🧮 在线计算器：VDI 2230 Bolted Joint Calculation — The full 14-step calculation chain (R0–R13), with six strength checks. Full worked example: tapped-thread joint (ESV) This article is a counterpart to the DSV example (article 8) . It highlights the differences unique to ESV: $w = 2$, $E_M = E_{BI}$, the cone-angle formula Eq. 42, and the R11 engagement-depth check. Engineering problem statement A bolt is screwed from the top into a cast-iron housing (grey cast iron GJL-250), fixing a steel cover plate. ...

🧮 在线计算器：VDI 2230 Bolted Joint Calculation — The full 14-step calculation chain (R0–R13), with six strength checks. Full worked example: through-bolt joint (DSV) This article ties all the theory of the previous 7 articles into one complete calculation chain. Using a concrete engineering case, we go through every step of R0–R13. Engineering problem statement A steel flange joint using a single bolt to fix a cover plate. The design requirements are: ...
