The presented paper deals with a design and generation of a program for calculation of stiffness and shear stress of forcing springs. The given calculation program was generated in the program of Microsoft Office through the Excel application by means of defined sequences of the individual orders. The calculation program serves for calculation of stiffness of cylindrical and conic helical forcing springs with circular and rectangular section of wire. The designed program calculates shear stress and stiffness of the spring after entering parameter values inevitable for calculation. The program contains also a database of the standardized springs which after selection of the standardized spring assures inserting of corresponding values by means of which the program prevents a user from incorrect defining of the standardized data.
