Cylindrical Pin Calculation

Information > 3-D, Further > Cylindrical pin calculation

You use this function to check whether a cylindrical pin that was inserted for the connection of two parts has the required stability to withstand a specific force. The function calculates the shear force in the shear joint, and the required minimum diameter of the pin.

When you call this function, the Cylindrical pin calculation dialogue window will be displayed.

The input fields:

Force (Newton)
Pin diameter and Pin length (mm)

The data can be entered manually or taken over from the drawing. You have the following two options to take over data from the drawing:

Click the symbol and identify the pin in the drawing. Diameter, length and the material (internal) will be taken over into the dialogue window.
Right-click in the input field and select the Pick distance function in the context menu.
Material and Permissible stress in shear joint (Pascal)
Thickness of the two parts ( mm)

The thickness can be entered manually (in mm) or taken over from the graphic. To do this, click the icon and select the part in the drawing. The thickness will be taken over into the dialogue window.

Permissible stress in the upper part and the lower part (Pascal)

Click Calculate to start the calculation.

Calculated are:

the shear force in the shear joint

If the pin passes the test, this will be indicated by a checkmark symbol; if it fails the test, an exclamation mark symbol will be displayed.

the minimum diameter of the pin
