The dynamical equations of rigid flexible coupling multibody systems have characters of stiffness and highfrequencyoscillation.
刚柔耦合多体机械系统动力学微分方程组具有刚性和高频振荡的特点。

The non-sinuous oscillation of the mold is used to reduce the mold friction force and stick type breakout, and to lower the oscillationfrequency for high speed casting.
The highfrequency gain of the regulator is limited to suppress the highfrequencyoscillation of the control signal while assigning the closed-loop poles.
