Schraubendiagramm bolted joint diagrammit Vorspannung Schraubenberechnung
This tutorial is about bolted joint diagram. The bolts and the boards will be regarded as a spring. Each componet is regarded as a spring. For springs will be used the hookes law, which will be represented by a straight line. We have here two different things: We have got here a bolt and we have got plates. Therefore we need here two straight lines.
This straight line represents the bolt. And this one represents the plates. Here we have got cs. It is the gradient of this straight line (bolt). This cp is the gradient of this straight line (plates). In general, this is the formula for hookes law. It follows that c=F(force)f(deformation) This is the gradient of the straight line by Hooke's law. The deformation is depicted on the xaxis.
The associated force is depicted on the yaxis. Note: The force is directly proportional to deformation. The deformation of the bolt is read off from left to right. The deformation of the place is read off from right to left. If we do not tighten a bolt, then there will be no force, which is applied to the bolted joint. That means the force F=0 . And there is no deformation. If we tighten the bolt slightly, then the force will become greater. Here we can get the associated deformation.
The bolt becomes longer (extension). Concurrently, the plates are getting shorter (compression). We have got here this force. And so we have got the deformation of the plates. If we continue to tighten the bolt, then we will get eventually the bolt pretensioning force Fv. That means: The bolt is extended by fs and the plates become shorter by fp. This is the assembly state of the bolted joint. Now an additional force will apply on the bolted joint.
This force is called: maximum operational axial force FB loading the connection. This force is caused by operating conditions like oil pressure in hydraulic cylinder. For example, if you know the pressure and the area, then you can calculate the operational force FB. This force tries to destroy the connection. Here you can see the assembly state. If you load the connection by the force FB, the bolt will be stretched further by an amount fB. Here is the maximum operational axial force FB.
Below the force FB there is the clamping force FKL. Force FB and FKL are output values for the calculation. The force FKL is often given. You want that the oil container remains tight. Therefore you need a certain minimal clamping force FKL. FB and FKL are output values, with which you can calculate all other forces. You should also know, the force FB consists of two parts. This is the maximum operational axial force FB.
