). The new version provides updated tables for friction coefficients and material properties, reflecting the performance of modern coatings and high-strength fasteners (such as grade 14.9 or higher).
The VDI 2230 guideline, specifically titled Systematic calculation of highly stressed bolted joints ," is the internationally recognized standard for designing and verifying high-strength bolted connections. While the foundational VDI 2230 Blatt 1 (covering single cylindrical bolts) was most recently updated in late 2015, the 2021 update is primarily associated with revised Reference Tables and supplemental guidelines like Blatt 2 (multi-bolted joints) or Blatt 3 (safe assembly). Core Calculation Methodology vdi 2230 2021
VDI 2230:2021 provides a comprehensive, practical method for designing and calculating highly stressed bolted joints, covering preload, external loads, joint stiffness, friction, safety factors, and verification steps. It standardizes procedures for reliable bolt selection and joint dimensioning in mechanical engineering. While the foundational VDI 2230 Blatt 1 (covering
