Tension - Compression Major Deformation Test of Rubber Vibration Isolator by Shimadzu Autograph Series

The Autograph Series features the ability to freely change test conditions while testing in addition to the reciprocating function (tension - compression).
Shown below is an example of a tension - compression major deformation test, a test popular for evaluating the dynamic characteristics of rubber vibration isolators, executed by the Autograph.
Measurement was taken to record changes in energy loss (absorbed energy) on a hysteresis loop. Load and deformation were applied to an anti-vibration rubber developed for use in the architecture and civil engineering fields, load and deformation were then increased at return point per cycle.

Test conditions

1) Cycle test by means of load control

The above were load conditions at first cycle (+/- 50 kgf). +/- 100kgf, +/- 200kgf, +/- 300kgf and +/-400kgf were applied successively thereafter.

The above were displacement conditions at first cycle (+/- 1 mm). +/- 2mm, +/- 3mm, +/- 4mm and +/- 5mm were applied successively thereafter.

Test results
