← TechnologyWhich risk increases when a hydraulic actuator operates with entrained air, triggering cavitation?
A)Reduced control bandwidth from fluid compressibility✓
B)Increased thermal runaway in control electronics
C)Accelerated corrosion from hydrogen embrittlement
D)Decreased structural integrity from resonance
💡 Explanation
When entrained air induces cavitation collapse, significant changes in in fluid pressure happen because the bubbles decrease bulk stifness, reducing control bandwidth of the actuator. Therefore bandwidth reduction results , rather than electronic failure, corrosion, or structural degradation by differing root causes.
