20.500.12556/RUL-137283 Optimization of tuned mass damper location for enhanced chatter suppression in thin-wall milling Optimizacija mesta pritrditve masnih blažilnikov za boljše omejevanje drdranja pri tankostenskem rezkanju In this paper, a method to optimize the location of tuned mass damper (TMD) for enhancing chatter stability limits of thin-walled workpiece by using numerical techniques is proposed with due consideration to mass effect of TMD. The dominant mode of workpiece is identified from the simulated and measured frequency response functions of the workpiece. Two TMDs each having single degree of freedom are designed and a finite element model to predict the response of the workpiece-damper system is developed. The effect of damper location on the chatter stability of the thin-walled workpiece is investigated. Further, the locations for TMDs are optimized for enhanced chatter stability of workpiece by using response surface methodology. Milling tests were performed on workpiece with and without TMDs. A three-fold improvement in minimum stable depth of cut is realized after incorporating the TMDs at their optimal locations on thin-walled workpiece. chatter thin-wall milling tuned mass dampers optimization response surface drdranje tankostensko rezkanje masni blažilniki optimizacija metoda odzivnih površin true false true Angleški jezik Slovenski jezik Članek v reviji 2022-06-09 11:55:16 2022-06-09 11:55:18 2022-09-15 04:14:54 0000-00-00 00:00:00 2022 0 0 Str. 339-349 no. 5 Vol. 68 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2022-01-01 621.937 0039-2480 10.5545/sv-jme.2022.4 111032323 Selvakumar_..._Optimization_of_Tuned_Mass_Damper_Location_for_Enhanced_Chatter_Suppression_in_Thin-wall_Milling.pdf Selvakumar_..._Optimization_of_Tuned_Mass_Damper_Location_for_Enhanced_Chatter_Suppression_in_Thin-wall_Milling.pdf 1 5A28195CAA6E0E7FBC3E624BF1751029 ce71916929d5285b4fab1526c9e410332d2fda3e7656a524056f3e83d4712937 65ad3a21-e7da-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=157193 https://www.sv-jme.eu/sl/article/optimization-of-tuned-mass-damper-location-for-enhanced-chatter-suppression-in-thin-wall-milling/ 1 1cb50449-e7da-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=157192 Fakulteta za strojništvo 0 0 0
