dear all,
My regular practice is to convert ideas 2d drawings into ACAD readable *.dxf format.
But by using above mentioned options also many times i have found that i am getting some odd or corrupted geometry in Autocad drawings.
Why it is happening?
Is there any external translators avialble...
Dear Sir (Greg Locock),
I am having some doubts. If we have the deflections for the particular force then we can obtain stiffness. Which is that stiffness. in many FEM analysis we use to calculate the stiffness by this method only.
Please guide me !

Dear Robin,
I am agree with the use of ASME code for shaft design. Design for fatigue involves either design for finite life or infinite life. Could u plz specify the life in millions of revolutions? (expected)
I think this above data along with reliability factor will give u the factor of...
dear Modula2,
For my personal interest would you like to share some compressor details? Since i am also working on reciprocating compressor.

Dear Greg & Electricpete,
Thanks for vibration consideration taken into account.
Also i am agree that dynamic stiffness should be considered
while addressing such issues.
One can really think of stiffening the structer in first
shot.

I don't feel that the natural freq of the system should be always greater than excitation freq.
My experience in reciprocating compressors is that while designing the springs we used to keep the system freq less than 10 Hz as my excitation freq is 50 Hz. These compressors are fitted on the...
