Vibration Analyses of a Single Osteoblast in Vitro Using the Finite Element Method

摘要

In this study, the dynamic properties of a cell in vitro are analyzed using the finite element (FE) model. An idealized FE model of a bone cell is developed, and then FE analysis is performed to study its vibration in vitro. The first ten natural frequencies of the bone cell can be obtained using the FE method, which are 11.35 Hz, 11.39 Hz, 15.51 Hz, 23.38 Hz, 25.64 Hz, 25.71 Hz, 30.82 Hz, 30.89 Hz, 35.27 Hz and 35.34 Hz, respectively. The mode shapes of the first ten modes are presented as well. In addition, the frequencies of 1-80 Hz and acceleration of 0.5 g (9.8m/s~2) of base vibration have been applied to the harmonic vibration analyses. The relationship of displacement versus frequency is plotted based on the responses for the harmonic vibration. This study will help us further understand the in vitro vibration characteristic of a cell.
