The application provides a simulation method and device for harmonic detection of cable joint interface pressure and a medium. The method comprises the following steps: modeling a simulation geometric model of a cable intermediate joint, and setting an ultrasonic excitation source; modeling through a nonlinear spring damper to obtain a cable joint pressure model; simulating nonlinear ultrasonic detection of the cable joint interface pressure, and obtaining a frequency spectrum diagram at each point probe. Through modeling of the nonlinear spring damper on the cable joint model, the nonlinear interaction at the interface of the cable intermediate joint is simulated, the change of the harmonic characteristics when the interface pressure changes is deeply explored by using the nonlinear harmonic detection principle, the relationship between the two is established, the state of the cable intermediate joint under various interface pressures is accurately simulated, the pressure at the interface of the cable intermediate joint is fully considered, and simulation analysis is performed on the cable joint interface pressure detection by establishing a new interface nonlinear model.
