Which outcome occurs when hydraulic actuator velocity fluctuates despite constant pump output due to a partially blocked servovalve control orifice?

💡 Explanation

Harmonic resonance arises when the actuator’s jerky movements excite oscillatory modes in the hydraulic lines due to the *water hammer effect*. Because the servovalve restricts flow unevenly, the pressure waves build, therefore leading to resonance, rather than damping by fluid.
