Opis:: The results of theoretical and numerical research into free vibrations of column subjected to the follower force directed towards the positive pole locally resting on Winkler elastic foundation were presented in this work. Differential equations of motion and boundary conditions of considered system were determined taking into account total mechanical energy and Hamilton’s principle. On the basis of solution of boundary problem, the courses of free vibrations frequency curves as a function of external load were obtained taking into consideration parameters of length and location of Winkler elastic base and also parameters describing loading head geometry.

Opis:: The subject of the results of theoretical and numerical studies measures to designate the effect of pre-stress on the vibration of geometrically non-linear column exposed to the load force directed to the positive pole. Considering the total mechanical energy of the system the equation of motion and the boundary conditions necessary to solve the boundary problem were determined. Based on the kinetic stability criterion the range of values of internal compression forces was determined in which the growth of critical load of the column above the local loss of stability was achieved. In the research the geometrically non-linear system was analysed with variable asymmetry of bending stiffness and at selected values of geometrical parameters of the head realizing the load.
