Interference Fit Static Torque Transmission Capability Design Method of High-Pressure Rotor Based on Torque Distribution
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.
