مقدمه

Vibrations during driving represent a common concern in ergonomic evaluations of driver conditions. However, how alterations in the mechanical characteristics of the car and driver's seat might impact vibrations on different body parts is a crucial inquiry. Considering that vibrations affect various body points uniquely, can these changes be predicted before construction? This question is addressed through mannequin simulation in this paper.

مواد و روش‌ها

Mr. Liang and Mr. Chang introduced a vibrational model of the driver in 2007, which has been the most authenticated model to date. The dimensions of the utilized mannequin were related to the height of Iranian male percentile 50, and other dimensions were extracted proportionately. Two different values of seat springiness and damping were modeled. SimWise software was employed to assess vibration alterations.

یافته‌ها

The outcomes demonstrated that reducing the overall seat springiness reduced the vibrational range in the abdomen and thighs but increased vibrations in the head, pelvis, and torso.

نتیجه‌گیری

This study solely aimed to evaluate the possibility of simulating forced body vibrations concerning changes in mechanical specifications of the seat and car, confirming this feasibility. Certainly, providing mechanical specifications for the seat and car requires examining more mannequins and their mechanical features, which this current study is unable to address.
