Embodiment Construction

[0027] Attached below Figure 1-7 The present invention is described in further detail.

[0028] The application object of the preferred embodiment of the three-degree-of-freedom anti-shock platform without angular displacement of the present invention is a vehicle-mounted inertial navigation system, according to figure 1 As shown, it is composed of a parallelogram non-angular displacement device 1 and an impact-resistant rubber block 2.

[0029] according to figure 2 As shown, the parallelogram non-angular displacement device includes a lower mounting plate, eight rocker arms 4 , four connecting arms 5 and an upper mounting plate 6 . Wherein the lower mounting plate 3 plays the role of carrying the whole anti-shock platform. The eight holes 7 in the lower mounting plate 3 are first connected with the holes 13 in the four rocker arms. During the installation process, it is necessary to ensure that the rocker arms are parallel to each other, so it can be known that the uppe...

Abstract

The invention belongs to designing and manufacturing of impacting-resistant platforms and relates to a three-freedom-degree angular-displacement-free impacting-resistant platform. The three-freedom-degree angular-displacement-free impacting-resistant platform comprises a parallelogram angular-displacement-free device and an impacting-resistant rubber block. According to the impacting-resistant platform, a rubber elastic component serves as an impacting-resistant buffer, and a parallelogram angular-displacement-free platform serves as an angular-displacement-limiting mechanism. The parallelogram corner-free platform is simple in structure, the vulcanization process of the rubber impacting-resistant rubber block is mature and has been widely used for various types of equipment; and meanwhile, because of the nonlinear characteristics of a rubber material, reliability is high. Because an oblique metal block is used in the buffering rubber block to decompose the impacting energy, buffering under the large impacting load can be achieved.

Description

technical field [0001] The invention belongs to the design and manufacture of an anti-shock platform, and relates to a three-degree-of-freedom anti-shock platform without angular displacement. Background technique [0002] With the development of science and technology, the requirements for inertial navigation in the fields of aviation, navigation, aerospace and national defense are getting higher and higher, and mechanical gyroscopes are gradually replaced by fiber optic gyroscopes, which have been widely used in the above fields. Due to its structural limitation, the rotation direction of each axis is the sensitive axis for measurement. Therefore, under the condition of using the fiber optic gyroscope to measure linear displacement, excessive angular acceleration may affect the measurement accuracy, and even make the gyroscope The gyroscope cannot work normally, so the gyroscope usually needs to work in a relatively stable environment. However, in the field of defense, th...
