Calculating Cyclic Energy from Acceleration (Relative)

Click For Summary

Discussion Overview

The discussion revolves around the calculation of cyclic energy applied to a material under two different conditions of acceleration and frequency. Participants explore whether it is feasible to relate the energy applied in these conditions and how to quantify it.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • One participant, Munnaz, presents two conditions involving different accelerations and frequencies, seeking to understand if the energy applied can be calculated and compared between them.
  • Another participant questions whether "cyclic energy" refers to the material being spun in a centrifuge, indicating a need for clarification on the nature of the forces involved.
  • Munnaz clarifies that the conditions involve vertical accelerations experienced by the material on a vessel and a vibrating table, not centrifugal forces.
  • A further inquiry is made regarding the nature of the vertical accelerations, asking if the 1G acceleration is a peak-to-peak measurement and whether the material experiences free-fall or additional stresses during the vibrations.

Areas of Agreement / Disagreement

Participants have not reached a consensus on how to relate the two conditions or the specifics of the cyclic energy involved. There are multiple viewpoints regarding the nature of the forces and measurements being discussed.

Contextual Notes

There are unresolved questions about the definitions of cyclic energy, the measurement of accelerations, and the potential effects of the forces on the material, which may influence the calculations being considered.

Hello,

I am looking at relating two situations under which cyclic energy is applied to a material.

Condition 1: A material has been subjected to a force of 1G at 0.1Hz for 47 days.
Condition 2: The same material has been subjected to a force of 4.5G at 60Hz for 3600Seconds.

Is it possible to calculate the energy applied under both conditions and relate them to one another (i.e. condition 1 has applied 200% the energy applied under condition 2)?
or
Can they be directly related to each other. For example: Under condition 1 the material experiences 406,080 cycles therefore a cumulative total of 406,080G. Under condition 2 the material experiences 216,000 cycles therefore a cumulative total of 972,000G. Therefore condition 2 experiences 240% times the energy condition 1 experiences.

Is either of these possible or is there another way to relate them to one another?

Thanks in advance.

By "cyclic energy" do you mean that the material was spun in a centrifuge at the indicated acceleration?
 
Hi Dale,

Not centrifugal force. Condition 1 is on board a vessel in the ocean and the other is on a vibrating table. Both vertical accelerations.

Regards Munnaz
 
So if the accelerations are vertical and they are cyclic then the magnitude must vary over time. So is the 1 g mentioned a peak-to-peak acceleration or what? Does the material free-fall down?

Also, does the acceleration involve any "squeezing" or "flexing" of the material other than what happens simply due to gravity and being pushed up? In particular, the vibrating table does not seem like it could be done without some additional fixation and stress in the material.
