What (e.g., torque wrench, impact, hydraulic tensioner) will your assembly team use? Share public link

: Determine the required bolt size based on the minimum assembly preload ( FMmincap F sub cap M m i n end-sub ) and maximum assembly preload ( FMmaxcap F sub cap M m a x end-sub

The core idea of VDI 2230 is to move beyond simple, rule-of-thumb calculations and provide a rigorous, physics-based method for analysis. It assumes that transverse loads are transmitted by friction between the clamped parts, meaning the bolt is primarily subjected to tensile forces and bending moments. vdi 2230 part 1 pdf

Practical application tips

The properties of materials used for bolts and the parts to be joined are discussed, which is essential for determining the strength and durability of the joint. What (e

When a bolt is tightened, it stretches elastically, acting like a extension spring. Simultaneously, the clamped components compress like a compression spring. The initial clamping force applied during assembly. Resilience ( δBdelta sub cap B δPdelta sub cap P ): The spring constants (flexibility) of the bolt ( δBdelta sub cap B ) and the clamped parts ( δPdelta sub cap P 2. Force Distribution Under Working Load When an external operational load ( FAcap F sub cap A

acts as a tension spring, stretching as it is tightened. Practical application tips The properties of materials used

No tightening method is perfectly precise. The torque method, angle-of-rotation method, and yield-controlled tightening all yield different levels of preload accuracy. VDI 2230 accounts for this using the tightening factor ( αAalpha sub cap A ). A lower αAalpha sub cap A

Ensuring sufficient clamping force remains under maximum external load.

Several third-party websites offer PDFs of VDI 2230, often for free or at a low cost. These can be a tempting resource.
