Embodiment Construction

[0034] The invention provides a spherical inertial stable platform with bipolar shaft spherical reticulated shell structure, which includes a platform body, an inner frame, an outer frame, a follower frame, a base and an axle end. Wherein, the inner frame and the base are spherical shells, the outer frame and the follower frame are spherical shells with a hollow structure, and the hollow structure is obtained by hollowing out a grid divided by two orthogonal polar axes of warp and latitude. The centers of these four spherical shells coincide and the nesting sequence from inside to outside is the inner frame, the outer frame, the follower frame and the base; every two adjacent spherical shells are connected by two shaft ends, and The spherical shell located inside rotates around the shaft ends; the table body is located inside the inner frame and is connected by two shaft ends, and rotates around the shaft ends; the base is fixedly connected with the external carrier; wherein, t...

Abstract

The invention discloses a spherical inertial stabilizing platform for a double-polar axis spherical surface latticed shell structure. The spherical inertial stabilizing platform comprises a platform body, an inner frame, an outer frame, a following frame, a base and a shaft end, wherein the inner frame and the base are arranged as spherical shells; the outer frame and the following frame are arranged as the spherical shells with hollow structures; the hollow structures are acquired by hollowing a grid cut by warps and wefts of two orthogonal polar axes and are distributed on the spherical shells other than the shaft end and circuit mounting area. Compared with the stabilizing platform with an annular structure, the stabilizing platform has the characteristic of equal rigidity and is beneficial to the reduction of interference error. Compared with the stabilizing platform with a fully closed spherical structure, the stabilizing platform has excellent heat conduction and heat convection functions and is beneficial to the construction of excellent temperature field.

Description

technical field [0001] The invention relates to the field of mechanical structure design of an inertial stable platform, in particular to a spherical inertial stable platform with a bipolar axis spherical reticulated shell structure. Background technique [0002] The main function of the gyro-stabilized platform is to establish a navigation coordinate system that has nothing to do with the angular motion of the projectile (arrow) according to the given technical indicators, and provide the necessary coordinate reference for the measurement of acceleration and attitude angle. . [0003] The traditional platform structure adopts a ring frame and a rectangular table body. Motors and angle / angular velocity measurement circuits are placed at the joints of the shaft ends of the frame. , it is necessary to increase the size of the frame, so it will occupy a large space for turning, and the volume is large, which cannot meet the current development trend of light and small platform...
