Abstract

The invention provides an integrated lightweight electro-hydraulic servo system, which belongs to the technical field of electro-hydraulic servo systems. It has the characteristics of simple structure, small size, light weight, long working time, high reliability, excellent and stable performance, and easy use and maintenance. It can make the missile fly accurately and stably according to the predetermined track. Hydraulic servo system, including: one electrohydraulic energy source, two servo actuators and one servo controller, one electric servo energy source provides hydraulic energy for two servo actuators, each servo controller is responsible for each servo system Control and measurement of two servo actuators and one electro-hydraulic energy source. It is used to realize thrust vector control and aerodynamic control when the missile flies in the atmosphere for a long time.

Description

Integrated lightweight electro-hydraulic servo system technical field The present invention belongs to electrohydraulic servo system technical field, specifically a kind of machine-electricity-hydraulic-pneumatic integration Lightweight electro-hydraulic servo system. Background technique In order to meet the requirements of military warfare in the new era, the full-range atmospheric flight and the full-range mobile campaign tactical guide developed bomb, the only actuator of its guidance and attitude control system is the servo system. According to the task requirements of the model, it is required that the servo system must meet It meets the comprehensive index requirements of "large load moment, high output speed, long working time, compact structure and installation, and harsh working environment". Therefore, there is a need for a compact structure, small size, light weight, long working hours, high reliability, excellent and stable performance and easy to use E...
