Represents the important components contributing to the mass, natural frequency
of an exhaust system and mounting structure respectively.
These relative motions at a given natural frequency
create a deformed shape, also known as the eigenvector or mode shape.
This study was made to have better understanding about the change in the natural frequency
due to changing the organic part of the bone matrix.
The natural frequency
components and cable forces measured by the application D-Viewer were compared with the results measured by the application Orion-CC.
It can be observed that the higher the values of Mw, Mz, and PDI, the lower the natural frequency
values; however, no conclusive correlation can be established due to the closeness of some of the MWD data for different stability indices.
Especially for the scoured bridge, its natural frequency
is sensitive to the exposure of the bridge foundation.
gave an equation to obtain the difference in the squared natural frequency
of the rth mode in (6) by neglecting the difference in mode shape arising from damage.
Since the measuring of natural frequency
is easier than that of change in structural damping, change can be detected from dynamic analysis using natural frequency
and mode shapes.
LATE TIME RESPONSE IN TERMS OF THE NATURAL FREQUENCY
The analysis include two steps: one step is static analysis using Newton-Raphson algorithm, the other is natural frequency
extraction analysis of the structure pre-stressed in the first step.
Additionally, DM3 boasts vibration and temperature insensitivity and has a low natural frequency
to absorb external vibration.
The other factors included transient voltage amplification due to the natural frequency
of the 11kV system at Jalan Bani Bu Ali being very close to the natural frequency
of the 33kV system at Jalan Bani Bu Ali to which it is coupled.
