Bolt calculation according to VDI 2230
Bolt calculation according to VDI 2230
(OP)
Hello colleagues
Is there anybody famillar with VDI 2230 standard and calculations?
I must perform calculations of bolted joints and I am little bit confused with some points of mentioned VDI... i.e. How to include influence of special type of washer (Nordlock, Schnorr, Helical spring washer, etc.) and special type of nut (Flowtrap by Flowdrill, Riveted nut - RIVNUT, etc.)
Have you any tips for friction coefficent of powder coating - powder coating, powder coating - Zinc coating?
Scheme of bolted joint attached
Thank you and have a nice day
Radek

Your best option is to conduct some torque vs. tension tests using a force washer or ultrasonic bolt gage.

This look like a problem, because our customers requier calculations according to VDI and they want using mentioned special washer to avoid self-opeing.
Is anybody able to check my excel sheet with VDI "algorithm"? Because I'm not sure if equations and steps are used right.
Problem - If I want to a special type of washer, I cannot perform calculations according to VDI, because they are out of range VDI.
Solution - Replacing of special washers to ordinary could be simplification for calculation, right?
