      Will anybody please tell me that impact of vibrational force of 1g is greater or centrifugal force of 1g is greater? please reply with any reference or proof.........
      thanks in advance..........

      What do you think?
      What are your reasons?

      I don't have a proper answer to your question. But when we talk about vibration, we should specify if it is vibration in just one axis, as produced by electrodynamic shakers, or is it omni directional vibration as produced by a HALT chamber. Both are very different and 1g vibration produced by an electrodynamic shaker is very much more stronger than the same produced by a HALT chamber.

      1g = 9.80665 m/s[SUP]2[/SUP]

      Is there something confusing about this?

      BTW, 1g is not a force, it is an acceleration.

      It depends on the material, whether or not a centr. forge has more impact. Imagine soft material, which may be deformed permanently.
      Generally I a vibration has more impact, as it is a sinus wave like movement which may easier lead to fatique, because of the internal friction energy that is generated by the movement, so the accelleration (force) will run from plus to zero to minus. If you would connect a temp sensing element, you will notice that the temp. will raise more when vibration energy is induced to the product, than when a single constant one directional g force is induced.
