Introduction
The inertial shaker (DYN-IS-10) is used for relatively small structures requiring excitation in low-frequency bands. The shaker is directly connected to the structure and the inertia motion of the shaker mass provides the necessary forces to the structure. The shaker has a small, lightweight design that provides high mobility. For this reason, it is suitable for use as a portable shaker.
General Information
Unpacking and Inspection
DynaLabs products provide adequate protection for undamaged products to be
transported. Document the damages that occur indirectly during the transport
and contact the customer representative. Check all components of the shaker.
If there is a defect, please contact us.
System Components
DYN-IS-10 has the following components:
- Electrodynamic Shaker Body
- Amplifier (DYN-SA-150)
- Power Adapter
- Signal Cable
- Stainless Bolt for Mounting (M3X45)
- Sensor Mounting Adapter
- User Manual
Theory of Operation
DYN-IS-10 is an electromagnetic actuator. Electromagnetic actuators are
basically voice coils consisting of a magnet and coil. The moving element can
be a coil or magnet depending on the design requirements. The moving element
is usually suspended by an elastic spring. DYN-IS-10 has a stationary coil
(drive coil) whose current is controlled to produce vibration. The stationary
magnetic field is produced by a magnet.
Specifications
Outline Drawing
The dimensional properties of DYN-IS-10 shakers are given below. All
dimensions are in mm.
Operation and Installation
General
The general shaker connector configuration is given below.
The Gain Knob is a push-pull and rotational switch. The amplifier is in External Signal Mode when the Gain Knob is pushed in and the amplifier is in Internal Signal Mode when it is pulled out. In order to protect the amplifier from electrical problems, it is advised to turn the Gain Knob counterclockwise to the lowest gain position before connecting the external signal cable or before changing operational modes.
External Signal Mode:
Connect DC power source and drive signal to the shaker power input and signal
input respectively. Start the external signal source. Adjust the Gain of the
amplifier by turning the Gain Knob clockwise.
Internal Signal Mode:
The amplifier can generate sine signal from 1Hz to 15kHz with 1 Hz increments
that the user can adjust with the Sine Frequency Generator Switch. Connect the
DC power source and drive signal to the shaker power input. Pull the Gain Knob
out.
Raise or lower the Sine Frequency Generator Switch to the desired Sine
frequency. Adjust the Gain of the amplifier by turning the Gain Knob
clockwise. The frequency of the generated sine signal will be visible on the
LCD Screen. 
Power Requirements
DYN-IS-10 has an external power amplifier that is powered by its power
adaptor. Please note the output voltage and current ratings of the adaptor if
a replacement adaptor is to be used.
Cooling
DYN-IS-10 does not require forced cooling. Air convection cooling is
sufficient for the force levels given in the specifications.
Frequency Response
The DYN-IS-10 has a relatively flat force response of 10N. The following
figure shows the Force (Newton) over the applied Voltage (Volt) frequency
response of DYN-IS-10.
FOR FIXED FREQUENCY SINE TESTING, THE APPLICATION OF VOLTAGE E LEVELS ABOVE 1V FOR LONG DURATIONS (>1MIN) CAN PERMANENTLY DAMAGE THE SHAKER. THE SHAKER SUSPENSION NATURAL FREQUENCY IS ABOUT 19 HZ. ESPECIALLY FOR FIXED FREQUENCY SINE TESTING, THE USER SHOULD ALWAYS LOWER THE GAIN FOR THE FREQUENCY BAND OF 5-30 HZ. OTHERWISE, DUE TO THE HIGH RESPONSE OF THE SHAKE R AROUND ITS RESONANCE FREQUENCY, VERY HIGH AMPLITUDES OF VIBRATION WILL OCCUR AND PERMANENTLY DAMAGE THE SHAKER. THE INTERNAL SINE SIGNAL GENERATOR SUPPLIES A CONSTAN T VOLTAGE OF 1VAC. PLEASE LOWER THE GAIN IN THE VICINITY OF THE NATURAL FREQUENCY AS HIGHLIGHTED ABOVE.
Mounting Interface
Maintenance and Troubleshooting
The DYN-IS-10 shaker is a sealed device requiring no maintenance if the operating instructions described in this manual are followed. Repair of the coil, exciter body or magnet core should not be attempted. Please return the shaker to DynaLabs for proper repair.
Safety
Please ensure that this manual section is reviewed and understood prior to
installation, operation or maintenance of the equipment. The danger of
electrical shock or fire always exists in electrical equipment. The DYN-IS-10
Inertial Shaker is designed for safe operation. Safety features such as
electrical insulation on outer surfaces are provided for the safe operation of
the shaker system. Always monitor the applied voltage to the amplifier and
shut down the shaker if the temperature of the shaker body rises drastically
or smoke is observed from the shaker due to high voltage levels applied.
Grounding
The shaker is internally grounded via the power adapter. However, if further
grounding is necessary a grounding socket is available on the shaker as shown.
Appropriate grounding cable is also supplied with the
shaker.
