Dynamic & Fatigue Testing MachinesHybrid Test System Series LFMHybrid – WALTER + BAI

Combine according your Requirements
Often the force requirements for fatigue applications are lower than for monotonic testing. This
test systems offers you to combine the correct fatigue rated servohydraulic actuator size with the
needed static force rating. By selecting the suitable servohydraulic actuator you will minimize
your power consumption and increase your lab efficiency.
When your selected fatigue actuator is with lower force than the electromechanical drive we offer the connecting adapter to bypass the actuator for static testing or alternative the piston rod
clamping system withstanding the maximum static force.
Reliable & Durable
w+b Hybrid Test Systems combines proven load-frame design with additional features for static to dynamic testing application using high quality components and assemblies coupled with a
generous dimensioning.
Versatile
This test systems can be configured to different force capacities with a variety of grips & fixtures,
extensometers, environmental simulation accessories and other components to meet the exacting test needs from quality control to research and development.
Latest Control Technology
The Hybrid Test Systems are closed loop controlled through the latest high-resolution, high-speed
digital control system PCS8000. The PCS8000 ultra-high-speed closed loop control and data
acquisition rate on all channels combined with 24-bit high resolution transducer conditioning
rate is achieved by a 64-bit processor running at 1 GHz.
Advanced Closed-Loop Control
As control channel available are any connected inputs as well as virtual (calculated) channels that might open many new opportunities to your application. The versatile concept of the
PCS8000 is based on latest technology and supports applications with virtually no limits.
Powerful & Electromechanical Drive System
The load frames are equipped with belt drive system with powerful, lifetime lubricated servogearbox providing low belt speed for silent and long-term operation combined with exceptional
low minimum speeds control and best stability when operating the machine at high speed.
The machine is controlled by a brush-less high responsive, maintenance-free AC servomotor to
drive.
Space Saving
These compact tests systems are ideal for any lab that needs to perform a wide range of different tests. The machine occupies a very small area compared with installing a monotonic and an
additional fatigue rated testing machine.
Cost Effective
The LFMHybrid reduces your investment compared with two independent machines.
Additionally, your future maintenance costs, calibration expenses and IT costs will also be
reduces.
Energy Efficient
These test systems makes it possible to select the suitable drive system for your related tests.
When operating the machine with the high-efficient AC drive for monotonic testing you will reduce your energy consumption and increase your efficient.
Operator Safety
Our Hybrid series of test systems fully comply with the safety requirements of the EC Machinery
Directive and are supplied with the related EC Declaration.
Specimen Safety
Specimen protect function prevents your specimen from being damaged during setup and gripping. The Test System is protected against overload and provide the ability to set limits for load,
crosshead travel, strain or any other connected transducer preventing damage to your system,
load cell and grip or fixtures. Mechanical end-stops and adjustable travel limits stop the crosshead at set points.

Machine Safety
Provides highest level of machine safety including overload protection of the frame, overload
protection of the load cell, maximum and minim crosshead travel switches, two-channel safety
circuit according to the machinery directive.
Crosshead Clamping
For models with high dynamic forces and for increased life-time the LFMHybrid is offered with
additional crosshead clamping to the two guidance column. When the crosshead is clamped to
most of the test force is absorbed by the two guidance columns reducing the force to the ballscrews considerable.
This passive clamping system can be unclamped for tests performed with the electromechanical
drive. A well-defined clearance ensures that the crosshead can move without friction.
Expandable
Testing Machines powered by PCS8000 you will be ready for your test demands of today & tomorrow. These test systems can be equipped with up to 26 amplifier cards for control or data-acquisition and up to 20 virtual channels operating at full rate. All physical and virtual channels
can be used as data-acquisition as well as control channels. Additional 24 digital outputs and 16
digital inputs to control external devices are provided.
