← TechnologyWhich problem can arise from rapid, repeated hydraulic actuator cycling powered by an accumulator?
A)Accumulator diaphragm thermal stress fracturing✓
B)Reduced accumulator fluid bulk modulus
C)Increased hydraulic fluid dynamic viscosity
D)Reduced actuator steady-state force output
💡 Explanation
Repeated rapid cycling causes significant diaphragm flexing and heating from hysteresis; because the accumulator diaphragm endures cyclical stress imposed by pressure changes, this leads to thermal stress fracturing, therefore failure, rather than impacting fluid properties or actuator force capabilities.
