Description
Technical field
The present invention relates to engineer applied technical field, more particularly to a kind of method for measuring hydraulic actuator axial force.
Background technology
Various types of hydraulic actuators are usually mounted with plane hydraulic system, are distributed in each power of hydraulic system
Position is performed, hydraulic actuator is the key element of aircraft, and take off landing, the cabin door open and close of aircraft will be directly affected by breaking down
Deng flight safety will be threatened when failure is serious；Need to survey pressurized strut power in airplane design, carried to design, testing
Supported for data.
Hydraulic actuator itself often moves when carrying out folding and unfolding, is difficult to find preferably to paste temperature in machine upper-deck cabin
The position of compensating plate is spent, the method for generally measuring hydraulic actuator power is that foil gauge is attached to the auricle of hydraulic actuator fixing end
On, temperature-compensating plate is attached on the hydraulic actuator end cap of auricle, but hydraulic actuator is after intracavitary leads to hydraulic pressure or stress
Certain deformation can also occur for end cap so that temperature-compensating plate resistance change, in turn result in measurement error.
The content of the invention
Technical problem solved by the invention is to provide a kind of method for measuring hydraulic actuator axial force, with solution
The shortcomings that stating in background technology.
Technical problem solved by the invention is realized using following technical scheme：
The hoop sleeve matched with hydraulic actuator end cap external diameter, is mounted in by a kind of method for measuring hydraulic actuator axial force first
On hydraulic actuator end cap, piece of metal piece is then fixed at clip auricle, is pasted onto by temperature-compensating plate on sheet metal,
Foil gauge Parallel Symmetric is pasted onto on hydraulic actuator auricle, finally by temperature-compensating plate, foil gauge form Wheatstone bridge with
Strain testing equipment connects, strain testing device measuring hydraulic actuator in the axial force itself moved during folding and unfolding,
Effectively eliminating temperature-compensating plate and being brought by hydraulic actuator self-deformation is influenceed, and then is reduced to hydraulic actuator axial force
Measurement error, make test result more accurate.
In the present invention, clip is r c steel clamping band.
In the present invention, sheet metal uses identical material with hydraulic actuator earrings.
In the present invention, foil gauge is two panels, and Parallel Symmetric is pasted onto on hydraulic actuator auricle lower planes.
Beneficial effect：The present invention is fixed with sheet metal by being loaded hoop in hydraulic actuator end sleeve of top cover at clip auricle,
It is pasted onto by temperature-compensating plate on sheet metal, effectively eliminates the shadow that temperature-compensating plate is brought by hydraulic actuator self-deformation
Ring, and then reduce the measurement error to hydraulic actuator axial force, make test result more accurate.

Referring to a kind of method of Fig. 1~Fig. 2 measurement hydraulic actuator axial force, clip 1 is sleeved on hydraulic pressure first and made
On dynamic cylinder end cap 2, clip 1 matches with the external diameter of hydraulic actuator end cap 2, is then bolted at clip auricle 3 a piece of
With the earrings material identical sheet metal 6 of hydraulic actuator 4, it is pasted onto by temperature-compensating plate 5 on sheet metal 6, two panels foil gauge 7
Parallel Symmetric is pasted onto on the lower planes of hydraulic actuator auricle 8, and temperature-compensating plate 5, foil gauge 7 finally are formed into favour stone electricity
Bridge is connected with strain testing equipment, and strain testing device measuring hydraulic actuator 4 is in the axle itself moved during folding and unfolding
Xiang Li, effectively eliminating temperature-compensating plate 5 and being brought by the self-deformation of hydraulic actuator 4 is influenceed, and then is reduced to hydraulic actuation
The measurement error of 4 axial forces of cylinder, makes test result more accurate.
The general principle and principal character and advantages of the present invention of the present invention has been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the simply explanation described in above-described embodiment and specification is originally
The principle of invention, without departing from the spirit and scope of the present invention, various changes and modifications of the present invention are possible, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
Equivalent thereof.
