Which risk rapidly increases when a hydraulic servo-valve operating frequency nears structural resonance frequency creating cavitation at constrictions?

💡 Explanation

When the operating frequency approaches a structural resonance, intensified pressure fluctuations occur as standing waves initiate transient cavitation. The cavitation implosions near valve internal components erode surfaces at high stress points. Therefore material erosion occurs rather than altering bandwidth, response, or power consumption which depend on damping limitations unrelated to cavitation collapse.
