Problems solved by technology

However, they are generally only developed and used for a certain type of equipment, and it is difficult to achieve a natural frequency below 10Hz
Therefore, for the low frequency vibration isolation below 10Hz required by some aircraft, the current vibration isolator is helpless

Embodiment Construction

[0014] The technical solution will be described in further detail below in conjunction with the accompanying drawings.

[0015] The vibration isolator includes a shell 1, a transition core 2, a block 3, a rubber block 4, a mounting core 5, a threaded cover 6, a wire mesh pad 7, a spring 8 and a bottom plate 9, and the spring 8 is located on the bottom plate 9 of the shell 1 Above, the interior of the spring 8 is filled with a wire mesh pad 7, the transition core 2 is placed on the spring 8, and the outside of the spring 8 below the transition core 2 is filled with a wire mesh pad 7;

[0016] There is a cavity in the transition core 2, and a rubber block 4 is installed in the cavity. The upper end of the cavity has an internal thread, which is used to fix the rubber block 4 in cooperation with the external thread of the threaded cover 6. A mounting core 5 is fixed on the rubber block 4, and a wire mesh pad 7 is filled between the shell 1 and the transition core 2, and a baffle ...

Abstract

The invention relates to a vibration isolator, in particular to a composite structure vibration isolator with rubber and a wire mesh combined for electronic equipment. Springs (8) are located on a base plate (9) of a shell (1). The springs (8) are filled with wire mesh pads (7). A transition core (2) is placed on the springs (8). The parts below the transition core (2) and outside the springs (8) are filled with wire mesh pads (7). The transition core (2) is internally provided with a cavity. A rubber block (4) is installed in the cavity. An installation core (5) is fixed to the rubber block (4). The parts between the shell (1) and the transition core (2) are filled with wire mesh pads (7). By the adoption of the composite structure vibration isolator, vibration attenuation efficiency is improved, and the structure is simple.

Description

technical field [0001] The invention relates to a vibration isolator, in particular to a composite structure vibration isolator composed of rubber and wire mesh for electronic equipment. Background technique [0002] In order to improve the measurement accuracy, control accuracy, and safety and reliability of photoelectric equipment, aircraft equipment has increasingly stringent requirements for environmental vibration restrictions; and with the increase in the operating speed of aircraft and vehicles, the magnitude of structural environmental vibration is becoming more and more serious. Large, the excitation frequency extends to the low frequency band. According to the vibration isolation theory, the lower the stiffness of the vibration isolator, the higher the vibration isolation efficiency and the better the low frequency vibration isolation effect. Therefore, in order to improve the vibration control accuracy of optoelectronic equipment, it is necessary to reduce the fr...
