveness, so that this test all is by using the dummy to study.
In the middle of impact test, the dummy is true man's substitute, so the dummy need to have true man's physical characteristics, comprises shape, size, quality etc.Dummy's head, chest and foot can be mounted various sensors, in the collision process, these sensors can gather the data such as power, displacement, acceleration, by data acquisition system (DAS) these data are converted to digital signal by Computer Processing, and draw the injury index of parts of body.The researchist just can analyze the injured degree of true man in the traffic accident by these data, and then the security performance of automobile is carried out qualitative assessment.
When head-on crash occurs in human pilot in driving procedure, because inertia, human body has a displacement forward, and the limited space that automobile provides for human foot, therefore the car body component of the foot position such as pedal can be to instantaneous opposition of foot, and this acting force can damage human foot.Therefore, vehicle impact testing need to be tested dummy's foot.And before the automobile real vehicle collision test, because last time test or other reasons, the data of dummy's foot inside may misalignment, therefore need to dummy's foot be demarcated by test, and are in good condition to guarantee dummy's foot.
Present dummy's foot rating test generally is the height of manually controlling a pendulum, then discharge, clash into dummy's foot to obtain data by pendulum, because the pendulum height can't accurately be located, the speed of pendulum can not get accurate control after discharging, so this test operation lacks precision, and waste of manpower.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, a kind of testing table for dummy's foot rating test has been proposed, the testing table that should be used for dummy's foot rating test can be located accurately the height of pendulum and automatically be discharged so that dummy's foot rating test more precisely, more laborsaving.
The purpose of this utility model can realize by following technical proposal: a kind of testing table for dummy's foot rating test, it is characterized in that, this testing table comprises table top and the column that is arranged on the table top, the column upper articulation has the pendulum that can swing in the vertical direction above table top, be provided with the controller that the control pendulum discharges between described pendulum and the column, be provided with one at table top and place dummy foot and pendulum can swing to above-mentioned dummy foot position when pendulum discharges station.
Column is fixed on the table top, and the pin joint that pendulum can center on the column swings.Controller can rise to pendulum the height of setting, reduces human factor, and the control of pendulum height precisely.Place dummy's foot on the station, discharge pendulum by controller and can reduce other external force impact, the speed of pendulum is precisely controlled, pendulum is at perpendicular inner impact dummy foot, obtain accurately test figure, whole process implementation robotization, time saving and energy saving.
Described column has two, is provided with a pole between two columns, and an end of this pole is connected on the root post, and the other end of pole is connected on another root post, and above-mentioned pendulum is connected on the column by this pole.Two root posts guarantee whole stability, and the pin joint of pendulum avoids column to the interference of pendulum movement locus at the middle part of pole.
Described pendulum is connected on the pole by a fork, and turning set is provided with a sleeve on pole, and an end of fork vertically is connected on the outer wall of sleeve, and the other end is connected mutually with above-mentioned pendulum.Pendulum is hinged on the pole by fork, and when pendulum was risen under the control of controller, the radius of movement locus was constant.Fork is connected to the pole middle part by a sleeve, realizes the swing of fork by sleeve.
Described controller comprises a coiler, and the belt ends of coiler can be adsorbed on the electromagnetism suction block on the fork when having an energising, and a column is provided with the switch that can control electromagnetism suction block power on/off.Fork is ferrous materials, can be adsorbed by electromagnet, and when pendulum rose, the electromagnetism suction block was adsorbed on the free end of fork, furls belt by coiler and drives fork.Thereby the outage of switch control electromagnetism suction block discharges pendulum, and the dispose procedure of pendulum is additional without other artificial external force, and the pendulum movement velocity is more accurate.
Also be connected with a crossbeam between described two columns, an end of crossbeam is connected to the upper end of a column, and the other end of crossbeam is connected to the upper end of another root post, and above-mentioned coiler is installed in the crossbeam middle part.Crossbeam can make one-piece construction more stable, and coiler is fixed on the crossbeam middle part of sleeve top.
Described station comprises that one is installed in the cylindrical tray on the table top under the sleeve, and the upper end of tray is fixed with a pallet that is used for placing dummy's foot.After the dummy's foot that makes by tray was placed up, dummy's foot just was the position of pendulum process, and pallet can be so that dummy's foot be placed stable.
Also be provided with one on the described table top for the boss that dummy's thigh is installed, offer mounting hole at boss.Dummy's foot and dummy's thigh are connected as a single entity, and carry bolt on dummy's thigh, and wear mounting hole by this bolt dummy's thigh is fixed on the boss.
Compared with prior art, this testing table that is used for dummy's foot rating test has the following advantages:
1, owing to rising and release by coiler and switch control pendulum, so more robotization of process of the test, the height of pendulum and speed control are more accurate.
2, since pendulum disappear by electromagnetism suction block outage, electromagnetic force, so the pendulum dispose procedure without other artificial external force, test figure is more accurate.
