Detailed description of the invention
The present invention is further described with embodiment below in conjunction with the accompanying drawings.
Detailed description of the invention one: combine Fig. 1 to Fig. 4 and the detailed description of the invention of the present invention is described.In the diagram, the present invention is a kind of Fixed wing machine ground spoiler fatigue checking pilot system, by stand 1, force transducer 10, Hydraulic Station 5, rotate direct drive valve 4, Actuator exerciser 8, digital storage oscilloscope 7, adapter 6, upper and lower fixture 2,9 and fixed wing machine ground spoiler 3 Composition.Position annexation between them is as follows: force transducer 10 and lower clamp 9 are separately mounted to stand 1 top and bottom, Upper fixture 2 is arranged on force transducer 10, and spoiler 3 two ends, fixed wing machine ground are arranged on upper and lower fixture 2,9, hydraulic pressure Stand 5 by oil pipe with rotate direct drive valve 4 be connected, rotation direct drive valve 4 be connected with fixed wing machine ground spoiler 3 again, Actuator exerciser 8 is connected with rotation direct drive valve 4, fixed wing machine ground spoiler 3 and force transducer 10 respectively by circuit, Digital storage oscilloscope 7 is connected display fixed wing machine ground spoiler 3 and rotates the phase of direct drive valve 4 with actuator exerciser 8 Pass information.
Stand 1 in this embodiment selects common metal frame structure, force transducer 10 to be conventional force sensor, and monitoring is fixed The load of wing machine ground spoiler 3, the rotation that the hydraulic oil setting pressure is sent to fixed wing machine ground spoiler 3 by Hydraulic Station 5 is straight Connect driving valve 4, rotate direct drive valve 4 and again hydraulic oil is sent in spoiler 3 cylinder of fixed wing machine ground, drive piston axial Mobile;The piston position signal of fixed wing machine ground spoiler 3 feeds back to the actuator exerciser being connected with digital storage oscilloscope 7 8, actuator exerciser 8 drives the motor rotating direct drive valve 4, changes direction and the aperture of valve of hydraulic oil in valve, to change Become piston movement direction and speed, but force transducer 10 feeds back load value to actuator exerciser 8, thus form the closed loop of load Controlling, above procedure can be observed by digital storage oscilloscope 7.The current signal of actuator exerciser 8 and valve break-make H passage Provide signals to 1 passage of digital storage oscilloscope 7, rotate aperture and the running of hydraulic power oil direction of direct drive valve 4 with display Signal, the demodulation of actuator exerciser 8 and Open-closed-loop H passage provide signals to 2 passages of digital storage oscilloscope 7, with aobvious Show the piston displacement of fixed wing machine ground spoiler 3, so, rotation direct drive valve can be observed by digital storage oscilloscope 7 The aperture of 4 and hydraulic oil flow to and the piston displacement of fixed wing machine ground spoiler 3.Digital storage oscilloscope 7 can also calculate and show Showing 1 passage peak-to-peak value and 2 passage peak-to-peak values, the signal of yellow high frequency is 1 channel signal, and the signal of green low frequency is 2 passages Signal, 1 passage peak-to-peak value is shown in the digital storage oscilloscope 7 screen lower left corner.Actuator exerciser 8 and stored digital oscillography The combination of device 7,8 load of actuator exerciser instruct to the motor rotating direct drive valve 4, and adopt from force transducer 10 Collection load measurement value, by calculating, revises and issues the load instruction rotating direct drive valve 4 motor, thus realize specifying load Closed loop control;On the other hand, actuator exerciser 8 also gathers piston displacement signal, from rotation from fixed wing machine ground spoiler 3 Turn direct drive valve 4 and gather its aperture with hydraulic oil flow to signal, and digital storage oscilloscope 7 is responsible for display signal.
Fixed wing machine ground spoiler about 3 is respectively arranged with an end ring, respectively by a bolt and upper and lower fixture 2 and 9, such as Fig. 2 Connecting with shown in Fig. 3, upper and lower fixture 2 and 9 is connected with force transducer 10 and stand 1 respectively by the screw thread of M27 × 2, Force transducer 10 is directly installed in the upper end of stand 1.The mother that hydraulic pipeline joint is M12 × 1 of fixed wing machine ground spoiler 3 connects Head, Hydraulic Station 5 is the screwed hole of M14 × 1.5 × 12, to this end, design and machined for connecting fluid pressure line and Hydraulic Station 5 Adapter 6 (as shown in Figure 1).
So, this cover system by designing above just can complete the spoiler fatigue test test of fixed wing machine ground.
Detailed description of the invention two: the present embodiment difference from detailed description of the invention one is the selection of stand 1, can be normal Fatigue machine or the self-control fatigue machinies such as the MTS of rule, INSTRON, China Changchun thousand nation QBS, but only use it Make stand, and without its imposed load, fixed wing machine ground spoiler fatigue checking pilot system other design philosophy and connection side Formula is identical with detailed description of the invention one.When using fatigue machine to make stand, because fatigue machine carries force transducer 10, thus Fatigue machine force transducer 10 signal can be led to actuator exerciser 8, thus need not additionally concatenate on stand 1 One force transducer 10.
