The method presented consists in graphic representation of vibrations of subassemblies in the form of a trace on a plane. It is created by associating instantaneous rms values of vibration acceleration and instantaneous Rice frequency values obtained as a result of short-time signal processing. On the basis of the shape, orientation of the created trajectory and / or dispersion / concentration of points on the Rf – arms plane, the type of non-stationarity of generated vibrations can be identified. The presented methodology can be used for testing machine prototypes. The results in the proposed form can be helpful to determine the type of vibration reduction systems for individual machine subassemblies. It is also possible to detect subassemblies for which an increase in machine capacity results in an increase in the level of generated vibrations. The location of the averaged values of measures obtained for a new machine on the Rf – arms plane can be a reference point for further monitoring of machine vibration and for detection of damage or malfunction of its subassemblies.","PeriodicalId":38508,"journal":{"name":"Vibrations in Physical Systems","volume":"31 1","pages":"2020112-1-2020112-10"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68247343","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The research group consisted of adolescent female football players who underwent standard FMS assessment by a physiotherapist. In order to objectify the physical performance assessment, a mechanical model was proposed, on the basis of which the parameters supporting the evaluation of the test were defined. The example of the analysis of one of the exercises (push-ups) presented in the paper showed that even the players who obtained the highest marks in the test do not always perform the exercises flawlessly, which is a consequence of subjective assessment made by specialists. The use of a motion capture system together with an appropriate biomechanical model allows for a much more objective assessment of the physical performance and detecting any dysfunction of the movement apparatus of the examined persons.","PeriodicalId":38508,"journal":{"name":"Vibrations in Physical Systems","volume":"31 1","pages":"2020220-1-2020220-11"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68248427","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
