Abstract

W artykule przedstawiono porównanie przenoszenia drgań oraz impedancji mechanicznej dla pięciu prostych modeli biodynamicznych używanych w procesie projektowania foteli dla pojazdów. Przedstawione modele są używane w obliczeniach w celu ograniczenia czasu badań eksperymentalnych i zbierania danych podczas procesu projektowania produktu. Badania wykazały, że porównywane modele o dwóch, trzech i czterech stopniach swobody dają bardzo dobre wyniki na wstępnym etapie projektowania siedzeń. Analiza wykazała, że dalsze prace są potrzebne do zbadania częstotliwości rezonansowych dla określonych cech budowy anatomicznej oraz różnych cech osobniczych dla populacji pasażerów. 

 

Five biodynamic models are investigated to approximate vertical seat vibration transmissibility and mechanical impedance in an effort to reduce experimental time and data collection when designing vehicle seats. The research has found that these biodynamic models of two, three and four degrees of freedom are ideally suited for initial seat design, since whole body vibrations can be easily depicted at approximately 5Hz. Further research is necessary to investigate the resonant frequencies for defined anatomical structures, passenger variability and the use of a backrest support.
