The paper presents the possibilities of using vibroacoustic methods in the study of the technical condition of designed multimedia mobile scenes. In particular, the possibility of implementing modal analysis methods in modelling and diagnostic research process has been presented. The use of virtual methods enables diagnostic tests both at the design stage and at the stage of normal operation, whereas modal methods help to explain the nature of the work of the element under investigation.
The construction of the mobile stage is a huge challenge for designers due to a very wide range of variable factors affecting it, such as wind or temperature, the value of which in this case depends on the geographical location. An inherent element of the influence of these factors are the accompanying various, both constant and variable loads. Detailed identification of these loads is extremely important both for the safety of use and the diagnostic possibilities of such a complex mechanical structure.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
