20.500.12556/RUL-136395 Thermal mechanical coupling analysis of a flexible spoke non-pneumatic tire Termomehanska analiza nepnevmatskega kolesa z upogljivimi naperami A new type of non-pneumatic tire with a flexible spoke structure is proposed to solve traditional pneumatic tire defects, such as easy bursting, the requirement of real-time maintenance to keep tire pressure, and a complex manufacturing process. The thermal mechanical coupling characteristics of the flexible spoke non-pneumatic tire are studied in detail to obtain the steady-state temperature field distribution pattern under different operating conditions. A unit configuration method is proposed to build the 3D model of the flexible spoke non-pneumatic tire. Then, the thermal-mechanical sequential coupling method is used to analyse the deformation, energy loss and heat conduction of the flexible spoke non-pneumatic tire. Finally, the steady-state temperature field distribution pattern under thermal-mechanical coupling is obtained. The results show that the high temperature region of the non-pneumatic tire is mainly distributed in the middle bending part of the flexible spoke unit, and the temperature gradually decreases from the centre of the flexible spoke to the surrounding parts. The influence of load on the temperature change of non-pneumatic tire is greater than that of the driving speed. This study provides a theoretical basis and method guidance for solving the failure problem of the non-pneumatic tires under the action of thermal-mechanical coupling. non-pneumatic tires flexible spoke structure unit configuration method thermal mechanical coupling temperature field nepnevmatska kolesa upogljive napere metoda konfiguracije enot preizkus prototipa numerična analiza termomehanska sklopitev temperaturno polje true false true Angleški jezik Slovenski jezik Članek v reviji 2022-04-28 13:38:03 2022-04-28 13:38:05 2022-09-15 04:13:50 0000-00-00 00:00:00 2022 0 0 Str. 143-154 no. 3 Vol. 68 Mar. 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2022-03-01 536:519.62 0039-2480 10.5545/sv-jme.2021.7401 105624067 Thermal_Mechanical_Coupling_Analysis_of_a_Flexible_Spoke_Non-pneumatic_Tire.pdf Thermal_Mechanical_Coupling_Analysis_of_a_Flexible_Spoke_Non-pneumatic_Tire.pdf 1 3077D205E25873048A700DA927E7ED2C 9d62a79ed5db45ebf953e5c614fa2fd8b32b4157dcc7d76b9c529805573c87ef fce55fec-c6e7-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=156019 https://www.sv-jme.eu/sl/article/thermal-mechanical-coupling-analysis-of-a-flexible-spoke-non-pneumatic-tire/ 1 97f99d55-c6e7-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=156018 Fakulteta za strojništvo Strojniški vestnik 0 0 0
