hi PJ;
Sorry, that was the equasion that I used, at least I have a varification of that.
I think I can use an oscilliscope (If the company hasn't dumped it!)...Just need to pursuade them to get an accelerometer!!
Thanks a lot for your help..
Regards,
Mark.
Hi Hui,
Careful now vibration is very complicated and it is always best to start at the beginning to gain full knowledge of your subject before researching.
Try referring to a basic textbook first - this will also give you a good starting point for your project.
I can reccommend Mechanical...
Dear Savior...
I am trying to calculate the natural frequency of a bellows compressed under load.
the best calc i have used is Fn=2Pi x SQROOT(k/m)
My questions are :
1, Does anyone know of a better calc?
2, When I finally come to being able to check the calc through testing, what instrument...
Hi,
Can anyone help me with a tough application?
I have designed a shear testing jig which is basically 2 plates being pulled in oposing directions.
The test piece is bonded between the plates.
I need to select an adhesive which will allow me to run shear tests on various materials and...
JPV7,
You have really answered your own question, When you say you want to do more of an R&D hands on job.
The best thing you can do is look around your current work place and see if the R&D test side is what you want (if you have one)if it is, request a transfer.
There are a lot of aspects to...
Johnboy,
The answer is a simple bending moment equasion.
Imagine one of the legs is fixed work out the total force and divide by 2.
IE. 100N at ????m (distance from pivot - Take the pivot as being where your clamps jaws are.
basically Force x Distance.
Hope this helps.
Mark.
DGP,
I work for a massive Global organisation in mechanical engineering. We currently use 'Helix Design System' (Dont even bother looking it up). The point i am putting across is, We are so annoyed with using this system we decided to change it, (cut a long story short) the company on a Global...
Hi BLN,
Thanks for your reply I have already looked at 2 of these standards with no luck. With your jig was there any limit or tolerance needed between your punch & die in the shear plane or does it have to just be as close as possible?
Is there any standards for this type of thing, or general...
HI people,
I'm currently involved in a project where the goal is to design a shear testing jig.
I have looked through various standards but to no avail.
Does anyone know where i can find any information on designing such a jig to get accurate results for testing plasics.
I have already done a...
