Diagnostics of Circular Sawblade Vibration by Displacement Sensors

Abstract: • The paper deals with problems of the circular sawblade vibration. In the introductory part, theoretical bases are summarized to determine the form of vibrations and critical and resonant rotational frequency. A diagnostic method is proposed for the direct measurement of amplitudes of a circular

“…It could be excepted that teeth gap could be considered as a type of slot and has an infl uence on natural frequencies either statics or dynamics. In the past the research based on diff erent types of slots, natural frequencies and critical rotational speed was subject in many scientifi c papers (HolØyen, 1987;Mote, 1965;Nishio and Mauri, 1996;Schajer and Mote, 1983;Yu and Mote, 1987;Svoreň, 2011;Stachiev, 1970;Veselý et al, 2012) In the paper is used the fi nite element method. Its applicationon oscillation and determination of the natural frequencies of circular saw blade was research area of many authors (Gogu, 1988;Leopold and Münz, 1992;Michna and Svoreň, 2007;Ekevad et al, 2009;Droba, Paulíny and Svoreň, 2013).…”

“…Many scientists dealt with experimental methods of circular saw blade oscillation (Mote, 1965;Pahlitzsch and Rowinski, 1966;Stakhiev, 1970Stakhiev, , 1998 Veselý et al, 2012). Some authors studied the application of the fi nite element method using different software programs to determine the oscillation of saw blade (Gogu, 1988;Holyen, 1987, Leopold andMünz, 1992;Michna and Svoreň, 2007;Ekevad et al, 2009).…”

“…Jednakże z powodu częstych błędów obliczeniowych, a przede wszystkim trudności z uwzględnieniem w modelu operacji napręża-nia brzeszczotu, bardziej powszechne wydaje się wyznaczanie ich eksperymentalnie [1,6,9,11,14,15]. Wśród metod empirycznych najbardziej wiarygodna, lecz bardzo żmudna, jest metoda wykorzystująca test harmoniczny [1,3,8,11,14].…”

“…Wśród metod empirycznych najbardziej wiarygodna, lecz bardzo żmudna, jest metoda wykorzystująca test harmoniczny [1,3,8,11,14]. Znacznie wydajniejsza i dająca dobre efekty w przypadku pił o prostej konstrukcji jest metoda, w której wykorzystuje się test impulsowy [7,15]. Do pomiaru przemieszczeń piły spowodowanych wymuszeniem impulsowym można w niej wykorzystać czujnik indukcyjny [7,15] lub dobrej klasy mikrofon pomiarowy, albo zastosować metodę wizyjną [7,9].…”
