Bone cells are deformed according to mechanical stimulation they receive and their mechanical characteristics.
However, how osteoblasts are affected by mechanical vibration frequency and acceleration amplitude remains unclear.
By developing 3D osteoblast finite element (FE) models, this study investigated the effect of cell shapes on vibration characteristics and effect of acceleration (vibration intensity) on vibrational responses of cultured osteoblasts.
Firstly, the developed FE models predicted natural frequencies of osteoblasts within 6.85–48.69 Hz.
Then, three different levels of acceleration of base excitation were selected (0.5, 1, and 2 g) to simulate vibrational responses, and acceleration of base excitation was found to have no influence on natural frequencies of osteoblasts.
However, vibration response values of displacement, stress, and strain increased with the increase of acceleration.
Finally, stress and stress distributions of osteoblast models under 0.5 g acceleration in Z-direction were investigated further.
It was revealed that resonance frequencies can be a monotonic function of cell height or bottom area when cell volumes and material properties were assumed as constants.
These findings will be useful in understanding how forces are transferred and influence osteoblast mechanical responses during vibrations and in providing guidance for cell culture and external vibration loading in experimental and clinical osteogenesis studies.
