Computer simulation possibilities of dynamic tests of large-scaled mechanical structures

Abstract

Abstract The work is devoted to the analysis of the computer simulation capabilities of dynamic testing of large-scaled structures when exposed to acoustic noise, sinusoidal and random vibration, linear acceleration, mechanical single and multiple shocks. The simulation results obtained with regard to the regulatory requirements for the test methods for the action of external influencing factors reflect the effect of the main conceptual and technical solutions of the structures on their dynamic behaviour. Computer simulation of dynamic tests allows, on the one hand, to exclude unacceptable dynamic effects due to unsuccessful design decisions, on the other hand, can be considered as an important part of the design conformity assessment with technical requirements.
