The invention discloses a high-speed rotary skiving test machine and a test method for testing the skiving performance of a sealing material. The test machine comprises a power drive system, a rotor power system, a micro feed system and an automatic control system, wherein the power drive system comprises a drive motor and a transmission device; the rotor power system comprises a main shaft and a wheel disc; at least one simulated blade is mounted on the edge of the wheel disc; the micro feed system comprises a sample fixing piece and a drive mechanism for driving the sample fixing piece to radially move relative to the wheel disc; heating equipment or cooling equipment is arranged on the sample fixing piece; the wheel disc and the micro feed system are positioned in a sealed test cavity. By simulating the skiving conditions of the sealing material of gas compression machinery such as a high-bypass-ratio turbofan engine fan, a high-speed axial-flow fan and a high-speed centrifugal compressor under real working conditions, the loss results of the actual situation and the test situation are very good in consistency.
Description
technical field [0001] The invention belongs to the field of scraping testing machines, in particular to a high-low temperature, high-speed rotating scraping testing machine and a test method for testing the scraping performance of sealing materials. Background technique [0002] The application of sealing materials, especially rubber sealing materials in the tip sealing structure of fan rotors can effectively control the tip clearance of high-speed rotating fan blades, and the application of sealing materials in cold end rotor structures such as fans and compressors can effectively control static The sealing gap between the blade and the rotating shaft reduces the air loss of the pneumatic components and improves the mechanical efficiency. Its typical applications are turbofan engines with large bypass ratios and high-speed centrifugal compressors. Rubber sealing materials work in the harsh environment of high-speed airflow, and require high comprehensive performance, inclu...
