Abstract: The human body, as a complex
biomechanical system, is daily exposed
to oscillatory movements. Vibrations are observed
as small displacements of points compared
to the dimensions of the system.
The body's sensitivity to vibration depends on many factors,
such as body position, muscle tension, frequency,
amplitude, and direction of vibration.
Comfort is one of the important factors in the study
of the quality of the vehicle.
Exposure to vibrations over a long time can seriously
and permanently damage some organs of the body.
In this paper, the influence of vibrations on the lumbar part
of the human body was investigated.
Vibrations were determined experimentally while the vehicle
was moving on the highway for the case of two different speeds.
A 3D computer model of a lumbar spine was developed using CT scans.
The acceleration values obtained by the experiment
were the input values for the numerical analysis
of the lumbar spine using the Ansys software package.
Keywords: Vibration, measurements, lumbar
spine, numerical analysis
