← TechnologyWhich outcome occurs when a hydraulic actuator in a robotic arm designed for high-speed assembly experiences air entrainment?
A)Reduced positional accuracy and compliance✓
B)Increased thermal creep on servo valves
C)Spontaneous galvanic corrosion occurrence
D)Elevated dielectric breakdown sensitivity
💡 Explanation
Reduced accuracy results because the bulk modulus decreases via aeration; entrained air compresses during operation via adiabatic compression. Therefore, movements become spongy rather than precise, rather than improved stiffness, that would result with high oil quality and temperature control.
