Example 1:

take the transported equipment as two rows of server cabinets as an example for explanation

The load borne by the equipment meets the requirements shown in table 1.1:

TABLE 1.1

The vibration condition of the road transportation pavement is as follows:

vibration direction: x, Y, Z, respectively;

vibration frequency range: vertical direction of 2Hz-100Hz and horizontal direction of 8Hz-50Hz

Acceleration value: vertical max 3g, horizontal bi-directional max 1.5 g.

Specifically, the road surface test data satisfy the following conditions shown in table 1.2, table 1.3, and table 1.4:

vibration data of road transportation refer to national relevant standard GJB150A environmental test outline of military equipment, and determination of road transportation and vehicle-mounted equipment vibration test specification according to the standard.

Table 1.2 liberation of truck vibration conditions test data 1

Table 1.3 liberation of truck vibration conditions test data 2

TABLE 1.44 tons truck full load vibration test data

According to GJB150.16-1986 military equipment environmental test method vibration test, truck transport environment: the vertical axis total root mean square value is 1.04G, and the longitudinal axis total root mean square value is 0.74G; the experimental magnitude is the power spectral density. And obtaining that the vertical axis of the road transportation environment needs to meet the requirement of the limit value, the transverse axis of the road transportation environment needs to meet the requirement of the limit value, and the longitudinal axis of the road transportation environment needs to meet the requirement of the limit value.

According to the maximum vibration amplitude which can be borne by the provided equipment in the cabinet in the vertical and horizontal directions, and in combination with the analysis conclusion, the following conclusion is obtained:

(1)3 degree of freedom vibration isolation mechanism;

(2) the vertical inherent frequency of the vibration isolation system is 3-5 Hz, and the horizontal inherent frequency is 5-10 Hz;

(3) the damping ratio is more than 0.2;

(4) vibration isolation efficiency (time domain): vertical is more than 70%, horizontal is more than 50%;

it should be noted that, in addition to using the seismic isolation scheme for cabinet transportation provided in any of the above embodiments, the following points should be considered: (1) in consideration of the cable connection between the two cabinets 4, the two cabinets 4 are integrally supported; (2) damping pull rod 3 can be added at the top of cabinet 4, one end of damping pull rod 3 is connected with cabinet 4, and the other end is connected with container 5.

The vibration isolation scheme for cabinet transportation provided by the invention utilizes sine excitation to perform simulated frequency sweep test on a vibration isolation system. For the three-degree-of-freedom vibration isolation system, the three degrees of freedom can move on each degree of freedom respectively by controlling the phase of each vibration isolation position:

(a) the positions of all the vibration isolators are in the same phase, so that independent vertical displacement freedom can be obtained;

(b) the phase difference between the vibration isolator positions on one side and the other side is half period, and independent roll freedom and independent pitching freedom can be obtained.

During the frequency sweep test, under the condition that the inherent frequency is not changed, the frequency sweep simulation experiment is respectively carried out by using the damping ratios of 0.1, 0.15 and 0.2, and the vibration isolation effect of the vibration isolation system under different damping is inspected. The sweep frequency range is 5-200 Hz. The maximum of the responses in the three degrees of freedom of vertical, roll and pitch were obtained, giving the calculations provided in table 1.4.

TABLE 1.4

Through simulation, the following two conclusions can be drawn:

(1) when the excitation is a single sinusoidal signal, the vertical natural frequency is 3Hz, and the damping ratio of 0.15-0.2 is provided, so that the vertical vibration isolation rate of 50% can be ensured when the excitation frequency is at least twice of the natural frequency basically;

(2) on the premise of ensuring the natural frequency of the vertical direction to be 3Hz, the mass center deflection displacement can be controlled within a lower range by vertically matching the damping ratio of 0.15-0.2. The maximum value points of the displacement and the rotation angle of the vibration isolation system under the single sinusoidal excitation are near the respective free degree resonance frequency, and represent the extreme condition of the system response under the single sinusoidal excitation. Since the road spectrum of the packaging vibration isolation system in the actual working environment contains many frequency components, the vertical displacement and the centroid deflection should be smaller than the maximum value of the respective degrees of freedom in table 1.4 in theory. Therefore, the vibration isolation system needs to be subjected to a road surface test to observe the response condition of the vibration isolation system.

The actual road transportation test shows that the road conditions during the actual road transportation test include bumpy roads (as shown in fig. 5-7), express roads (as shown in fig. 8-10), and national roads (as shown in fig. 11-13).

In summary, the vibration isolation device and the vibration isolation method for the electronic information equipment provided by the invention can enable the measured value of the power spectral density of the server to be smaller than the limit value in the specification when the server is transported.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
