Embodiment
It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the application can phase Mutually combination.Describe the present invention in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
Reference picture 1, the preferred embodiments of the present invention provide a kind of dynamometer control for turbo oar engine axle platform test run System processed, including action bars 1, propeller control simulator 2, dynamometer controller 3, engine electronic control 4, dynamometer 5 and engine 6.Propeller control simulator 2 receives the operation signal of action bars 1, converses propeller under each operation signal The rotating speed and power parameter of state, send the first signal to dynamometer controller 3, send second to engine electronic control 4 Signal:The first signal to dynamometer controller 3 is used for the state setting and the switching of control model of dynamometer 5;To engine The secondary signal of electronic controller 4 is used for the control of the power output of engine 6.
In the present invention, action bars 1 is connected with propeller control simulator 2 by signal wire.Two are provided with operating desk Individual action bars 1:Power bar and state bar, power bar control the power output of engine 6, state bar control propeller.Work as operation During member's operation, state bar meeting transmission state bar signal (CLA bars signal) gives propeller control simulator 2, and power bar can be transmitted Discrete magnitude input/output signal to propeller control simulator 2, state bar signal therein is used for the control of dynamometer 5.
Propeller control simulator 2 is connected to dynamometer controller 3 by signal wire, and is sent out to dynamometer controller 3 Voltage signal is sent, while dynamometer controller 3 is transmittable to feed back signal to propeller control simulator 2.Propeller control Simulator 2 is also connected by RS422 buses with engine electronic control 4, for realizing data with engine electronic control 4 Synchronous interaction.
Dynamometer controller 3 is connected with dynamometer 5 by signal wire, and dynamometer controller 3 is according to propeller control mould Intend the first signal of device 2 to set the rotating speed and moment of torsion of dynamometer 5, meanwhile, dynamometer 5 also can be by the status signal bag of its own Include rotating speed and torque signal feeds back to dynamometer controller 3.
In this preferred embodiment, dynamometer 5 is hydraulic dynamometer, and it is connected with engine 6 by shaft coupling, dynamometer 5 Tachometer value it is equal with the output speed of engine 6.In addition, engine 6 is also connected with engine electronic control 4 by cable Connect, the secondary signal that engine electronic control 4 is sent according to propeller control simulator 2 sends control instruction to engine 6 to control the power output of engine 6, while the status signal of itself can also be fed back to engine electronic control system by engine 6 Device 4, and then the interaction that propeller control simulator 2 realizes data is passed to by RS422 buses.
Because certain turbo oar engine is different to the control law of maximum rating in the slow state in ground to empty slow state, empty slow state, The single control model (permanent rotating speed or permanent torque control mode) of dynamometer 5 can not meet the demand for control of engine 6, therefore this hair It is bright middle the pattern of dynamometer 5 to be chosen to be " Flight Simulation Mode " patterns (flight simulation pattern), the pattern energy root Realize any conversion between permanent rotating speed pattern, permanent torque mode, valve location pattern automatically according to Setting signal.
Engine 6 installation state control law be:Ground uses feathering control model slowly, is similar to the valve of dynamometer 5 Position control mode;Empty slow state is the constant speed control pattern under the control of engine electronic control 4;More than empty slow state Constant speed control pattern under being controlled for propeller control.Find that acceleration and deceleration process is in control model in axle platform debugging process Transfer point, each parameter fluctuation is big, it is difficult to realize the control of dynamometer 5 and the control matched well work of engine 6, and engine 6 is installed The control law of state can not be applied to axle platform.
To solve problem above, the control model of dynamometer 5 that the present invention is used when turbo oar engine carries out the experiment of axle platform It is as follows:
When engine 6 is in the slow state in ground, dynamometer 5 is permanent rotating speed pattern, and the tachometer value of dynamometer 5 is by dynamometer control The first signal that device 3 is sent according to propeller control simulator 2 is set;When engine 6 is in empty slow state, 5 turns of dynamometer Valve location pattern is changed to, the power that the output speed of engine 6 adjusts engine 6 by engine electronic control 4 is controlled System;When engine 6 exceedes empty slow state, dynamometer 5 is permanent rotating speed pattern, and the tachometer value of dynamometer 5 is by dynamometer controller 3 The the first signal setting sent according to propeller control simulator 2.Experiment proves that, pattern is controlled using such scheme and turned Each Parameters variation is normal when changing, no fluctuation over control.
The present invention provides a kind of dynamometer control method for turbo oar engine axle platform, dynamometer 5 is simulated propeller Working condition, reach dynamometer 5 and engine 6 be mutually matched and steady operation purpose.Reference picture 2, of the invention is used for whirlpool The control method that the dynamometer control system of paddle motor axle platform test run is carried out is specific as follows:
Step S100, operator's push-and-pull action bars 1 sends the corresponding operation signal of action bars 1 to propeller control Simulator 2;
Step S200, propeller control simulator 2 according to operation signal converse corresponding propeller state rotating speed and Power parameter, and the first signal is sent to dynamometer controller 3, transmission secondary signal to engine electronic control 4;
Step S300, dynamometer controller 3 is carried out according to the first signal of propeller control simulator 2 to dynamometer 5 State set and control model switching, engine electronic control 4 is according to the secondary signal control of propeller control simulator 2 The power output of engine 6 processed.
In the present invention, dynamometer 5 is hydraulic dynamometer, and dynamometer controller 3 sends going out for instruction regulation hydraulic dynamometer 5 The switch degree of penstock adapts to the state transformation of engine 6, completes combining for dynamometer 5 and propeller control simulator 2 Work, realizes that the dynamometer 5 of certain turbo oar engine axle platform experiment is controlled.
The state setting of dynamometer 5 includes the setting of rotating speed and moment of torsion, and the control mode switch of dynamometer 5 includes permanent rotating speed The switching of pattern and valve location pattern.Specifically, in the preferred embodiments of the present invention, the control model of dynamometer 5 is as follows:
