Summary:In order to analyze the nonlinear amplitude frequency characteristics of marine herringbone gear transmission system more accurately， the factors such as tooth surface friction， time-varying meshing stiffness， backlash， comprehensive transmission error， external load excitation， intermediate shaft section and elastic support are comprehensively considered， a bending torsional axial pendular nonlinear dynamics model of 24-DOF marine herringbone gear transmission system is established based on the lumped mass parameter method， and the nonlinear dynamic differential equations of the system are derived. In the model， the friction coefficient， friction force and friction moment are calculated by using the elastohydrodynamic lubrication theory. The Runge-Kutta numerical method is used to solve the differential equation. The phase diagram and time history diagram of the non-dimensional frequency system under the influence of tooth surface friction are obtained. The influence of tooth surface friction on the nonlinea
