I'm a ME student and I've been studying Machine Elements on this semester. One of the primary topics is Bolted Joints and I was interested to read up more on them. My professor teaches us outdated standards and it seems that the book he uses (the one he wrote) has no reference whatsoever to any other books. I'm in Europe so I am interested in ISO or DIN standards that would outline the calculation of a bolted joint. Also, a book or a guide with examples would be great.
Have a look at the website called Bolt Science (see link below) - there is lots of reference material on there - which should be of interest to you. You could perhaps persuade the professor to buy the software - so that everyone can get up to date. http://www.boltscience.com/ Hope this helps.
VDI 2230 guideline will give you advice on bolt torque calculations.. Also I found these websites which might give you some ideas; http://www.fera.org.uk/pdf/FERA - Dr John Newnham - 22 Nov 06.pdf http://www.hexagon.de/rs/review design guideline VDI2230fda.pdf
Be sure not to use helical split lock washers in ANY bolted joint. These actually make the joint more likely to loosen! Also, as the earlier guys said, BoltScience is a good source of information. They also sell very reasonably priced torque calculators like Torksense.
The principles have not changed and this is very established material. Out dated standards? Doesn't mean there is much wrong with them. On what basis do you think he is giving you less than useful or incorrect information? Can you be clearer what your specific issues are? Perhaps we can help you understand better whether he is steering you in a less than appropriate direction.
gbash: Have a look at http://www.roymech.co.uk, especially the section on screws. You'll find a lot of useful information, including reference to various ISO and DIN standards related to bolts and bolted joints. Sadly, Roy Beardmore, the engineer who created the site, died some time ago. But the site remains, for the time being.
