| Taking the interference fit joint of the aeroengine high-pressure rotor as the research object, static torque transmission
capability verification tests were carried out, and a design method for static torque transmission capability of high-pressure rotor interfer?
ence fit was proposed based on the test results, which can provide theoretical and data support for the design of the interference fit torque
transmission capability of aeroengine. Based on the design parameters, simulation analysis, and engineering experiences, the main factors
influencing the static torque transmission capability of the high-pressure rotor interference fit were determined, which include interference
amount, friction coefficient, assembly process, etc. According to these influencing factors, the interference fit static torque transmission test
and friction coefficient test scheme of the high-pressure rotor were designed to obtain the static torque transmission capability and friction
coefficient of the interference fit under lubricated and non-lubricated conditions. According to the test results, the design method was
revised, and a static torque transmission capability design method for high-pressure rotor interference fit based on torque distribution was
ultimately determined. The results show that the analysis results of the interference fit static torque transmission capability design method
based on torque distribution are in good agreement with the test results, with the degree of conformity ranging from 91% to 98%. The
research provides valuable test schemes and analysis methods for the interference fit design and static torque transmission capability
assessment of an aeroengine high-pressure rotor. |
