A Static Balance Tester Based on Air Bearing

Abstract

The invention provides a static balance testing instrument based on an air flotation bearing. The static balance testing instrument comprises a mounting flat board, brackets, air flotation bearings, connection pieces and movement mechanisms, wherein an upper plane and a lower plane of the mounting flat board are planes; the two brackets are located above the mounting flat board; the moving mechanism is arranged between each bracket and the mounting flat board; the air flotation bearing comprises a spherical bowl and a ball; the spherical bowls of the two air floatation bearings are respectively fixedly arranged on the two brackets; the spherical bowls and the brackets are connected to be a whole body; the balls of the two air flotation bearings are provided with through holes passing through a ball center; the both ends of a piece to be measured are fixed with the connection pieces; the two connection pieces respectively penetrate through the through holes on the balls of the air flotation bearings; the piece to be measured, the connection pieces and the balls of the air floatation bearings are connected to be the whole body; and the moving mechanism can be used for horizontally moving the whole body formed by connecting the spherical bowls of the air flotation bearings and the brackets on the upper surface of the mounting flat board, so that the balls of the air flotation bearings are located above the spherical bowls. Compared with the prior art, the measurement precision of the static balance testing instrument can be greatly improved.

Description

technical field [0001] The invention relates to a static balance tester based on an air bearing. Background technique [0002] As a key component of the strategic missile control system, the inertial platform system is the core of the weapon system to achieve precision strikes, and its comprehensive performance is also the key technology to realize the mobility, rapidity, information level and excellent performance of the weapon system. The poor static balance of the platform not only causes the large power consumption of the torque motor to generate heat, which affects the thermal balance of the platform and thus affects the accuracy of the platform. More importantly, during the flight of the projectile, the unbalanced amount will generate disturbance torque on the relevant axis, forming a dynamic error, and ultimately affecting the flight. Drop point accuracy. In the previous generation of strategic weapon platforms, some products were reworked and rebalanced due to out-o...
