Abstract: While driving a car, the comfort of the driver is crucial. By considering seated concerns for the drivers' comfort and health, the exceptional and skilled designers' concept should be successful. On a standard car seat, the bottom and upper body sections, in addition to the head support, are significant. The seat's vibration-attenuation design is crucial to the comfort of the driver. Components of the human body are sensitive to lower frequency vibration, and problems occur when they are frequently subjected to it. An individual's health will be harmed by prolonged vibration exposure. In this work, the finite element method with experimental modal analysis has been used to estimate and evaluate the natural frequencies in the driver's seat which affect to the human body. Since it has been shown that some of these frequencies coincide with the ones that are dependent on the human body, the natural frequencies associated with a driving seat that affect the human body can be changed without modifying the design.

Keywords: dynamic analysis; natural frequency; whole body vibrations; WBV; finite element analysis; FEA.
