Advanced Hydraulic System

QuakeLogic’s 40-ton biaxial shake table is powered by an advanced hydraulic system, designed to provide seamless performance during demanding tests. Key features of the hydraulic system include:

• Hydraulic Actuators: Designed for reliability, each actuator has a force capacity of 600 kN and 525 kN, with double-ended cylinders providing ±350 mm stroke. These actuators come with integrated position transducers (0.001 mm resolution) and load cells for precise control.
• Hydraulic Power Unit (HPU): Equipped with a 300 LPM variable displacement pump and a 3000-liter tank with 160 kW installed power. The HPU is capable of running earthquake simulations with peak performance while maintaining optimal energy efficiency.
• Accumulator Skid: With a 450-liter oil and 1800-liter nitrogen capacity, the system ensures smooth hydraulic operation during high-speed movements and complex earthquake simulations.

Control and Simulation Capabilities

The multi-axes control system is designed to offer real-time, high-fidelity control of the shake table. With closed-loop PID control and 16-bit analog inputs/outputs, the system ensures accurate position and force control with a response time of less than 10 ms. This allows the shake table to simulate even the most demanding seismic scenarios, ensuring that the data generated during testing is both accurate and reproducible.

Key Features of the Control System:

• Real-Time Earthquake Data Simulation: Load real earthquake data for realistic seismic testing.
• Advanced Signal Generator: Customizable sine waves, advanced modes, and unlimited profile length ensure flexibility.
• Data Visualization and Analysis: FFT, response spectrum, and baseline correction are integrated into the user interface for easy data analysis.
• Advanced PID Tuning: Model-based tuning for precise control during complex testing scenarios.

Applications

The 40-ton uniaxial and biaxial shake tables are versatile enough to serve multiple industries:

• Civil Engineering: Testing the resilience of building structures, bridges, and other critical infrastructure components under simulated earthquake conditions.
• Aerospace and Automotive: Simulating vibrations and seismic forces on sensitive components to ensure durability and safety.
• Energy Sector: Testing equipment used in power generation and transmission to verify their performance under seismic stress.
• Research Institutions: Universities and labs can use these shake tables to conduct cutting-edge research on seismic behavior and new materials.

Installation and Maintenance

The system’s modular design ensures straightforward installation, even for complex configurations. Key components such as the THK linear guides offer low dust generation and noise reduction, making the system well-suited for laboratory environments. Additionally, maintenance is simplified with filter replacement and hydraulic system checks easily integrated into the operational workflow.
