Understanding VDI 2230 Part 1: A Comprehensive Guide to High-Strength Bolted Connections
The fundamental concept behind VDI 2230 is treating the bolted connection as an . Both the bolt and the clamped parts behave like springs under tension and compression. 1. The Joint Diagram (The Spring Model)
): Factors in the slight flattening of surface roughness over time, which reduces preload. R4: Determine Load Factor ( Understanding VDI 2230
The standard requires solving multi-variable transcendental equations and complex geometric integrations for eccentric joints.
) required based on the tightening technique (e.g., torque wrench, impact wrench, or hydraulic tensioner). The standard utilizes a tightening factor ( αAalpha sub cap A ) to account for friction variability.

is a guideline issued by the Association of German Engineers ( Verein Deutscher Ingenieure ). Part 1 of the guideline, titled "Systematic calculation of highly stressed bolted joints - Joints with one cylindrical bolt," focuses specifically on concentric and eccentric bolted joints under tensile and shear loads.
