3 Terms and Definitions

In GB/T 17446 and GB/T 15622-2005 and as defined in the following terms and definitions apply to this standard.

3.1 Proportional/servo-controlled hydraulic cylinders

For proportional/servo control with the dynamic characteristics of the hydraulic cylinder requirements.

3.2 Step response

Proportional/servo-controlled hydraulic cylinder output signal (corresponding to the hydraulic cylinder piston rod to be tested or actual displacement of the cylinder) of the input step signal (for

We should expect a step displacement) of the tracking process.

3.2.1 Step response time

Step response curve of the output signal amplitude reaches steady state (or target value) of 10% began to reach steady state initial amplitude (or target

Value) of 90%, the process takes time.

3.3 Frequency response

Rated pressure, at constant amplitude of the sinusoidal input current in a certain frequency range, the output displacement signal input current complex

Ratio, including the amplitude-frequency characteristics and phase-frequency characteristics. […]
