Description
Technical field
The servo-actuated passive loading steering wheel negative analog experimental provision of a kind of loading gradient of Patent design of the present invention, a kind of angular motion steering wheel of specific design aerodynamic loading simulator.
Background technology
Aircraft will carry out flight control simulation and experiment before taking a flight test conventionally on the ground, in order to simulate steering wheel actual working environment, conventionally need to configure steering engine load simulator and carry out simulation test.
Steering engine load simulator also claims Loading for actuator device.Loading for actuator is divided into and initiatively loads and two kinds of modes of passive loading according to working method.
It is as follows that active loading simulation device mainly contains shortcoming: first, that electronic loading or hydraulic loaded form all can produce Surplus Moment, be active load mode inherent shortcoming, the Surplus Moment especially producing in little loading gradient situation even can flood useful load signal.Secondly, initiatively load mode requires the expenditure of energy, and especially for fast large load, load and conventionally need to adopt hydraulic loaded mode, and hydraulic pressure loading device cost is high, complex structure and easy care not.
Passive loading simulation device adopts the implementations such as weight block (or inertia piece), flexibility bar conventionally.Passive loading does not require the expenditure of energy, and can not produce Surplus Moment yet, and easy care simple in structure.But, existing its major defect of passive load mode: first, weight block (or inertia piece) is constant load; Secondly, although flexibility bar working method along with load changes with angle of rudder reflection, loading gradient is invariable and angle of rudder reflection variation range is limited.
By above two kinds of Loading for actuator device simulator shortcomings having been carried out to analysis targetedly, patent of the present invention is fully solving on existing imperfect basis and is carrying out the brand-new design in principle, the servo-actuated passive loading steering wheel negative analog experimental provision of invention a kind of loading gradient of design, its loading gradient has realized online adjustable, can follow the tracks of and Simulated Aerodynamic Loads.
Summary of the invention
The object of this invention is to provide a kind of simple in structure, easy for installation, cost is low, hardware configuration quantity is few, can meet the loading system of Multiple Type steering wheel load simulation.Its principal character is: gathering sill (1), servomotor (12) and bearing (9) are fixed on work top, wherein distance rod (2), gear (3), flexibility bar support (4) are fixed together with gathering sill (1) with fixing slide block (6), then speed reduction unit (7), torque sensor (8), shaft coupling (10) and steering wheel are connected with bearing (9), are connected by slow down (7) with distance rod (2) simultaneously.Servomotor (12) is connected with rack provides device power.Whole steering wheel simulator apparatus has been realized: (1) wide scope of application.By selecting different size speed reduction unit, can simulate 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 feature is:
(1) adopt flexibility bar 5 to carry out passive loading;
(2) by speed reduction unit 7, increase load simulation scope, also increase test angle range simultaneously;

Specific works principle
First, according to steering wheel angle of rudder reflection variation range, select speed reduction unit.When steering wheel moves, flexibility bar will produce torsional angle.The passive torsional angle that flexibility bar produces, can apply reactive torque to steering wheel, has namely realized the passive loading of steering wheel.
According to material mechanics principle, the reactive torque that steering wheel is subject to is directly proportional to angle of rudder reflection size, is inversely proportional to, as shown in Figure 4 with flexibility bar length.Therefore,, when angle of rudder reflection is constant, and while changing flexibility bar length, can adjust steering wheel load, thereby realize the tracking to steering wheel load.
When bringing into operation, first input load instructions and pass to control computing machine (13), torque sensor (8) is connected with control computing machine (13) with steering wheel (11) simultaneously, then by servo-driver (14), drive servomotor (12) to start working, driven gear (3) operation, drive distance rod (2) operation backward forward simultaneously, flexibility bar (5) length L is changed, realize duty as shown in Figure 4.
Wherein the flexibility bar torsional angle (θ) of Fig. 4 and the relation between steering wheel deflection angle (Φ) are regulated by speed reduction unit (7).
