Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings.

[0013] like figure 1 As shown, a new redundant electromechanical static pressure servo mechanism includes two sets of speed sensors 1, turbo pump 2, and rectifier 3. The speed sensor 1 is connected to the turbo pump 2, and the turbo pump 2 is connected to the rectifier 3. The first rectifier 3 is connected with the first motor driver 12 and the second motor driver 13 respectively, the second rectifier 3 is connected with the third motor driver 14 and the fourth motor driver 15, and the first motor The driver 12, the second motor driver 13 are connected, the third motor driver 14 and the fourth motor driver 15 are connected to each other, and the first motor driver 12 is connected to the motor 4 of the first servo electric pump 19; the first A of the servo electric pump 19 is connected to the one-way valve 6, the first safety valve 38, the second safety valve 39 and C1...

Abstract

The invention belongs to a thrust vector control servo system for a manned space carrier rocket or missile which has a demand for high reliability to provide thrust for an engine or a steering engine on the rocket or the missile, and particularly relates to a novel multi-redundancy electromechanical hydrostatic servo mechanism. The novel multi-redundancy electromechanical hydrostatic servo mechanism has the advantages that since a servo motor is directly used for driving a bidirectional rotating constant plunger pump, the defect that a valve-controlled electro-hydraulic servo system is apt to be blocked is overcome and the requirement of high reliability is satisfied; since a controller, a motor driver, a servo electric pump and a displacement sensor adopt multi-redundancy configuration, under the situation of at most two-redundancy faults, the system can still work normally and the feasibility of high reliability is guaranteed from structural design; since peak power is provided for a load through the maximum overload of an alternating-current permanent magnet motor and the alternating-current permanent magnet motor is designed according to load average power, compared with an alternating-current permanent magnet motor which is designed according to load maximum power, the size is small, the weight is light and the requirements on long-term use, light weight and small size are better satisfied.

Description

technical field [0001] The invention belongs to a thrust vector control servo system for manned space launch vehicles or missiles with high reliability requirements, to realize the thrust provided by engines or steering gears on the arrows or on the missiles, and specifically relates to a new type of redundant electromechanical static pressure servo mechanism. Background technique [0002] Reliability is the eternal theme of manned launch vehicles. As the actuator of the rocket or missile control system, the reliability of the servo mechanism has always been the short board of the entire control system. [0003] The redundant electromechanical static pressure servo mechanism is a brand-new, revolutionary product with a new design concept that is easy to achieve high reliability. It is the preferred solution for the high reliability servo mechanism of manned space launch vehicles in the future. [0004] The invention proposes redundant (referring to 2 to 4 redundant) electr...
