Motor-driven gas vane servo control mechanism testing device

Abstract

The invention provides a motor-driven servo control mechanism testing device. The motor-driven servo control mechanism testing device comprises an electric steering engine fixing frame, an angle sensor, a sensor bracket, a shell sleeve, a rudder shaft mounting frame and a transmission assembly, and has the following advantages that the structural layout of a steering engine is optimized, a motor shaft is parallel to a projectile body shaft, and the cross sectional area of a projectile body is effectively saved. Direct connection between the angle sensor and a rudder sheet shaft is achieved, and the deflection angle of the rudder sheet is collected more accurately and subjected to feedback control. A limiting relationship is introduced between the sensor bracket and a bevel gear plate so that the rudder sheet can only move within a preset angle. The sensor bracket and a rudder shaft containing table are designed in a split mode, and installation of the angle sensor and the bevel gear plate is facilitated. The whole testing device is simple in structure, safe, reliable and convenient for daily operation and maintenance.

Description

technical field [0001] The invention belongs to the spacecraft control technology, and in particular relates to a test device for a motor-driven gas rudder servo control mechanism. Background technique [0002] Gas rudders are widely used in guided rocket weapons such as ship defense missiles and air-to-air missiles because they can quickly adjust the attitude rotation of the missile body at the initial stage. The gas rudder realizes the thrust vector control of the projectile solid rocket motor through the rudder deflection servo system. The rudder deviation servo system is composed of steering gear, transmission device, gas rudder blade, feedback device and solid rocket motor. Among them, the steering gear, as the core mechanism of the gas rudder servo control system, can be divided into pneumatic steering gear, hydraulic steering gear and electric steering gear according to the classification of energy used. Due to the disadvantages of complex structure and technical dif...

Problems solved by technology

[0003] Most of the existing electric steering gears adopt the vertical cooperation method between the electric steering gear shaft and the missile body. Due to the size requirements of the missile body, the volume of the steering gear needs to be controlled, and the corresponding torque and the volume of the transmission gearbox will also be compressed. , causing the angle control accuracy to be affected to a certain extent
