Drgania maszyn o korpusach odkształcalnych podpartych elastycznie na podatnej konstrukcji

The paper presents the method of determining the vibrations of a system composed of the machine with deformable body supported on a flexible structure by means of a set of elastic and damping elements. On the grounds of the equations obtained it is possible to calculate the vibrations of both the machine and of the supporting structure before the machine is mounted on its place of work. The sources of these vibrations are arbitrary periodic forces which arise due to the motion of the machine. In order to solve the equations, the programme for a digital computer was prepared. The method of determining the dynamic characteristics of the machine, considered to be free in the space, was also elaborated. The paper also includes the experimental verification of the formulae derived.
