Abstract
V sklopu magistrske naloge smo razvili sistem, ki avtomatizira izvedbo meritev pri eksperimentalni modalni analizi. Sistem, ki izvaja avtomatizirano vzbujanje in z uporabo brezkontaktne metode izmeri dinamski odziv, smo avtomatizirali z uporabo mikrokrmilnikov in osebnega računalnika. Naloge se lotimo s pregledom različnih vrst nihanja in izpeljavo vodilne enačbe nihanja tanke plošče. Sledi predstavitev mehanskega, strojnega in programskega dela sistema. Na koncu sledi test delovanja sistema. Najprej predstavimo uporabljeno merilno verigo in algoritma za določitev obratovalnih parametrov. Sledijo testne meritve in vizualizacija izmerjenih vrednosti.

Title:Development of an Automated Measurement System for Experimental Modal Analysis
Abstract:
In this master's thesis, we have developed a system aimed at automating the data acquisition for experimental modal analysis. The system which performs automated excitation of analyzed structure and measures dynamic response using non-contact method was automated using micro-controllers and PC. We start the thesis by reviewing different types of vibration and deriving governing equation for thin plate. Following, we represent the hardware and software of used system. In the last part we did system validation on a real case problem. First, we developed an algorithm to determine operation parameters. Which is then followed by test measurements and data visualization.

Keywords:Arduino, automatic data acquisition, non-contact measurement method, thin plate dynamics, experimental modal analysis, stepper motor
