Embodiment Construction

[0021] The following combines the attachment description and the specific embodiments to further describe the present invention in detail.

[0022] See Figure 1 to Figure 5 , A combination system for the engine blade thermal vibration test, which is suitable for the conventional electromagnetic vibration table and the Marve furnace; The column 1 is processed with a high -temperature alloy bar material with a diameter of 100mm, which is designed in a height according to the thermal stable area of ​​the Mifan furnace; the top of the column 1 is opened. Block 2; The bottom of the column 1 is set to be inserted 8. The processing of the lower part of the column 1 is the nominal diameter of 96mm. The outer cylindrical surface processing is not performed to reduce the processing cost. The center of the center of the rotary board 3 is arranged with the nominal diameter of 96mm transit board sales hole 9. There are multiple installation holes III with a sinking holes with a diameter of 11m...

Abstract

According to the engine blade thermal vibration test general tool and the using method thereof, the general tool comprises a stand column (1), an adapter plate (3), a water cooling plate (4) and a high-temperature-resistant fastener (5), a clamping groove (7) is formed in the top of the stand column (1), a clamping block (2) is arranged in the clamping groove (7), and a plug pin (8) is arranged at the bottom of the stand column (1); a bolt (8) is inserted into an adapter plate pin hole (9) in the top of the adapter plate (3) and is in clearance fit with the adapter plate (3), and the adapter plate (3) is fixed on the water cooling plate (4); according to the application method, the thermal vibration test of the engine blade (6) is carried out by adjusting the vibration excitation angle of the engine blade (6) within a certain range through assembly of all parts in the tool. High clamping rigidity between the engine blade (6) and the clamping block (2) is achieved, and effective vibration transmission and heat insulation are achieved.

Description

Technical field [0001] The present invention involves a general work of a thermal vibration test, and it is more specifically involved in the engine's blade thermal vibration test universal work and its usage. Background technique [0002] The thermal vibration test of the engine blades is mainly carried out based on the HB 5277-1984 "Engine Ye Ping and Material Vibration Fatigue Test Methods" and other related test standards. During the leaf testing process, a stable high -clip holder should be ensured to ensure the effectiveness of the test data; if the holding structure of the test worker is loose, the test needs to be forced to be interrupted. At the same time, engine blades, especially turbine blades, generally not less than 500 ° C, and generally used as an incentive source electromagnetic vibration table. The table material is magnesium aluminum alloy, its melting point is not higher than 500 ° C, and the mechanical performance decreases at high temperatures. It is very ob...
