1 IPC Global Universal Cyclic Triaxial System The science of testing made easy

2 EARTHQUAKE SIMULATION BLASTING SIMULATION WIND SIMULATION ROAD TRAFFIC SIMULATION RAIL TRAFFIC SIMULATION OCEAN WAVES SIMULATION INTRODUCTION IPC Global is the world leader in innovative design of advanced materials testing systems. The Universal Cyclic Triaxial System is our latest offering, combining decades of experience with ingenuous design in delivering a truly flexible dynamic soils system. Specifically designed to be used in commercial and research laboratories, it is capable of simulating real world conditions such as earthquakes, blasting, wind, road and rail traffic and even ocean waves. A truly world class testing system that is fully modular and customisable with various upgrade packages and accessories; the Universal Cyclic Triaxial System will meet the most demanding requirements of any laboratory. Flexible and modular, the system is designed to fit any laboratory Using our world renowned IMACS digital controller and UTS Software, the system allows for superior control and data acquisition and advanced analysis The system uses a precision engineered load frame along with IPC Global s Special Application high performance servo valve; providing the perfect platform for precise force and displacement control

3 Universal Cyclic Triaxial System IPC Global s innovation in design has resulted in the system exceeding many servo-hydraulic testing machines but at a fraction of their price. Load Frame & Actuator The IPC Global Universal Triaxial System uses our world class UTM-14P two column load frame, with a servopneumatic actuator with internal displacement transducer. The high performance servo valve allows a sinusoidal loading frequency up to 70Hz and can reproduce any wave shape or vibration signature. This makes the system ideal for simulating and investigating earthquake tremors as well as quantifying liquefaction potential of soils and silts. Distribution Panel Light weight and easy to follow diagrammatic distribution panel, which can be wall mounted for easy access. Air/Water Bladder Provides confining pressure to the sample and is capable of operating continuously at a maximum pressure of 1000 kpa. Triaxial Cell The system uses IPC Global s world class triaxial cell, designed with a high quality clear acrylic chamber for maximum visibility and safety. The cell has an attractive and practical design with the top and base precision machined from high quality anodised aluminium. It has an easy access test chamber with three easy-turn knobs and five volume-change valves aligned on one side for maximum convenience. A Teflon coated loading shaft runs inside double linear bushing with special seals for minimum friction. Automatic Volume Change Apparatus The apparatus is used for measuring the volume change of a soil specimen, provides back pressure to the soil specimen, has limitless capacity, is accurate to better than ±0.05 ml and is easily de-aired in seconds. The Universal Cyclic Triaxial System is designed with closed loop control of axial load, cell pressure and back pressure. The combined pressure/ volume-change apparatus with autorefill allows tests to run uninterrupted for infinite volume change. Servo Reservoir Assembly IMACS Controller The heart of all IPC testing systems is the Integrated Multi-Axis Controller System (IMACS), which provides the user with revolutionary, leading-edge performance, delivering unparalleled levels of control and the ultimate in flexible data acquisition. The IMACS provides real-time control with excellent waveform fidelity from integrated acquisition and control functions, at speeds of up to 5kHz simultaneously on all channels. It uses 4x oversampling for low noise performance and has autoranging resolution of up to 20bit. With the IMACS you have total confidence in measurements, with analogue inputs auto-calibrated on power-up. Flash based firmware and USB communication ports at 10Mb/s gives enhanced connectivity and allows for field updates of all modules.

4 UTS SOFTWARE IPC Global s purpose designed UTS software is based the powerful and professional Delphi with numerous applications for testings soil and unbound granular materials. The software displays real-time graphs for monitoring the specimen under test, displays live transducer levels and allows playback of vibration signatures with up to 40,000 data points for maximum resolution. UTS PLAYBACK FILE CONVERTER Import or create your own custom vibration signatures APPLY SIGNATURE AS CYCLIC SHEAR PARAMETER Simulate real world events from violent earthquake to sedate ocean waves. TUNING PARAMETERS Easy to navigate menus to allow you to set up your test parameters with minimal hassle. SATURATION STAGE Flexible, it allows for different test methods to be used including B value. It is capable of automatically applying incremental cell, back and pore pressures. CONSOLIDATION STAGE Colour coded graphic displays for Cell Pressure, Back Pressure, Pore Pressure and Sample Volume Change versus Time. STRESS PASS RESULTS Allows you to set up and monitor all of your test transducers with real time mapping of test results in an easy to read graphical interface. MONOTONIC SHEAR RESULTS Concise and meaningful data display with selectable transducer readings. CYCLIC SHEAR RESULTS Shows Axial Stress in Compression, Axial Stress in Extension, Double Amplitude Axial Strain, Axial Strain in Compression and Axial Strain in Extension.
