Vdi 2230 2021 High Quality

The external load or the component geometry is asymmetrical. This introduces a bending moment into the joint, causing uneven pressure distribution across the clamped interface. This requires more complex calculation using substitution deformation cones or cylinders. 3. The 13-Step Calculation Procedure

Refined algorithms for determining the compression zone (deformation cone) in eccentric joints. Delivers more realistic values for component compliance ( δMdelta sub cap M ) in highly complex geometries. vdi 2230 2021

: Calculating required assembly preload while accounting for tightening technique scatter. The external load or the component geometry is asymmetrical

The guideline treats the bolted joint not as isolated parts, but as an elastic system. When a bolt is tightened, it stretches like a spring, while the clamped clamped parts compress like a second spring. VDI 2230 analyzes how external working loads redistribute through this elastic system. 2. Key Updates in the 2021 Revision : Calculating required assembly preload while accounting for

Accounting for scatter in tightening methods. 2. Key Changes and Updates in VDI 2230-1:2021

The plates or parts being held together compress under the bolt's tension.

Confirm that the thread engagement length is sufficient to prevent thread stripping before the bolt breaks in tension. 5.
