Abstract
The utility model relates to an impact test device used for an automobile bumper, in particular a novel simulated leg-type impactor. The novel simulated leg-type impactor includes a cylinder-shaped simulated leg; an acceleration sensor mounting seat is fixed on the outer wall of the cylinder-shaped simulated leg; an acceleration sensor is fixed in the acceleration sensor mounting seat; when a test is performed, the acceleration sensor is emitted through an emitter, so that a position at the back surface of the cylinder-shaped simulated leg, where the acceleration sensor is mounted, is made to impact an automobile bumper test piece; and the acceleration of the whole simulated leg-type impactor is obtained through an externally-arranged velocity measuring instrument. With the novel simulated leg-type impactor of the utility model adopted, accuracy of impact directions can be ensured, an emission mechanism and an guide mechanism will not be damaged, and accurate test data can be effectively obtained.
Description
Technical field
The utility model relates to bumper impact test apparatus, guarantees impact direction accurately and effectively obtain comparatively accurately a kind of novel analog leg type knocker of test figure while specifically test.
Background technology
One of important evaluation index because lower leg type impacts acceleration evaluation index in bumper analysis, Project design is by introducing the leg type shock simulation experimental evaluation parts rigidity property of component-level early stage in vehicle development, thereby before car load has been developed, just subitem technical indicator is obtained to Efficient Evaluation and control, be conducive to like this reduce the risk of later development and control cost of development.
Impulse test is conventionally divided into free flight and guiding is impacted two kinds, the test of modular construction impact characteristics adopts guiding flight conventionally, due to the design radian of bumper, in impacting endways, can cause departing from of impact direction, easily damage guiding mechanism, cannot obtain comparatively accurate test figure.
In sum, when the bumper of prior art is tested with impact test apparatus, impact direction meeting depart, easily damages guiding mechanism, cannot obtain comparatively accurate test figure.
Summary of the invention
For the problems referred to above, when the purpose of this utility model is to provide test, guarantee impact direction accurately and effectively obtain comparatively accurately a kind of novel analog leg type knocker of test figure.
For realizing the technical scheme that the utility model object adopts be: a kind of novel analog leg type knocker, wherein: comprise cylindrical shape simulated leg, on the outer wall of cylindrical shape simulated leg, be fixed with acceleration transducer mount pad, in this acceleration transducer mount pad, be fixed with acceleration transducer;
When test, acceleration transducer is launched by transmitter, and the back position that makes cylindrical shape simulated leg that acceleration transducer is installed impacts bumper test specimen, and the acceleration of whole simulated leg type knocker is obtained by external speed measuring instrumentation measurement.
Due to said structure, when test, simulated leg type knocker is free flight, without guiding connection mechanism, obtain the precise information that knockout process effectively contacts the period, carry out computational analysis, simulated leg type knocker is not rigidly connected with trigger mechanism, so can, because later stage direction changes the damage that causes guiding mechanism, not guarantee that impact direction is accurate in knockout process.
Brief description of the drawings
The indefiniteness embodiment that device of the present utility model can provide by accompanying drawing further illustrates.
Accompanying drawing 1 is structural representation of the present utility model.
The structural representation that accompanying drawing 2 is overlooked for the utility model.
Structural representation when accompanying drawing 3 is tested for the utility model.
In figure: 1, cylindrical shape simulated leg; 2, acceleration transducer mount pad; 3, acceleration transducer.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Referring to accompanying drawing 1,2 and 3, a kind of novel analog leg type knocker in accompanying drawing, wherein: comprise cylindrical shape simulated leg 1, on the outer wall of cylindrical shape simulated leg 1, be fixed with acceleration transducer mount pad 2, in this acceleration transducer mount pad 2, be fixed with acceleration transducer 3;
When test, acceleration transducer 3 is launched by transmitter, and the back position that makes cylindrical shape simulated leg 1 that acceleration transducer 3 is installed impacts bumper test specimen, and the acceleration of whole simulated leg type knocker is obtained by external speed measuring instrumentation measurement.
For reducing the rotation of whole simulated leg type knocker in perpendicular, obtain comparatively accurate test figure, in above-described embodiment, preferably: described acceleration transducer mount pad 2 is fixed on the height of center of mass position of cylindrical shape simulated leg 1.
For reducing the oeverall quality of whole simulated leg type knocker, in above-described embodiment, preferably: described cylindrical shape simulated leg 1 is hollow tube.
Obviously, all embodiment of foregoing description are a part of embodiment of the present utility model, instead of whole embodiment.Based on embodiment of the present utility model, those of ordinary skill in the art are not making all other embodiment that obtain under creative work prerequisite, all belong to the category of the utility model protection.
In sum, it when this structural test, is free flight, without guiding mechanism, without guiding connection mechanism, obtain the precise information that knockout process effectively contacts the period, carry out computational analysis, simulated leg type knocker is not rigidly connected with trigger mechanism, so can, because later stage direction changes the damage that causes guiding mechanism, not guarantee that impact direction is accurate in knockout process.
