20.500.12556/RUL-135445 Nonlinear coupled dynamic modelling of driver-seat-cab system and biomechanical behaviour prediction Nelinearen sklopljeni dinamični model sistema voznik-sedežkabina in napoved biomehanskega vedenja The biomechanical responses of the driver-truck system in a dynamic environment have become a significant concern in the design and control of trucks. When evaluating the riding comfort of the seat-cab system, it is necessary to predict the biomechanical responses of the driver’s different parts and directions. However, there is no reliable model and method for effectively predicting the response characteristics of the driver-seat-cab system. Aiming at such problem, firstly, based on the 7 DOF (degree-of-freedom) seated human biodynamic model established previously, a 10 DOF non-linear dynamic model of the driver-seat-cab system was created, and its vibration differential equations were established. Secondly, the vibration signals for simulation and verification were collected through the road test using a truck. Thirdly, based on the Newmark-β integration method, the specific solution process of the model was given. The non-linear damping coefficients of the front and rear dampers for the cab suspensions were measured with a bench test. Moreover, the simulations were conducted based on the measured model parameters, taking the collected frame vibration signals as the inputs. The results show that the simulation results agree with the test results, proving that the dynamic model can effectively predict the driver’s biomechanical responses. Finally, some useful conclusions were obtained through the simulation analysis. The established model and conclusions can provide technical support for comfort evaluation, optimization design, and control of the seat-cab suspension system. driver-seat-cab system driver’s health dynamic modeling biomechanical responses avtomobilska tehnika kakovost vožnje sistem voznik-sedež-kabina voznikovo zdravje dinamično modeliranje biomehanski odziv true false true Angleški jezik Slovenski jezik Članek v reviji 2022-03-15 11:31:41 2022-03-15 11:31:46 2023-01-05 09:12:56 0000-00-00 00:00:00 2022 0 0 Str. 90-100 no. 2 Vol. 68 Feb. 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 531.395:004.94 0039-2480 10.5545/sv-jme.2021.7429 100940035 RAZ_Zhao_Leilei_2022.pdf RAZ_Zhao_Leilei_2022.pdf 1 02BA016273E3AA6E6A7D2DE88658980E 9b5bece7b91b9f6a4b2637570da17e114b410d77a69c880459d6d300f7aeb816 76857470-a44b-11ec-8556-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=154529 https://www.sv-jme.eu/sl/article/nonlinear-coupled-dynamic-modelling-of-driver-seat-cab-system-and-biomechanical-behaviors-prediction/ 1 1d1ce345-a44b-11ec-8556-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=154528 Fakulteta za strojništvo Strojniški vestnik 0 0 0
