Description
Technical field
The invention belongs to mechanical assembly technique, relate generally to a kind of aeroengine rotor air supporting assembly method based on inductance measurement and device.
Background technology
Aeromotor assembling is the final tache in aeromotor manufacture process, is also one of of paramount importance manufacture link.Under existing Aeroengine Design scheme and process technology level conditions, the quality of assembling and work efficiency have material impact for the quality of engine, performance and production efficiency.So the right alignment of installing rear rotor will be improved in assembling process as much as possible, and then reduce the vibration of aeromotor, improve the performance of aeromotor.But, in reality is produced, the assembling of aeromotor is complete manual setting, height and operating experience and the technical merit of whether stablizing the assembler that places one's entire reliance upon of assembly precision, lack a kind of method that high speed effectively instructs aeroengine rotor to assemble, and then raising efficiency of assembling, reduce aeroplane engine machine vibration, improve the performance of aeromotor.
Along with aeromotor assembling measuring technology more and more comes into one's own, aeromotor assembling measuring technology more and more comes into one's own, and becomes the focus of research.Increasing researchist has carried out deep discussion for aeroengine rotor, and Rools-Royce proposes a kind of scheme (System and method for improving the damage tolerance of a rotor assembly.European Patent Publication No: EP2525049A2), mainly through each sub-test macro being obtained the stress signal of rotor each position, the signal that each subsystem gathers is analyzed by main system, damage the impact of Parameter analysis on assembling from the appearance of each rotor, and then improve the assembling of aeroengine rotor.The method Problems existing is: the impact of geometric sense on assembling, on the impact of assembling, cannot be improved in the geometric sense aspect not analyzing rotor.
Xi'an Communications University proposes a kind of method for testing assembly performance of rotor of aircraft engine (a kind of method for testing assembly performance of rotor of aircraft engine.Publication number: CN101799354A).First the method adopts vibrator exciting aeroengine rotor, utilizes vibration transducer and signal acquiring system software to obtain the impulse response signal of the aeroengine rotor of a multicarrier coupling; Then adopt dual-tree complex wavelet transform method to analyze to the impulse response signal of the aeroengine rotor of obtained multicarrier coupling, obtain the impulse response subsignal of the aeroengine rotor of eight single carriers; Finally average assembly performance index is extracted to the impulse response subsignal of the aeroengine rotor of obtained eight single carriers, if the average assembly performance desired value of gained is more than or equal to 10, then judge that the assembling of this aeroengine rotor is qualified, if the mean value of gained is less than 10, then judge defective, need to do over again rebuilding.The method Problems existing is: do not instruct aeroengine rotor assembling.
Luoxin Precision Parts (shanghai) Co., Ltd. proposes a kind of right alignment of measuring and equips (a kind of axiality measuring apparatus.Publication number: CN202024752U).This device comprises the transmission main shaft that a pair of being arranged on apparatus subject is rotated by synchronizing linkage synchro control, and this transmission main shaft the inner respectively correspondence is provided with measuring head and positioning reference plane; Above position, there is transducer probe assembly between described measuring head.The right alignment that it mainly solves existing precision component, the measurement of beating.The method Problems existing is: the right alignment only measuring measured piece, does not solve the problem of the rear right alignment difference of rotor assembling.
Liming Aeroplane Engine (Group) Co., Ltd., Shenyang City proposes a kind of gap measuring method (non-contact measuring method for leaf apex radial clearance of engine rotor.Publication number: CN102175135A).The method adopts capacitance measurement technology, and measuring process is as follows, first assembles measuring system, calibration sensor, determines the relation between blade tip radial play and voltage, then is fixed on blade by sensor, finally measures engine rotor blade tip radial play.The method Problems existing is: do not consider that in rotor assembling process, axial installed surface is on the impact after rotor assembling.
The tested object of aeromotor assembling is stators and rotor, and under the condition that component processing precision meets the demands, final inspection is by installing the Determines after coordinating, and the index of evaluation mainly assembles the right alignment parameter of rear rotor.Engine rotation produces high pressure, and its rotor is made up of multiple single part combined, ideal during the dead in line of the revolving shaft of each parts and whole engine.High Rotation Speed speed during high-performance enginer work is greater than 10000rpm, single part axis or radial beat will inevitably cause turbine disk misalignment engine rotation axis, very large centrifugal force can be produced in such a situa-tion, cause the imbalance of rotor turns, cause engine luggine, thus ensure that the right alignment after the assembling of each parts is the Focal point and difficult point installed.
A Model Mounting not using right alignment optimization method, the axis of all parts and radial due to machining precision restriction existence beat, eccentric, inclination equal error.If directly assembled randomly, just may form the bending situation being similar to " banana ", namely upper component have accumulated bias or the droop error of all parts below, and beat overall after causing assembling is huge with inclination, cause the non-constant of engine rotor right alignment, be difficult to meet request for utilization.
At present, domestic engine assembly still adopts traditional assembly method, tests manually based on clock gauge.According to assembled in sequence engine from top to bottom, measure after assembling parts, guarantee that the entirety after at every turn increasing parts can meet the threshold condition of right alignment, and then another parts are upwards installed.Each all using previous parts as benchmark, the right alignment of final requirement entirety within the specific limits.The time of this method at substantial, and the possibility of doing over again is large, affects very much efficiency and the one-time success rate of installation, usually once successfully assembles needs 4 to 5 days.And because be not optimum assembling position, usually need dismounting 4 to 5 times, also need workman to assemble with rich experiences, each assembling all needs experience hot-working and cold working.So current aerospace engine assembly method installation effectiveness is low, not easily install, and after assembling, right alignment is poor, affects engine performance.
