An investigation of the influence of selected structural parameters of a machine frame on its static and dynamic properties has been presented. Comparative calculations of frames in a static area were accomplished in order to perform comparison with experimental results presented in work (Iżykowski et al., 1994). Dynamic calculations of hypothetical machine frames were performed in order to examine effects of selected constructional parameters on their dynamic properties. Their influence on natural frequencies and vibration modes was investigated. The calculations were performed for various thickness of a frame flange, various initial forces in pre-stressed bolts, using or not stiffening ribs. Next, several models of a frame attachment to foundation were tested to find less sophisticated FE model of the tested system for further dynamic calculations. In the last stage, an influence of application of a special layer made of a damping material to frame walls on natural frequencies and modal damping factors of a machine frame was investigated.
