Loading of the Musculoskeletal System of a Person While Driving in a Passenger Car

Abstract

The damping of these dynamic effects is solved by the vehicle suspension system. All this is then reflected in the safety of driving, the driving characteristics of the vehicle, but also in the response to the locomotive apparatus of the vehicle crew. Cervical injuries are usually caused by the inertia of the head. Although the product of speed and weight (kinetic energy) are proportional to the values that increase the likelihood of neck or head injury. It is surprising that significantly more injuries occur at slow speeds. The force effects transmitted to the cockpit always affect the body of the person controlling the vehicle. In the long term, one-sided loading of the organism negative impact on human health, in rare cases can lead to death. The main aim of the article was to measure the dynamic effects that are transmitted to the driver (co-driver) when driving in a passenger car over obstacles. The measurement was carried out experimentally in a real environment on a designated road at different driving speeds and different distribution of obstacles on the road. Acceleration sizes generated on the driver/co-driver seat structure, under the buttocks, head and cervical vertebrae C7 were sensed by acceleration sensors. The result of the work was to find out how much dynamic effects are transmitted from the vehicle structure to the driver/co-driver body, respectively. the head and vertebra of the cervical spine C7 (vertebrae cervicales) as the vehicle crosses obstacles.
