The load simulator has the advantages that the structure is simple, the installation is convenient, the hardware configuration number is small, and complicated active loading devices can be replaced.

Description

The passive loading steering wheel of loading gradient servo-actuated load simulator
Technical field
Patent of the present invention designs the passive loading steering wheel of a kind of loading gradient servo-actuated negative analog experimental provision, specifically designs a kind of angular motion steering wheel aerodynamic loading simulator.
Background technology
Usually to carry out flight control emulation and experiment on the ground before aircraft is taken a flight test,, need configuration steering wheel load simulator to carry out simulation test usually in order to simulate the steering wheel actual working environment.
The steering wheel load simulator is also claimed the steering wheel loader.Steering wheel loads according to working method and is divided into initiatively loading and passive loading dual mode.
Initiatively to mainly contain shortcoming following for the loading simulation device: at first; Be that electronic loading or hydraulic loaded form all can produce unnecessary moment; Be load mode inherent shortcoming initiatively, the unnecessary moment that especially under little loading gradient situation, produces even can flood useful load signal.Secondly, initiatively load mode requires the expenditure of energy, and especially loading for fast big load needs to adopt the hydraulic loaded mode usually, and the hydraulic pressure loading device cost is high, complex structure and easy care not.
Passive loading simulation device adopts implementations such as weight block (or inertia piece), flexibility bar usually.Passive loading does not require the expenditure of energy, and can not produce unnecessary moment yet, and easy care simple in structure.But existing its major defect of passive load mode: at first, weight block (or inertia piece) is a constant load; Secondly, though the flexibility bar working method along with load changes with angle of rudder reflection, loading gradient is invariable and the angle of rudder reflection variation range is limited.
Through above two kinds of steering wheel loader simulator shortcomings having been carried out analysis targetedly; Patent of the present invention is fully solving on the basis that has shortcoming now and is carrying out the brand-new design on the principle; The passive loading steering wheel of invention a kind of loading gradient servo-actuated of design negative analog experimental provision; Its loading gradient has realized online adjustable, can follow the tracks of and Simulated Aerodynamic Loads.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, easy for installation, cost is low, Hardware configuration quantity is few, can satisfy the loading system of multiple model steering wheel load simulation.Its principal character is: gathering sill (1), servomotor (12) and bearing (9) are fixed on the work top; Wherein distance rod (2), gear (3), flexibility bar support (4) are fixed together with gathering sill (1) with fixing slide block (6); Speed reduction unit (7), torque sensor (8), shaft coupling (10) and steering wheel are connected with bearing (9) then, are connected with distance rod (2) through slow down (7) simultaneously.Servomotor (12) is connected with rack provides device power.Whole steering wheel simulator apparatus has been realized: (1) wide scope of application.Through selecting the different size speed reduction unit for use, can simulate the heavy load scope; (2) low energy consumption.
Patent of the present invention discloses a kind of aerodynamic loading and simulates passive loading experimental apparatus, and its characteristics are:
(1) adopt flexibility bar 5 to carry out passive loading;
(2) increase the load simulation scope through speed reduction unit 7, also increase the test angle range simultaneously;
(3) pass through the fixedly to-and-fro movement real time altering loading gradient of slide block (6) device;
(4) through the fixedly to-and-fro movement of slide block (6) device, real time modelling steering wheel aerodynamic loading;
(5) acted on fixedly on slide block (6) device by a pair of tooth bar distance rod, the to-and-fro movement that makes fixing slide block (6) install is a balanced load.

Concrete principle of work
At first, select speed reduction unit according to steering wheel angle of rudder reflection variation range.When steering wheel moved, flexibility bar will produce torsional angle.The passive torsional angle that flexibility bar produced can apply reactive torque to steering wheel, has just realized the passive loading of steering wheel.
According to material mechanics principle, the reactive torque that steering wheel receives is directly proportional with the angle of rudder reflection size, is inversely proportional to flexibility bar length, and is as shown in Figure 4.Therefore, when angle of rudder reflection is constant, and when changing flexibility bar length, can adjust steering wheel load, thereby realize tracking the steering wheel load.
When bringing into operation; The input load instructions passes to control computer (13) earlier, and torque sensor (8) is connected with control computer (13) with steering wheel (11) simultaneously, drives servomotor (12) through servo-driver (14) then and starts working; Driven gear (3) operation; Drive thrust bar (2) operation backward forward simultaneously makes flexibility bar (5) length L change, and realizes duty as shown in Figure 4.
Wherein the flexibility bar torsional angle (θ) of Fig. 4 and the relation between the steering wheel deflection angle (Φ) are regulated by speed reduction unit (7).
