Landmark Test System Site Prep Guide Facility Preparation 9
The dynamic response characteristics of the foundation should be limited to low
levels so that the accuracy and performance of the MTS equipment mounted on
the foundation will not be affected. An improper foundation mass can affect
equipment performance. This is particularly true in strain-controlled, low-
frequency or strain-controlled monotonic testing.
If you have any questions or concerns about the suitably of your foundation,
contact MTS.
Floor Loading Considerations
Once the final layout for your system laboratory has been developed, the
dimensional and weight information for the various system components should
be supplied to the building facility personnel to ensure that proper building
loading and vibration considerations have been evaluated.
The load unit comes equipped with vibration isolators that are designed to
distribute the load into the floor and to provide isolation from excitation caused
by movement of the actuator rod. These vibration isolators will be found in a
carton which will accompany the load unit. This carton also contains other
accessories basic to load unit operation. If high cycle fatigue testing is to be
performed, place the load unit such that vibrations do not excite undesirable
resonances or cause excessive loads in the building structure.
Hydraulic power units rest on a special base flat on the floor. Resting flat on the
floor provides maximum loading distribution. See
“Model 505.07/.11
Specifications” on page 18 and “Model 505.20/.30 Specifications” on page 20.
A review of the final installation plan by building personnel is recommended to
check static and dynamic floor loading.
Mechanical Shock/Vibration
Where impact testing is performed or in higher speed fatigue testing, cyclic loads
and simple shock pulses can be introduced into the laboratory floor. Adequate
isolation of the load unit is often possible with the supplied vibration isolators.
However, in some cases, an optional air bag isolation device might be required.
Contact your MTS representative for additional details.
Electrical Power Distribution
The input line voltage to the Landmark System must be adequately rated for the
loads under which the system operates. Size the power system with adequate
reserve for future equipment additions and installation expansion. Both the HPU
and the console controls must be considered in the distribution system, with
emphasis on providing “interference free” electrical power to the controls. Plan
routing of power cables away from instrumentation cables (for example,
transducer cables). Avoid long parallel runs of power cables in close proximity to
instrumentation cables. Power cables should be separated from instrumentation
cables by 1 to 3 ft (0.3 to 1 m).
