SM-105-MP
SHOCK TEST MACHINE
Description
Carriage
The SM-105-MP is a microprocessor controlled,
pneumatically powered shock machine for accurate,
repeatable laboratory and production impact testing of
specimens up to (50 pounds) 22,7 kg. With
appropriate pulse generators, it will produce half sine,
sawtooth, and square wave pulse shapes to meet
exacting military and industrial specifications or
individual test requirements. Generated waveforms will
comply with typical military specifications, such as MILSTD-202, MIL-STD-810, and MIL-STD-750. The SM105-MP is completely portable and requires no special
floor preparation or bolting. The only locational
requirements are availability of compressed air,
(115 V/ 60 Hz - US Standard) or 230 V/ 50 Hz (European
Standard) power, and a floor that is reasonably level.
The floor must support the weight of the machine plus
the test specimen and provide a nominal safety factor to
accommodate minimal shock loads. The machine may
be moved with a fork lift truck.
The carriage is a conical shaped aluminum casting with
mounting surfaces machined to dose tolerances. lt has
been designed for optimum strength-to-damping ratio.
Steel inserts provide for attaching specimens or fixtures
to the carriage, as shown on the back cover.
Base
The base assembly functions as an inertial mass and
reacts with the falling carriage to generate a shock
pulse. The assembly is made of high-strength
reinforced concrete, encased in a steel jacket, and is
supported on tour air mounts. It supports a carriage and
guide rod and contains a pneumatic cylinder assembly
an electronic pneumatic control system, and a control
panel. The machine is shipped completely assembled.
Air Mount Supports
The pneumatic supports, built into the base of the
machine, are inflated by the machine's compressed air
supply and effectively isolate impact forces, reducing
their transmission to the floor. Air pressure and inflation
are controlled by a regulator and pressure gauge and
may be adjusted to suit specific bad and test conditions.
Shock Pulse Generators
A variety of elastomer pads, lead pellet molds, and
pneumatic pistons for generating halt sine, sawtooth,
and square wave pulse shapes are available for this
machine. The pads are easily changed to meet a wide
range of pulse requirements. Elastomer pads have
proved to be the most economical and versatile
generators for half sine wave forms. Molds are supplied
for casting lead pellets to generate terminal peak
sawtooth pulse shapes.
Maintenance
RMS / AVEX pneumatic machines are designed and
constructed for long Service life and minimum
maintenance. The pneumatic, electronic, and electrical
systems are arranged for easy access by maintenance
personnel or technicians.
Controls
The machine's pneumatic components are controlled
by a self-contained microprocessor. A key pad,
conveniently located on the top control panel, programs
the microprocessor for charge pressure, drop height,
braking, cycle count, and instrumentation trigger.
Electrical power is provided by the top control panel key
lock switch. Depending on the number of cycles
programmed, the microprocessor will direct the
machine to initiate one or multiple drop cycles at a rate
of up to 8 cycles per minute. A valve plate supporting the
assembly of valves, pneumatic and electrical
connections, and microprocessor is mounted on the
machine to provide easy access for maintenance and
adjustments.
Operation
The machine is powered by compressed air with
pressure ranging from (100 to 125 psi) 7 - 9 bar.
The following describes a typical drop cycle:
Compressed air is introduced to the lower side of the
piston, raising the carriage to a selected height as
determined by microprocessor programming. Once the
height is reached, the holding brake is applied. The lift
air is dumped and compressed air is introduced to the
upper side of the piston to a desired "charge” pressure,
which is measured by a transducer. As soon as the
desired charge pressure reaches the proper amount,
the microprocessor actuates the valve which releases
the pressure on the holding brake. The carriage is then
driven downward by the charge pressure, impacting on
a pulse generator mounted on the anvil. Upon impact,
the microprocessor directs the brake to be actuated,
holding the carriage in a rebound position and
preventing secondary impact. At the same time, the
microprocessor will trigger the sweep of an oscilloscope
or other instrumentation for recording the shock pulse.
