Technology

Which 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.
