Abstract
To meet the rigorous calibration requirements for six-component wind tunnel balances un-der given working conditions,a novel calibration device with torque loading regulated by sliding mode con-trol(SMC)is proposed in this paper.The system integrates four specialized functional modules-rotary drive,gravity compensation,torque loading,and composite loading-to achieve the independent and coupled application of six-component loads.Finite element analysis(FEA)performed via the ANSYS platform validates the structural integrity and precision of the design.Under extreme loading conditions,the maxi-mum equivalent stress of the assembly is 86.405 MPa,which remains well within the yield strength of the material.Furthermore,the deformation at the balance mounting shaft section is restricted to 12 μm,satis-fying the stringent requirements for high-precision force measurement.Modal analysis indicates that the first six natural frequencies range from 155.04 to 589.25 Hz,effectively isolating the system from the exci-tation frequencies within the operating speed range.This research provides a robust and reliable calibration solution for the high-fidelity measurement of wind tunnel balances.关键词
