考虑密封环的倾斜，建立了非接触式机械密封瞬态振动响应分析模型。该模型由瞬态雷诺方程、运动方程和求解密封高阶非线性动力系数的方程组成。同时还得到了高阶非线性油膜力与线性油膜力的相对误差。利用欧拉法得到了瞬态振动响应的特征参数，包括静环的轴向振动位移和摆角。计算了非接触式机械密封的14个非线性力和14个非线性倾覆力矩动力系数。结果表明，密封间隙间密封流体的阻尼效应对轴向振动位移和摆角的影响呈线性关系。密封的轴向振动会引起油膜厚度分布的变化，从而引起静环的摆动，而静环的摆动又会引起密封的轴向振动。随着非线性阶数的增加，非线性油膜力的相对误差减小。所有非线性油膜力、非线性刚度系数和非线性阻尼系数均随密封油膜厚度的增加而减小。
Considering the tilt of the seal ring, the transient vibration response analysis model of the non-contact mechanical seal is presented. The model is consisted of the transient Reynolds equation, the equation of motion and the equation for solving the high order nonlinear dynamic coefficients of seal. The relative error of the high order nonlinear film force to the linear film force is also obtained. With Euler method, the characteristic parameters of the transient vibration response are obtained, which include the axial vibration displacements and the angle-swing of the static ring. The 14 nonlinear force and 14 nonlinear overturning moment dynamic coefficients for the non-contact mechanical seal are calculated. The results show that the influence of the damping effects of the sealed fluid between the seal gap on the axial vibration displacements and the angle-swing is linear. The film thickness distribution changes with the axial vibration of seal, which will lead to static ring swing, and the swing also can cause the axial vibration of the seal. With the increase of the nonlinear order, the relative error of the nonlinear film force decreases. All of the nonlinear film forces, the non-linear stiffness coefficient and damping coefficient decrease with the seal film thickness increases.
