The scope of VDI 2230 Part 1 is to provide a systematic approach to the calculation and design of bolted joints, taking into account the relevant factors that influence their behavior under various loads. The purpose of this part is to provide guidelines for the design and calculation of bolted joints in mechanical engineering, including the selection of bolts, nuts, and washers, as well as the verification of the joint's strength and safety.
Unlike basic engineering formulas that treat bolted joints as simple rigid bodies, VDI 2230 acknowledges that bolts and clamped components act like complex elastic springs. The guideline provides a highly accurate mathematical framework to calculate forces, deformations, and safety factors. Why is VDI 2230 Part 1 the Industry Standard? Axial Working Load (The external force trying to
Unlike basic engineering formulas that treat bolted connections simplistically, VDI 2230 accounts for complex elastic deformations, thermal expansion, tightening friction variations, and alternating operating loads. It focuses specifically on single-bolt connections, establishing the baseline physics used to analyze complex, multi-bolt patterns (which are covered in Part 2).
