VDI 2230 (005): Clamped-Parts Resilience δP and the Cone Model
🧮 在线计算器：VDI 2230 Bolted Joint Calculation — The full 14-step calculation chain (R0–R13), with six strength checks. Clamped-parts resilience δP and the Rötscher cone model The previous article settled how “soft” the bolt is ($\delta_S$); this one answers how “soft” the clamped parts are ($\delta_P$) — the other half of the force ratio $\Phi$ calculation. 1. Why is δP harder to compute than δS? The bolt resilience $\delta_S$ can be broken simply into series cylindrical segments that add up. But the clamped parts are a completely different case — the standard states (VDI 2230:2015, §5.1.2, p.45): ...
