Abstract

The invention discloses a spherical inertially-stabilized platform adopting triangular hollowed-out structures. The inertially-stabilized platform comprises a platform body, an inner frame, an outer frame, a follow-up frame, a base and shaft ends, wherein the inner frame and the base are spherical casings, the outer frame and the follow-up frame are spherical casings adopting the evenly-distributed triangular hollowed-out structures, and the triangular hollowed-out structures are approximately equal triangles and are evenly distributed on the spherical casings except the shaft ends and mounting areas. The inertially-stabilized platform has the characteristic of equal rigidity when compared with stabilized platforms adopting annular structures, and reduction of interference errors is facilitated; the inertially-stabilized platform has good heat conduction and heat convection functions when compared with stabilized platforms adopting completely closed spherical structures, and establishment of a good temperature field is facilitated.

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 triangular hollow 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 platforms, and this structure w...
