Fig. 2 is the structural representation of vibration tong;
Mark in above-mentioned figure is: 1, battery; 2, battery bracket; 3, vibration tong; 4, shaking table.
Embodiment
Contrast accompanying drawing below, by the description to embodiment, be described in further detail the specific embodiment of the present invention, object helps those skilled in the art to have more complete, accurate and deep understanding to design of the present invention, technical scheme, and contribute to its enforcement.
As shown in Figure 1, the invention provides a kind of batteries of electric automobile vibration testing device, involving vibrations platform 4, also comprise and being arranged on shaking table 4 and vibration tong 3 for installing battery bracket 2.
Specifically, the shaking table 4 that adopts of this test unit is the same with the shaking table for batteries of electric automobile vibration test of the prior art.As shown in Figure 1, vibration tong 3 is fixedly installed on the table top of shaking table 4, during test, battery bracket 2 is fixedly installed on the end face of vibration tong 3, battery to be tested is installed on battery bracket 2, and need ensure that the center of gravity of shaking table 4, vibration tong 3 and battery is positioned at same vertical line.
As shown in Figure 2, as preferably, the Rectangular Plate Structure that vibration tong 3 is made for aluminum alloy plate materials, battery bracket 2 be bolted be installed on vibration tong 3 end face on.Vibration tong 3 adopts aluminum alloy materials to make, because the specific stiffness of aluminium alloy is comparatively large, make vibration tong 3 on vibration test impact little and transmitting force or performance parameters fine.
As shown in Figure 2, as preferably, vibration tong 3 is provided with two side by side on shaking table 4, and the battery bracket 2 on two vibration tongs 3 and two vibration tongs 3 is specular and arranges.
Present invention also offers a kind of batteries of electric automobile vibration testing method, adopt the batteries of electric automobile vibration testing device of said structure, and comprise the steps:
(1) battery installation steps: be installed to by vibration tong 3 on shaking table 4, are installed to battery bracket 2 on vibration tong 3, are finally installed to by battery on battery bracket 2;
