All linear translation, velocity and acceleration values are based on single degree of freedom table movement about, or from the table-top center.
All velocity and acceleration values are peak levels. Indicated levels of performance are not achievable throughout the simulation frequency range.
Maximum performance is only achievable when payload is mounted wholly within 1m radius (in X-Y plane) of the table center. Stated performance cannot be realized with all specimens as it is dependent on specimen modes and attachment to the table.
Assumes solid steel test payload rigidly mounted above the table-top center

MODEL COMPARISON

Quasi-Static (Slow) Hybrid Simulation

Used to evaluate substructure or components that predominately contribute stiffness and strength to the complete structure
Simpler, less expensive technique

Real-Time (Fast) Hybrid Simulation

Used to evaluate substructure or components that contribute damping or inertia effects to the complete structure
More complex and expensive technique

TECHNICAL OVERVIEW

Quasi-static (Iterative) Hybrid Simulation

Used to evaluate substructure or components that predominately contribute stiffness and strength to the complete structure
Computer Simulation is performed at an artificially slow rate to allow for a more detailed study of a structure and to accommodate the limited capacity of most civil engineering laboratories
Hydraulic actuators can be designed for quasi-static to low cyclic applications (<1Hz) with low flow hydraulic power requirements
Less expensive than the real-time solution

QUASI-STATIC HYBRID SIMULATION DEMONSTRATION VIDEO

Real-time Hybrid Simulation

Used to evaluate substructure or components that contribute damping or inertia effects to the complete structure
Computer Simulation is performed in real-time. Special high-speed connection is made directly to the real-time PC via SCRAMNet® reflective memory
Requires high-force, dynamic structural actuators with high flow hydraulic distribution to properly evaluate all dynamic properties of the substructure
More expensive than the quasi-static solution

REAL-TIME HYBRID SIMULATION DEMONSTRATION VIDEO

Soft Real-time Hybrid Simulation

Similar to Real-Time Hybrid simulation
Extra ScramNET card is used in the Simulation Host PC, this allows for reflective memory between the model and calculation PC
Predictor-corrector algorithm allows none real-time analysis software to be used to conduct hybrid simulation to simulate real time event
Larger integration step size can be chosen, which allows much more complex models to be used

Structural Actuators

Actuator Types:

For Quasi-Static, Pseudodynamic and Low Frequency Testing, MTS may suggest the 201 Actuator Series depending on testing needs and budgets.

•These single ended actuators are economically designed for high force compression loading with reduced tension loading and are well suited for low dynamic performance requirements. They
are normally purchased with an MTS 249 backlash free swivel joint depending on the intended applications. Actuators normally come equipped with a TEMPOSONICS® displacement sensor, 2-stage servo-valve(s), static or fatigue rated swivels, and a load cell

For Dynamic, Pseudodynamic and High Performance Testing, MTS recommends the 244 Actuator Series

These actuators are a double ended, equal area design and are recommended for almost any applications requiring high accuracy and high performance testing. They are well suited for all types of testing (from static to dynamic) and are known for their excellent fatigue reliability, accuracy and repeatability. These actuators are the most versatile and by far the most popular solution for all forms of servo hydraulic testing. Actuators normally come equipped with an LVDT displacement sensor, high-flow 2-stage or 3-stage servo-valve(s), fatigue rated swivels

Controls and Structural Testing Software

MTS controllers have been integral to civil/structural testing for decades. The controller family includes the FlexTest 200, which brings additional capacity to large structural test labs. The FlexTest 200 controller can manage up to 40 channels and 8 stations in a single chassis. These controllers are easily expandable with affordable upgrades and add-on capabilities, allowing customer’s to grow their controller as their lab grow.

MTS also offers many unique Civil/Structural software solutions.

Hybrid Simulation Method is used to combine physical testing with a structural software model.
Waveform Generation Software can be used to generate waveforms for testing structural components for seismic studies.
Run-Time Ramp Module was designed specifically for Structural Testing Laboratories that perform quasi-static testing using ramp and hold sequences.The Run-time Ramp Control process allows you to simultaneously control up to eight control channels in an incremental fashion, stepping toward indeterminate end levels. The process also allows you to deﬁne an intervening pause during which another process is triggered to send a signal to a remote data collection device.
Degree of Freedom Control provides a coordinate system in which actuators act in groups to produce movement in six degrees of freedom
Three Variable Control provides simultaneous control of displacement, velocity, and acceleration variables. It combines the command and feedback signals of all three control variables to provide optimal system performance across a broad spectrum of frequencies

Hydraulic Distribution

For a typical Structurals Testing laboratory, the hydraulic requirements can vary considerably, but are usually on the order of 300 LPM to 1200 LPM of flow depending on the size and the charter of the laboratory. The types of testing programs will greatly influence the sizing of the distribution network.

MTS tries to work closely with our customers during the conceptual stage to determine both the immediate needs and the potential future requirements. We typically make our final recommendation based on performance requirements, anticipated needs and current budgets.

Items that are considered when designing a hardline system:

Facility issues.
Total length of the main circuit and any branch lines.
Pressure drops that will occur reducing performance levels.
Stainless steel tubing or piping routing to compliment the design of the building.
Hydraulic outlet requirements.
Hydraulic accumulation requirements.
Hydraulic power supply location and electric sizing.
Hydraulic oil cooling requirements and sizing for either air/oil or water cooling systems if required by the customer.
Hydraulic cleanliness of the oil system for maximum performance.

HYDRAULIC SERVICE MANIFOLDS

Reaction Walls and Portal Frames

Most large scale structural testing facilities will consist of some type of strong floor and strong wall reaction mass with a variety of portal frame components to act as secondary reaction frames for custom test configurations. The size and shape of these facilities are typically determined by the testing charter of the laboratory. For smaller scale structural testing laboratories a lower capacity strong floor or reaction bedplate is often used with portable reaction walls anchored to the bedplate.

MTS can assist you in various ways during the planning stages of a new facility or modifications to an existing building depending on the level of support that you require. We can provide simple recommendations based on our experience and the success of other laboratories doing similar types of tests or we can perform design contract studies to help conceptualize the entire project. In addition to early planning or design contract studies, MTS can provide the detailed design and documentation by a registered architectural engineering firm familiar with these types of facilities so that you can have the building constructed with your local contractor. We can assist you throughout the project from the beginning to the end
