摘要：
In this paper the theoretical and numerical studies on transversal vibrations of partially tensioned column are presented. The discussed structure corresponds to the screw drive system which is used in cranes. The formulated boundary problem allows one to calculate the vibration frequency. In this manuscript only an influence of the rotational stiffness of the support on linear component of vibration frequency is discussed. Moreover the differential equation and boundary condition are given to present the behavior of the structure at linear vibrations. The results of numerical simulations are concern on linear component of vibrations in relation to the location of external load application and different rotational stiffness of the support.
