| Summary: | A general purpose vibration test system has been
developed to provide a testing platform for electronic devices.
This paper presents the design of the shaker table for the
platform-testing base where an electronic device will be placed
and excited by the vibration exciter. Three design models are
first analyzed their natural frequencies and the corresponding
mode shapes. The model with the lightest weight and the highest
first natural frequency is then selected to be manufactured. This
selected shaker stable can be used in a frequency range of
service up to 2500 Hz and behaves as a rigid body when it
vibrates. The maximum dimension of the electronic device that
can be placed in the shaker table is 15 cm square. This paper
also provides the general frequency range limitation when the
vibration test is used at constant displacement or constant
acceleration test. The suggested frequency ranges satisfy all
limitation requirements of the shaker. |
