: Verify surface pressure at bearing areas to prevent deformation of the clamped parts and ensure the minimum thread engagement length is met. Key Technical Parameters Review of the Application of Design Guideline VDI 2230
The bolted joint maintains its clamping force throughout its operational lifespan. The joint does not slip under shear loads. vdi 2230 part 1 pdf
The standard provides guidance on achieving and maintaining the appropriate preload in bolts, which is crucial for the performance of the joint. : Verify surface pressure at bearing areas to
). Compare this value to the fatigue limit of the thread geometry, accounting for surface finishes and bolt diameters. Step 10: Check Surface Pressure ( pmaxp sub m a x end-sub The standard provides guidance on achieving and maintaining
). This determines how the external working load partitions into an additional bolt load ( FSAcap F sub cap S cap A end-sub ) and a compression reduction load ( FPAcap F sub cap P cap A end-sub Step 5: Calculate Assembly Preload Limits Determine the maximum and minimum assembly preloads ( FM,maxcap F sub cap M comma m a x end-sub FM,mincap F sub cap M comma m i n end-sub ) while accounting for the tightening factor ( αAalpha sub cap A
