Bolt Pre-selection (004): A Physical Look at Bearing Pressure
🧮 在线计算器：Bolt Pre-selection Calculator — Fast sizing with the Kübler equation; supports a design mode and a check mode. Introduction: the rubber-band-and-sponge model To fully understand the physical logic behind the “bearing-pressure check”, we can picture the bolted-joint system as “a stretched rubber band (the bolt) clamping a sponge (the clamped part)”. The heart of this part is to reveal a key question: why, when a part’s surface is crushed just a little bit, does the whole bolted joint face the risk of complete failure? ...
