20.500.12556/RUL-134770 The influence of radial slots on dynamic stability of thermally stressed circular saw blade Utjecaj radijalnih utora na dinamičku stabilnost termički napregnutog lista kružne pile The influence of temperature distribution, temperature difference between the rim and centre of the saw blade and the number and size of radial slots on the dynamic stability of the circular saw blade was analysed in this work. The optimum number and size of radial slots for a circular saw blade with a diameter of 300 mm and a thickness of 2.18 mm is determined according to the least favourable temperature distribution and temperature difference. The critical rotational speed and lateral stiffness at the rim of the saw blade are considered as criteria for dynamic stability. According to the mentioned criteria, it was found that the optimum number and length of radial slots is 6 and 30 mm, respectively. In some cases, longer radial slots would further increase the critical rotational speed, but would also greatly decrease the lateral stiffness of the saw blade. circular saw blade finite element method radial slots critical rotational speed temperature distribution krožni žagni list metoda končnih elementov dilatacijske zareze kritična vrtilna hitrost porazdelitev temperature true false true Angleški jezik Hrvaški jezik Članek v reviji 2022-02-01 08:34:15 2022-02-01 08:34:18 2022-09-14 04:09:48 0000-00-00 00:00:00 2017 0 0 Str. 341-349 no. 4 Vol. 68 2017 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 630*822.331.5 0012-6772 2858377 RAZ_Merhar_Miran_2017.pdf RAZ_Merhar_Miran_2017.pdf 1 3F84502667C79D6AF8D3EFA0B8AA327D 1e903d58937d4e727ea726ae4cb516950de9835ca9431e6c685f443b44657138 fa41af85-8331-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=153399 https://hrcak.srce.hr/index.php?show=clanak&id_clanak_jezik=283077 1 2ea3b101-8331-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=153398 Biotehniška fakulteta 0 0 0
