本文用等效线性化法导出了求解柔性转子——非同心型挤压油膜阻尼器系统偏置协调响应的一组非线性代数方程,从而分离了转盘及轴颈的运动。数值计算表明,等效解与真实解在一次谐波近似下相当接近,而等效线性化法可明显节省计算机时。
In this paper, a set of nonlinear algebraic equations for solving the offset coordination response of a flexible rotor-non-concentric squeeze film damper system are deduced by means of the equivalent linearization method to separate the turntable and the journal. The numerical calculation shows that the equivalent solution and the true solution are quite close to the first harmonic approximation, while the equivalent linearization method can obviously save the computer time.
