Calculation of Screws According to VDI 2230, Edition 2003

With this program you can carry out predimensioning of the nominal screw diameter (extended version only) as well as the system calculation of cylindrical screw-in joints according to VDI 2230, sheet 1, edition of 2003.

The whole calculation process involving force and deformation relations is based on the screw-in joint

model. I.e. all dimensions and loads influencing the complete junction from the outside are to be reduced to a screw-in joint and are presumed as known.

You can calculate multiscrew joints, such as e.g. circular ring joint flanges. At that, you must take into account, that the angular momentum applied to the perimeter has been considered using the number of screws on the pitch circle and the resultant loads have been considered for each screw separately. In addition, you can take into account centric and eccentric tightenings/loadings.

Besides, this calculation program has at its disposal technology files which enable you to read screw dimensions, different strength classes and materials of tightened parts directly into the entry page. All data base tables can be customized to the user (e.g. other standards).

Extreme working loads, e.g. corrosion or impact loads can not be taken into account. Calculation Base

The calculation base of the module Calculation of Screws is founded on VDI 2230, sheet 1, edition of February 2003 "Systematische Berechnung hochbeanspruchter Schraubenverbindungen Zylindrische Einschraubenverbindungen" (System Calculation of High-loaded Screw Joints, Cylindrical Single-screw joints).

The fixed tightening force FM of the screw is considered at that as the main selection criterion of the nominal screw diameter.

The following DIN standards have been used, too: - DIN EN ISO 4017 - DIN EN ISO 8676

- DIN EN ISO 4014 - DIN EN ISO 8765
