VDI 2230 (004): Bolt Elastic Resilience δS Explained
🧮 在线计算器：VDI 2230 Bolted Joint Calculation — The full 14-step calculation chain (R0–R13), with six strength checks. Bolt elastic resilience δS — breaking the bolt into a chain of cylinders The previous article set up the framework of the spring model; this article provides the first concrete number for the numerator and denominator of the force ratio $\Phi$ — how “soft” is the bolt itself? 1. Basic principle: series cylindrical segments VDI 2230 treats the bolt as a tension spring made of several series cylindrical segments of different cross-sections (VDI 2230:2015, §5.1.1, Bild 6). ...
