Due to the fixing points in vibrating machines being different, adapters are used for each space instrument. In random environments the load is defined as stochastic data. Only linear analysis can be used. This article describes the method for FE modeling of nonlinear contact transient analysis. The load is defined as random stochastic data depicted as a graph versus time and applied to space instruments. For base excitation, the large-mass method was used. The contact is formed by GAP elements. From the results, the PSD (Power Spectral Density) spectrum and gRMS values of vibration are computed and evaluated."@en . "Praha" . . . "2011-05-09+02:00"^^ .
