Abstract
The present invention discloses a kind of calf impact simulation device, comprises impact pole, combined member and acceleration transducer, and the cylinder of impact pole is surrounded with vertical rectangle plane by circular arc camber, is provided with hole for hoist position in the upper end of impact pole; Described combined member comprises member bodies and magnet annulus, and the front end of member bodies is fixedly connected with the middle part of the rectangle plane of impact pole, inlays magnet annulus in the rear end of member bodies, in the annular distance of magnet annulus, establish Piston connecting portion; The rectangle plane of impact pole is established two laterally zygomorphic acceleration transducers of relative rectangle planar central, and the weight ratio of impact pole and combined member is 3:1.The present invention, by the design of impact pole size and structure, can simulate pedestrian shank more really, and this device can Preliminary Simulation shank impact test, and this device can Reusability, reduces experimentation cost.
Description
Technical field
The present invention relates to automobile safety test device, be specifically related to a kind of calf impact simulation device.
Background technology
Along with the maturation of vehicle occupant safety technology, the safety of goers outside vehicle also receives increasing concern, and some external legislative bodies set up special bill for pedestrains safety.By contrast, China starts late in pedestrian's Protective strategy, though actively advocate the protection of automobile manufacturing company reinforcement to pedestrains safety, does not also put into effect compulsory bill at present.Do now the automobile vendor of pedestrian protecting general according to GTR(global technology regulation about during collision of motor-driven vehicles to pedestrian and vulnerable road user more protection and the certification Uniform provisions alleviating grievous injury) and the European safe criticism association of new car of Euro-NCAP() relevant regulations enjoy experiment, the leg fixture of Britain's company designs is all adopted to test, this device is made up of two rigid sections, represent femur (thigh) and the shin bone (shank) of human body respectively, utilize anatomical connectivity two rigid sections of a spring and resistance gauge composition therebetween, to simulate the knee joint of human body, rigid section covers one deck foam outward, in order to simulate the musculature of human body.When using this device to carry out impact test; each test need consume a secondary simulation joint; the a set of simulate muscular of every twice consumption; and the cost of simulating joint and muscle is higher; cause the cost of development of vehicle higher, thus cause a lot of manufacturer under the prerequisite not having mandatory rules of law all to abandon carrying out pedestrian protecting design.
Summary of the invention
The object of the present invention is to provide a kind of calf impact simulation device, its low cost of manufacture, can Reusability, every data demand of initial stage impact test can be reached.
A kind of calf impact simulation device of the present invention, the acceleration transducer comprising impact pole, the combined member be connected with impact pole and be located on impact pole, the cylinder of described impact pole is surrounded with vertical rectangle plane by circular arc camber, is provided with hole for hoist position in the upper end of impact pole; Described combined member comprises member bodies and magnet annulus, one end of described member bodies is fixedly connected with the middle part of the rectangle plane of impact pole, magnet annulus is inlayed at the other end of member bodies, the end face of this magnet annulus parallels with the rectangle plane of impact pole, in the annular distance of described magnet annulus, establish Piston connecting portion; Described acceleration transducer is located on the rectangle plane of impact pole, and the weight ratio of described impact pole and combined member is 3:1, and the rectangle plane of impact pole is established two laterally zygomorphic acceleration transducers of relative rectangle planar central.
Beneficial effect of the present invention is: by the design of impact pole size and structure, can simulate pedestrian shank more really.Magnet annulus coordinates with transmitter, and this device firmly can be connected with impact device before the collision.Can Preliminary Simulation shank impact test by this device, and this device can Reusability, reduces experimentation cost.

Fig. 3 is the A-A sectional view of Fig. 1.
Embodiment
The present invention is further elaborated for connection with figures and embodiment below:
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of calf impact simulation device, the acceleration transducer 8 comprising impact pole 1, the combined member be connected with impact pole 1 and be located on impact pole, the cylinder of described impact pole 1 is surrounded with vertical rectangle plane by circular arc camber, in the present embodiment, the length of impact pole is 200mm, is provided with hole for hoist position 5 in the upper end of impact pole; Described combined member comprises member bodies 2 and magnet annulus 3, the middle part of described one end of member bodies 2 and the rectangle plane of impact pole is welded and fixed, magnet annulus 3 is inlayed at the other end of member bodies, the end face of this magnet annulus 3 parallels with the rectangle plane of impact pole 1, Piston connecting portion 4 is established in the annular distance of described magnet annulus 3, combined member adsorbs fixing by magnet annulus and BIA equipment (hydraulic impactor), the impact bar of BIA equipment is corresponding with Piston connecting portion 4 position; The 7264C type acceleration transducer 8 rectangle plane of impact pole being established two laterally zygomorphic Endevco of relative rectangle planar central produce, calculates the mean value of two acceleration transducers in actual use, ensures the acceleration of data actual response reality.In the present embodiment, device materials selects 45# steel, and carries out blackening process to its surface, and with stiffening device hardness and corrosion resistance, whole installation weight is 8Kg, and wherein the weight ratio of impact pole and combined member is 3:1.
When the present embodiment carries out collision experiment, before this device is lifted on test bumper by hole for hoist position 5 is static, allow the circular arc camber of impact pole in the face of bumper, then make the impact force action of BIA equipment on Piston connecting portion 4, impulsive force overcomes the absorption affinity of magnet annulus 3, this device is made to do free flight, the circular arc camber of impact pole and bumper collision, the data of two acceleration transducer gained on last recording processing impact pole.
