There are three types in frequency response accelerometer; one is lightly damped piezo type, another is oil damping strainguage type and The third is electro induction type accelerometer within elec tromagnetic damping.
The usable frequency range of lightly damped accelerometers is limited to 0.2 of their mounted natural frequency for amplitude distortion of less than 5 percents.
There have been situation where the measured motion contains unforeseen high - frequency
components, which are regarded as such due to the accelerometer transfer function.
There are sevcral way to overcome amplitude distortion of the higher than antieipated fre-
qucncy components:
(Ⅰ) to make use of the accelerometer with natural frequency three times and more as high
as the measured frequeney,
(II) to establish data-analysis techniques which .will aeeount for the amplitude distortion,
(Ⅲ) to set up a notch filter cireuit which has a transfer function that is the reciprocal of
the accelerometer transfer function, and so on.
This paper makes a report of the method as to
(Ⅲ), i. e., set up a few notch filter cir cuits, it is diseussed what happens when the transfer funetions are in discord as to natutal
frequency of the filter and accelerometer damping vs. filter damping.
And especially as for the cantilever strain gauge type accelerometer made by oneself with ease, it was compared and discussed between the ideological value and the experimental value of actual designed circuit in case of the mismatching of the transfer functions, and it was considered whether to be practicable or not, the result of which was as following; the use- ful frequeney range of the accelerometcr can be extended to near resonance if (a) the aceel-
erometer mounted natural frequeney and the filter center frequeney are matched within ±2 percent and (b) the damping ratios are matched within two factors.
Therefore, we obtained the good result in improvement for ex' ending frequency response characteristies of accelerometers.
