Original abstract

Nowadays the vibro-acoustic issues are to the foreground and these questions are often topics in transport engineering. Largely in sphere of automotive, there is daily discussed particularly the passenger safety, car performance and speed, driving comfort which is significantly influenced by vibrations and emitted noise. At first stage, before the harmonic response analysis could be investigated, the modal parameters need to be determined. According of gained modal parameters it is possible to continue in the next stage. In terms to examine the critical places on the structure, experimental measurement and numerical simulation based on the finite element method (FEM) are proposed. This paper primarily includes investigation of operating deflection shape (ODS) and sound pressure level (SPL) on simple structure. Mutual validation of two approaches is required in text below.
