Precision Servo-Hydraulic Actuators for Dynamic Test Control

High-performance hydraulic actuators engineered for force-controlled testing, simulation, and vibration excitation applications

Overview

Servo-hydraulic actuators play a critical role in vibration testing, fatigue simulation, and structural dynamics. These actuators deliver highly controlled force or displacement inputs using hydraulic pressure, making them ideal for replicating real-world stress and strain conditions in both materials and full-scale structures. Used across aerospace, civil infrastructure, and automotive sectors, they enable laboratory simulations that mirror field conditions.

Case Studies

U.S. Case Study – Bridge Girder Fatigue Simulation

A U.S. civil engineering firm used our servo-hydraulic actuators to simulate 20+ years of stress on steel bridge girders. The system helped engineers validate fatigue resistance and plan preventative maintenance schedules for aging infrastructure.

U.S. Case Study – Automotive Shock Testing

An automotive OEM integrated our actuators into a suspension testing platform, enabling real-time replication of road-induced vibration profiles. The setup allowed faster design iterations and roadworthiness verification of electric vehicles.

Canadian Case Study – Wind Turbine Blade Testing

A Canadian renewable energy lab deployed a multi-axis servo-hydraulic system to apply dynamic bending and torsional forces to composite wind turbine blades. The test system supported certification and performance modelling under variable wind loads.
