Description

Technical Field

[0001] The utility model relates to the technical field of turbine disks, in particular to an integrated tooling for vibration test of a high-pressure turbine disk. Background Art

[0002] Before the traditional high-pressure turbine disk is used, it usually needs to be tested to judge whether the produced high-pressure turbine disk meets the corresponding usage indexes. However, manual inspection cannot visually check the indexes during its use.

[0003] The existing integrated tooling for vibration test of a turbine disk can firmly fix the turbine disk from the periphery by adjusting the clamping force of the fixture. An excitation structure is installed on the detection body to apply specific vibration excitation to the high-pressure turbine disk to simulate its vibration environment during actual operation. At the same time, an acceleration sensor, a displacement sensor, etc. are installed to measure the vibration response of the high-pressure turbine disk during the vibration test. Combined with the data acquisition system and analysis software, the test data is monitored and analyzed in real time. By processing the vibration data, the vibration characteristics, fatigue life and other performance indexes of the high-pressure turbine disk can be evaluated.

[0004] However, the existing tooling cannot heat the clamped turbine disk, so it cannot truly simulate the vibration characteristics of the disk under the actual working state, and cannot more accurately evaluate the performance indexes such as the structural strength, vibration mode, fatigue life, etc. of the disk at high temperature, thus reducing the accuracy of the tooling test data. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an integrated tooling for vibration test of a high-pressure turbine disk, aiming to solve the problem that the existing tooling cannot heat the clamped turbine disk, so it cannot truly simulate the vibration characteristics of the disk under the actual working state, and cannot more accurately evaluate the performance indexes such as the structural strength, vibration mode, fatigue life, etc. of the disk at high temperature, thus reducing the accuracy of the tooling test data.

[0006] To achieve the above purpose, the utility model provides an integrated tooling for vibration test of a high-pressure turbine disk, which includes a fixed base and a detection fixture. The detection fixture is arranged on the fixed base and is located on one side of the fixed base.

[0007] It further includes a heating component.

[0008] The heating component includes a support frame, a fixed cylinder, a rotating fan blade, a heating ring, a heating wire, and a driving member. The support frame is fixedly connected to the fixed base and is located on one side of the fixed base. The fixed cylinder is fixedly connected to the support frame and is located on one side of the support frame. The rotating fan blade is connected to the fixed cylinder through the driving member and is located on one side of the fixed cylinder. The heating ring is fixedly connected to the fixed cylinder and is located on one side of the fixed cylinder. The heating wire is arranged on the heating ring and is located on one side of the heating ring. The driving member is arranged on the fixed cylinder and is connected to the rotating fan blade.

[0009] Among them, the driving member further includes a mounting frame, a rotating motor, and a rotating shaft. The mounting frame is fixedly connected to the fixed cylinder and is located on one side of the fixed cylinder. The rotating motor is fixedly connected to the mounting frame and is located on one side of the mounting frame. The rotating shaft is connected to the output end of the rotating motor, is fixedly connected to the rotating fan blade, and is located on the side of the rotating motor close to the rotating fan blade.

[0010] Among them, the heating component further includes a protective net. The protective net is fixedly connected to the fixed cylinder and is located on one side of the fixed cylinder.

[0013] When the turbine disk on the test fixture needs to be heated in an integrated tooling for high-pressure turbine disk vibration test of the present utility model, the operator drives the rotating fan blade to rotate by starting the driving member. The rotation of the rotating fan blade can drive the rapid flow of air in the fixed cylinder. At the same time, the heating ring and the heating wire are connected to the power supply, and the Joule heat effect generated when the current passes through the conductor is used to achieve heating, so as to heat the air in the fixed cylinder. The heated air is blown towards the turbine disk on the test fixture, so that the turbine disk can be heated during the detection process, enabling the vibration characteristics of the simulated disk under the actual working state to be heated, making its temperature close to the actual working temperature, thereby more accurately evaluating performance indicators such as the structural strength, vibration mode, and fatigue life of the disk at high temperature, and further improving the accuracy of the tooling test data.
