Abstract

The invention belongs to the technical field of angle displacement measurement, in particular to an integrated triple redundancy angle displacement measurement device, and aims at overcoming the defects in the prior art and meeting the requirements for the measurement of a pivot angle of a spray pipe of a novel servo system and feedback control. The integrated triple redundancy angle displacement measurement device comprises a displacement sensor assembly (1), an upper bolt assembly (2-1), a lower bolt assembly (2-2), an adjusting bolt (3), an upper support lug (4) and a lower support lug (5). The adjusting bolt (3) is provided with a left thread and a right thread. The displacement sensor assembly (1) is a potentiometer type displacement sensor made of high-precision conductive plastics. Three resistor assemblies (12) are evenly distributed on three surfaces of a base (11), and electric brushes corresponding to the resistor assemblies (12) are evenly distributed on three surfaces of a brush holder assembly (15). The brush holder assembly (15) is fixed on a connecting rod (14) through shaft end screws. The integrated triple redundancy angle displacement measurement device has the advantages that an integrated triple redundancy design is adopted so that the adaptive capacity to the environment is high, the service life is long, the requirements for the highly reliable angle displacement measurement of the novel servo system and feedback are met according to various tests and evaluations, and the integrated triple redundancy angle displacement measurement device has great significance for improving the reliability of the system, thereby having great popularization value.

Description

technical field [0001] The invention belongs to the technical field of angular displacement measurement. Background technique [0002] In the swing servo mechanism, it is necessary to measure the swing angle of the swing member. The present invention is applied to the measurement of the swing member. The improvement of the swing servo mechanism, the servo mechanism has a compact structure, high integration, and harsh environmental conditions, which determine that the supporting sensor design structure is smaller, more resistant to high temperature, high pressure, strong vibration and shock, higher performance indicators, and better dynamic response. . At the same time, in order to meet the overall demand for the servo system to realize real-time compensation of the engine sinking angle, it is necessary to introduce the nozzle swing angle signal measured by the angular displacement measurement device into the servo closed-loop control system, so the servo system proposes a n...
