Abstract

The utility model relates to an electric liquid load simulator for simulating aerodynamic moment on the rudder surface of a flying vehicle and overcoming redundant force, which is composed of a base, a loading motor, an object motor and a sensor frame. The utility model is characterized in that a position synchronous motor is arranged between the base and the loading motor, so that the synchronous motor can be moved synchronously along with a loaded object; accordingly, position movement and loading which are commonly born by the loading motor can be respectively born by the synchronous motor and the loading motor, the loading motor only bears the loading task, and position disturbance which acts on the loading motor is close to zero, so that the influence of the redundant force can be eliminated, and the frequency span of a loading system can be enhanced. The utility model can enhance the loading precision of the load simulator and the accuracy of ground loading experiments.

Description

Electrohydraulic load simulator
The utility model relates to a kind of electrohydraulic load simulator that is used for the suffered aerodynamic couple of simulated flight device rudder face, overcomes redundant force.
Load simulator is the charger of simulated flight device suffered aerodynamic couple of rudder face in flight course, is typical passive type force servo system.Redundant force is owing to be loaded the object active movement, produces at loading motor (oil cylinder) two load cavities and forces flow, forces pressure thereby produce, and is exactly redundant force by the power output of forcing pressure to produce, and the existence of redundant force has a strong impact on loading accuracy and system's frequency range.Redundant force is the function that is loaded the object rotating speed, and the value of the high more redundant force of speed that is loaded object is just big more.Thereby, overcoming redundant force is the key of load simulator design, existing overcome the load simulator redundant force and mainly take measures to overcome redundant force from hardware, as to loading parameters of hydraulic motor optimal design, double valves compensation scheme, latch plate correcting scheme etc., though certain effect is all arranged to overcoming redundant force, but all there is certain defective, still can not satisfies actual requirement.
The purpose of this utility model is that a kind of improved electrohydraulic load simulator that can overcome redundant force will be provided, and improves the loading accuracy of load simulator and the accuracy of ground loading experiment.
The technical solution of the utility model: between the loading motor of load simulator and support, introduce position synchronous compensation motor, when the carrying object motion, syncmotor one steering wheel is synchronized with the movement and makes that loading the motor corner approaches zero, act on the position disturbance that loads on the motor thereby eliminated, reached the purpose that overcomes redundant force.Because of the work corner that loads motor approaches zero, the cavity volume that loads motor is reduced, so the frequency range of loading system also is improved.
Enforcement of the present utility model is for the loading accuracy that improves load simulator, the accuracy that improves the ground loading experiment has important techniques to be worth and practical significance, and can be generalized in aircraft rudder surface loading and the naval vessel rudder face loading experiment, therefore social effect is widely arranged.
Below in conjunction with embodiment and accompanying drawing thereof the utility model is specified.
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1 support, 2 pots, 3 sensor frames, 4 electrohydraulic servo valves, 5 syncmotors, 6 dead rings, 7 connectors, 8 shaft couplings, 9 shaft joints, 10 pots, 11 load motor, 12 electrohydraulic servo valves, 13 dead rings, 14 bearings, 15 aiding support covers, 16 torque sensors, 17 inertia dishes, 18 dead rings, 19 object motors, 20 electrohydraulic servo valves, 21 sensor frames, 22 pots.
As shown in Figure 1: the utility model comprises by support (1), load motor (11), object motor (19) and sensor frame (3,21) form, it is characterized in that at support (1) and load introducing position synchronous compensation motor (5) between the motor (11), in syncmotor (5), load motor (11), the object motor is equipped with electrohydraulic servo valve (4 on (19), 12,20) and dispose pot (2,10,22), pass through by dead ring (6) between syncmotor (5) and the loading motor (11), connector (7), shaft coupling (8) and shaft joint (9) setting-in mutually connect, and load between motor (11) and the object motor (19) by dead ring (13,18), bearing (14), aiding support cover (15), torque sensor (16) and inertia dish (17) setting-in mutually connect.When the carrying object motion, syncmotor (5) be loaded object (steering wheel) and be synchronized with the movement, make that loading motor (11) corner approaches zero, act on the position disturbance that loads on the motor (11) thereby eliminated, reach the requirement that overcomes redundant force, because of the work corner that loads motor (11) can significantly reduce (can reduce by 90%) than ordinary load motor, the cavity volume that loads motor (11) is also reduced, thereby improved the frequency range of loading system.
