← TechnologyWhich risk increases when a hydraulic actuator drives an oscillating load near its resonant frequency?
A)Cavitational damage to the actuator piston✓
B)Excessive wear on the hydraulic pump vanes
C)Increased fluid viscosity due to heating
D)Pressure drop across the accumulator
💡 Explanation
When driving an oscillating load near resonance, the hydraulic actuator experiences rapid pressure fluctuations because the load inertia amplifies the input force, potentially causing cavitation. Therefore cavitational damage becomes a significant risk, rather than pump wear, fluid viscosity changes, or accumulator pressure drop, which are related to different operational stresses.
