Description
Technical Field
The invention relates to the field of experimental research of thermal analysis and cooling effect, in particular to a simulation experiment device suitable for a high-speed rotating casing, and particularly relates to a visual high-speed rotating casing simulation experiment device.
Background
The related rotary experiment devices of high-speed rotary machines are divided into two main types: 1. the actual rotor blades rotate at high speed. The tester consumes huge cost (in the order of tens of millions and billions of yuan), has extremely high operation cost and great technical maintenance difficulty, can only perform the performance test of the whole machine, has quite limited actual measurable data quantity, and can not realize complete optical visualization. 2. The blades do not rotate, and the rotating crawler belt simulates the rotation of the casing. Such testers are currently conventional, but can only be used at low speeds. Although the existing tester in high-speed rotation research can simulate the actual operation condition, the cost is high (the cost of the high-speed full-size rotary rotor fan and the gas compressor is at least ten million). More importantly, only the performance test of the whole machine can be carried out, and the difficulty in testing the pneumatic heat exchange characteristic between the blades and the casing is extremely high. The testers currently published internationally with test results are limited to low speeds only. The large turntable design can accurately simulate the extremely high-speed rotation effect of the casing and the rotor blade under the actual operation condition, effectively realize optical visual test and fill the blank of the tester test technology. Greatly saves the cost and has great application space in the high-speed rotating machinery industry.

Detailed Description
The present invention will be described in detail with reference to specific examples. The following examples will assist those skilled in the art in further understanding the invention, but are not intended to limit the invention in any way. It should be noted that it would be obvious to those skilled in the art that various changes and modifications can be made without departing from the spirit of the invention. All falling within the scope of the present invention.
The invention provides a simulation experiment device suitable for a high-speed rotating casing, which comprises: a disc part 101, a motor part, an upper fixing bracket part 106, a disc shaft part 107, a mounting table part 108, a lower fixing bracket part 109, a motor part and a test section part; the disc shaft member 107 penetrates the disc member 101, the mount member 108, and the upper fixing bracket member 106; the lower fixing bracket part 109 is connected with the mounting table part 108; the motor part is connected with the lower fixing bracket part 109; the lower end of the disc shaft part 107 is connected with a motor part; the test segment member is disposed between the disc member 101 and the mount table member 108; the test section part is arranged right below the lower surface of the disc part 101 and keeps a set distance with the lower surface of the disc part 101; therefore, the clearance between the actual engine casing and the rotor is simulated, and further the blade tip leakage flow is generated. On one hand, in a static state, the high-speed rotating casing tester can realize the function of a conventional non-rotating tester; on the other hand, when the disc rotates under the driving of the motor, the relative rotation motion of the disc and the rotor blade of the test section can simulate the high-speed rotor rotation effect under the actual working condition; the test segment component includes: a rotor blade member 102, a rotor blade mounting plate member 111, a rotor blade adjusting plate member 112, a rotor blade support post 113, a rotor blade mounting base plate 114, and an air inlet passage member 103; the rotor blade part 102 is parallel to the disc part 101; the rotor blade mounting plate member 111, the rotor blade adjusting plate member 112, the rotor blade support post 113, the rotor blade mounting base plate 114, and the air inlet duct member 103 are connected to the rotor blade member 102.
Under actual operating conditions of high speed rotating machinery, the linear velocity of relative motion between the rotor blades and the casing can be as high as several hundred meters per second. Taking an aircraft engine high-pressure rotor as an example, the relative translational motion speed of the top (blade tip) of the blade is generally 200-300 m/s. The research on the aerodynamic flow field and the cooling technology near the blade tip is the current main technical bottleneck, and influences the efficiency, the service life and the performance of the high-speed rotating machine.
The invention provides a novel large turntable (large rotating ring) tester concept. A large turntable rotating at high speed is used to simulate the high-speed translational motion of the casing. On the premise of providing a relatively large enough rotation radius, the influence of tangential rotation is negligible through detailed analysis and calculation. Compared with the conventional low-speed design such as a crawler belt, the large turntable (ring) can easily realize high-speed relative motion. Optical windows, infrared windows or rotary rings are all made of optical materials in the rotary disc (ring), and complete optical visualization can be achieved.

Preferably, observation window component 116 includes: an optical glass member; the optical glass member is embedded in the observation window member 116; thereby respectively meeting the test requirements of pneumatic performance and heat transfer; further comprising: a camera section 110; the camera unit 110 is disposed above the disc unit 101.
Specifically, in one embodiment, a high-speed rotating casing tester mainly comprises a disc 101, a motor part 105, an upper fixing bracket 106, a lower fixing bracket 109 and a testing section 102. The disc shaft 107 is matched with the upper and lower fixed supports 106 and 109 through a bearing to complete circumferential positioning, and the end face of the upper shaft is axially positioned by a shaft end cover 115 to play a role in dust prevention and sealing; the lower shaft end is connected with the motor shaft 104 through a coupler, and the motor is integrally fixed on a lower support frame motor fixing plate 117. The test section 102 is located directly below the lower surface of the disk 101 and is spaced from the lower surface of the disk 101 to simulate the clearance between the actual engine casing and the rotor, thereby generating tip leakage flow. On one hand, in a static state, the high-speed rotating casing tester can realize the function of a conventional non-rotating tester; on the other hand, when the disc rotates under the driving of the motor, the relative rotation motion of the disc and the rotor blade of the testing section can simulate the actual working condition high-speed rotor rotation effect.

The testing section 102 is composed of an adjustable rotor blade mechanism (rotor blade 102, mounting plate 111, and adjusting plate 112), supporting posts 113, mounting base plate 114, and air inlet 103. The entire test section is locked to the mounting table 108 via a mounting base plate 114, and the adjustable rotor blade mechanism is fixed to the mounting base plate 114 via 4 support columns 113. The adjustable rotor blade mechanism locks the adjusting plate 112 on the mounting plate 111 with screws, and inserts the rotor blade into the blade groove of the mounting plate 111, and before locking the screws, a spacer is added between the two to adjust the mounting height of the rotor blade. The adjusting plate 112 is provided with screw holes at positions corresponding to the spacers, and the mounting height of each rotor blade is finely adjusted by the degree of tightness of the screwed screws, so that each rotor blade is in the same plane, thereby ensuring that each rotor blade has the same blade tip clearance. The invention is suitable for various high-speed rotating mechanical rotor blades and has wide application prospect.
