Description

[Brief explanation of drawings]

Fig. 1a is a plan view of an equipment mount according to an embodiment of this invention, Fig. 1b is a front view thereof, and Fig. 2 is a state in which equipment is attached to an artificial satellite structure using the equipment mount according to this invention. 3 is an explanatory diagram of the operation of the equipment attachment at high temperatures. Figure 4 shows the heat of the equipment, the satellite structure, and the equipment attachment of the present invention when viewed from the direction of arrow L in Figure 2. 5 is a front view showing another embodiment of the invention, FIG. 6a is a plan view showing a conventional equipment fixture, FIG. 6b is a front view, and FIG. Figure 7 is a perspective view showing equipment attached to the satellite structure using conventional equipment attachments, Figure 8 is an explanatory diagram of the operation of conventional equipment attachments at high temperatures, and Figure 9 is the same as in Figure 7. FIG. 2 is an operation explanatory diagram showing thermal deformation of equipment, an artificial satellite structure, and a conventional equipment attachment when viewed from the direction of arrow L; In the figure, 1 is an equipment fixture, 1a, 1b, 1
c is metal, 2 and 3 are holes or screw holes, A is the distance between metals 1a and 1b of the device mount according to the present invention, B
is the distance between metal 1a and metal 1b of the conventional equipment attachment, 5 is the satellite structure, 6 is the equipment onboard the satellite,
7 is a hole drilled in the device 6 for fixing the device 6, 8 is a bolt for fixing the device 6 to the device mount, 4 is a mounting part that hardly deforms in any direction, and 11 to 13 are this invention. Equipment mount 2 by
1 to 23 are the directions in which conventional equipment fixtures C and 21 are deformed, D is the direction in which 12 and 22 are deformed, E is the direction in which 13 and 23 are deformed, and F and G are the directions in which the satellite structure is deformed, respectively. Vibration direction, J1, J
2 is the height of the strut portions of the materials 1a and 1b after thermal deformation, K2 is the amount of movement of the hole 2 of the conventional device fixture after thermal deformation, and K1 is the hole 2 of the device according to the present invention after thermal deformation. , M is the spacing between the equipment mounting parts of the satellite structure after thermal deformation, N1 is the spacing between the equipment mounting holes after thermal deformation, and N3 is the movement amount of the holes in the conventional equipment mount after thermal deformation. The sum of K2 and the distance M between the equipment mounting parts of the satellite structure, N2 is the sum of the movement amount K1 of the hole after thermal deformation in the equipment mount according to the present invention and the distance M between the equipment mounting parts of the satellite structure, P
is the difference between the interval N1 of the mounting holes of the equipment after thermal deformation and the interval M of the equipment mounting portion of the satellite structure. It should be noted that the same or corresponding parts in the figures are designated by the same reference numerals.
