VDI 2230 (003): Spring Model and Force Distribution
🧮 在线计算器：VDI 2230 Bolted Joint Calculation — The full 14-step calculation chain (R0–R13), with six strength checks. The “spring philosophy” of a bolted joint — the core physical model of VDI 2230 1. The spring model: the physical basis of VDI 2230 The starting point of all VDI 2230 calculations is to model the bolted joint as two sets of springs (VDI 2230:2015, §3.2, p.20): “In this model, the bolt and the clamped parts are considered as tension and compression springs with the elastic resiliences $\delta_S$ and $\delta_P$.” ...
