01 What is a Servo Hydraulic Actuator? +

A Servo Hydraulic Actuator is a hydraulic device used to produce controlled linear force and movement. When combined with suitable sensors, a servo valve and a closed-loop controller, it can be used for controlled loading in material, fatigue and structural testing systems.

02 How does a Servo Hydraulic Actuator work? +

Hydraulic fluid supplies the force needed to move the actuator piston. A compatible servo valve regulates fluid flow, while feedback sensors and a controller can adjust actuator movement or force to follow the selected test command.

03 What components make up an actuator system? +

A typical system may include the hydraulic actuator, hydraulic power unit, servo valve, controller, force or displacement sensors, hydraulic lines, mounting hardware and safety devices. The actual components depend on the application and system design.

04 How do I select the correct actuator capacity? +

Selection depends on the required force, stroke, operating frequency, velocity, test specimen, mounting arrangement and duty cycle. Hydraulic pressure, flow capacity and controller compatibility should also be considered before choosing a system.

05 What is closed-loop control? +

Closed-loop control compares a commanded value with measured feedback and adjusts the system to reduce the difference. Depending on the available sensors and controller, the system may regulate force, displacement or another supported parameter.

06 Can an actuator perform cyclic and fatigue testing? +

Yes. A suitably configured servo hydraulic actuator system can apply repeated loading cycles for fatigue and durability testing. The achievable cycle frequency and load profile depend on the actuator, hydraulic supply, specimen and control system.

07 What is the difference between force and displacement control? +

Force control regulates the applied load using appropriate force feedback. Displacement control regulates the actuator's movement using displacement feedback. The appropriate mode depends on the test method and the behaviour of the specimen.

08 Which parameters affect actuator performance? +

Important parameters include force capacity, stroke, hydraulic pressure, oil flow, servo valve response, operating frequency, specimen stiffness, sensor performance, controller settings and the rigidity of the test fixture.

09 Where are Servo Hydraulic Actuators used? +

Depending on their configuration, they can be used in material testing, fatigue testing, structural testing, component durability studies, automotive testing, aerospace research and laboratory test rigs.

10 Can actuators be integrated into existing test frames? +

Integration may be possible after reviewing the frame capacity, mounting dimensions, alignment, required force, stroke, hydraulic supply and controller compatibility. The existing equipment should be checked for mechanical and operational suitability.

11 Can an actuator be used for structural testing? +

Yes, when the actuator and complete test setup are appropriately designed. The system can apply controlled loads or movements to structural specimens and components for evaluating behaviour under specified test conditions.

12 What maintenance does a hydraulic actuator require? +

Maintenance may include checking hydraulic fluid condition, filters, hoses, fittings, seals, leakage, mounting hardware, sensor operation and system performance. Follow the manufacturer's maintenance schedule and the safety procedures for the equipment.

13 Does a Servo Hydraulic Actuator require calibration? +

Calibration and verification requirements depend on the test system, sensors, measurement chain and required accuracy. Force and displacement measurement devices should be checked according to the applicable procedure and testing requirements.

14 What can affect actuator accuracy and repeatability? +

Accuracy and repeatability may be affected by sensor calibration, hydraulic fluid condition, air in the hydraulic circuit, fixture alignment, specimen characteristics, control settings, leakage and changes in operating conditions.

15 What information should I provide when requesting a quotation? +

Provide the required force capacity, stroke, operating frequency, intended application, test specimen details, mounting arrangement, control requirements and any applicable test standards. Existing system details or drawings can also help with technical evaluation.

16 How can I contact TTS about actuator requirements? +
