Embodiment Construction

[0017] The present invention will be further described below in conjunction with accompanying drawing.

[0018] In this embodiment, a gyro sensitive element with a rectangular shape and a mass of 3.8 g is taken as an example.

[0019] Such as figure 1 As shown, the damping structure of the present invention includes a damping unit 1 , an outer frame 2 and an inner frame 3 . The outer frame 2 is rigidly connected to the base of the product structure by screws. As the base of the independent vibration-absorbing structure, it not only requires firm installation, but also has the function of installation reference, which plays a significant role in the performance indicators of the product, such as non-parallelism and cross-coupling. to the regulating effect.

[0020] The inner frame 3 is a square frame whose upper and lower sides are straight sides and two sides are M-shaped. The gyro sensitive element 4 is located in the inner frame 3, and is bonded to the upper and lower str...

Abstract

The invention discloses an independent vibration damping structure of a gyro sensitive element, which includes vibration damping units (1), an outer frame (2) and an inner frame (3), wherein the inner frame (3) is a square frame with upper and lower straight edges and two M-shaped side edges; the gyro sensitive element (4) is positioned in the inner frame (3) and connected with the upper and the lower straight edges of the inner frame (3) and the bosses (31) protruding from the middle parts of the two M-shaped side edges of the inner frame (3); and the vibration damping units (1) are arranged at the contact positions of the outer frame (2) and the two M-shaped side edges of the inner frame (3). In the independent vibration damping structure, by combining the outer frame, the inner frame and the vibration damping units, the gyro sensitive element is suspended on the structural element, so as to enable the gyro to withstand the test of the dynamic environment conditions as impact and vibration on the basis that the performance of the gyro sensitive element is ensured. At the same time, as the inner frame adopts the symmetrical M-shaped structure, the stress externally transmitted to the gyro sensitive element is uniformly distributed, so as to avoid stress concentration.

Description

technical field [0001] The invention belongs to the technical field of vibration reduction control, in particular to an independent vibration reduction structure of a gyro sensitive element used in aerospace. Background technique [0002] Aerospace gyro sensitive components are mainly used to measure the angular velocity of the carrier, and to calculate the attitude of the carrier, navigation and control loops, to achieve the attitude stability and guided flight of the carrier. When the carrier moves, the vibration and bump are severe, the impact is large, and the temperature changes greatly, while the gyro sensitive element is more sensitive, and the anti-vibration and impact resistance are weak. In order to make the gyro sensitive element work normally in the harsh environment, the vibration reduction of the gyro sensitive element Design is especially important. [0003] The existing vibration reduction technology basically adopts the way of integral vibration reduction b...
