【General Vibration -Proof Design】
Generally, set up the spring constant of the support
(including dampers) from the mass of the floating part that
requires vibrations and required vibration characterisitics.
Ex) Optical Disc Mass : 310ｇ
Supporting Points : 3points (equal)
Target Resonanc Frequency : 20Hz
Substituing the above formula (1)
Spring Constant of the Support : k=1.64N/mm

～Target Resonance Frequency～
Varies depending on purpose, like Consumer Electronics, Automobile
etc., but take into account the motor rpm, internal/ external
oscilliation frquency. Furthemore, it is affected by the enviormental
temperature.
① Based on a data suh as the one on the right that is obtaind

from the vibration transmission chracteristics of the actual
equipment or mass model, adjust the matrial, hardenss ,
shape and etc.
Ex) Input Acceleration : 9.8m/s2
Excitation Frequency : 6～200Hz
Sweep Time : 3min/log
