VM-VDI2230-BOLT-001: Annex B, Example B1

Annex B, Example B1 of VDI 2230 Part 1:2015: the central bolt between the piston and piston rod of a hydraulic cylinder (tapped thread joint, concentric clamping and concentric loading, pulsating axial load), used to check the resilience, embedding, preload, working stress, fatigue, surface pressure and length of engagement results of the VDI 2230-1 single-bolt calculator point by point.

VM-VDI2230-BOLT-007: Connecting-rod necked-down bolt, dynamic load check

A textbook worked example of a connecting-rod necked-down bolt (M10-10.9 through-bolt joint, static and fatigue check), used to check the resilience, load factor, preload loss due to embedding, assembly preload, fatigue stresses and safety margins of the VDI 2230-1 single-bolt calculator point by point.
