Accompanying drawing explanation
A kind of automobile cylinder collision dynamometric wall of Fig. 1 for providing in the utility model embodiment;
Fig. 2 is the decomposition texture schematic diagram of the automobile cylinder collision dynamometric wall of Fig. 1;
Fig. 3 is that the automobile cylinder collision dynamometric wall of Fig. 1 is used status architecture schematic diagram;
Mark in above-mentioned figure is: 1, backboard is installed, 11, guide groove, 2, triaxial force sensor, 3, installation panel, 4, obstacle support.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model embodiment is described in further detail.
Referring to Fig. 1, a kind of automobile cylinder collides dynamometric wall, comprises the installation backboard 1 of strip, backboard 1 is installed and is provided with along its length a plurality of triaxial force sensors 2, three triaxial force sensors 2, as dynamometry unit, are respectively Fx, Fy, Fz, are covered with from top to bottom whole installation backboard 1.The outer installation panel 3 withstanding shocks that is coated with of triaxial force sensor 2.
Installation panel 3 is U-shaped, and triaxial force sensor 2 is arranged in the groove of U-shaped installation panel 3 and is bolted to connection installation panel 3 of each power sensor setting.
Backboard 1 is installed and is vertically placed, and be connected on obstacle support 4, triaxial force sensor 2 is covered with whole installation backboard 1 from top to bottom.
Backboard 1 back side is installed and is provided with guide groove 11, the wire harness of triaxial force sensor 2 concentrates in guide groove 11.
Triaxial force sensor 2 is connected with installation backboard 1 bolt.
First triaxial force sensor 2 is fixedly mounted on and is installed on backboard 1 by four erection bolts, and then by installation panel 3 by four outsides that are bolted to triaxial force sensor 2, the face shaping of installation panel 3 and size will be equal to original common cylinder collision wall, so what adopt is semicircle concave structure, consider that the power of each sensor do not transmit mutually and disturb simultaneously, and the convenience of installation, sensor dismounting, collision installation panel 3 is consistent with the quantity of sensor, and each power sensor front end loads an installation panel 3.Finally the wire harness of all triaxial force sensors 2 is by installing the backboard 1 unified cabling of guide groove 11 below, and pickup wire bundle is connected to data acquisition unit terminal the most at last.
As shown in Figure 3, before test, the cylinder impact force wall barrier assembling is fixed in impact walls, when vehicle is encountered cylinder dynamometric wall that time, trigger switch by sticking on cylinder impact force wall is to switching signal of data acquisition unit, data acquisition unit starts record data at once, triaxial force sensor 2 values in all dynamometric walls will be recorded, and for follow-up vehicle security, can develop the Data support that provides actual, have greatly promoted the efficiency of research and development of vehicle structure crash-worthiness.
Adopt after above-mentioned structure, be applied in cylinder impact test, by triaxial force sensor 2, all three axial power value records are got off, so that the rear detection of test vehicle collision side collision is stressed and distribution situation.Both can be applied to front post and hit test, and can be applied to again Flank Pole and hit test.Utilize cylinder collision dynamometric wall can effectively measure distribution of force, the crumple of omnibearing understanding vehicle structure and the energy-absorbing situation of vehicle collision side in cylinder impact test process.For the research process of vehicle safety vehicle body design exploitation and crash-worthiness structure provides effective measured test data.
By reference to the accompanying drawings the utility model is exemplarily described above; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or without improving, design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
