Nowadays it is essential to ensure comfort as well as health friendly ride due to progressive demands of spending time in vehicle. All vehicle owners face the wheel balancing issue and thus this problem is very especial for most of the consumers. Various references were analysed in master thesis; moreover, the wheel balancing, impact on vehicle vibrations was examined. AUDI A4 was chosen to conduct the research. Measurements were carried out in various positions of the car. Vibrations in positions such as the floor of the car, the seat, the backrest, the steering wheel and the trunk have been measured by changing speed and wheel imbalance. The research was conducted using two types of tires. Additional weights were affixed in order to activate wheel imbalance. The weight ranged from 25 g to 80 g. Measurements were carried out using vibration meter SVAN 958. According to indicated results the values of vibration are higher while driving with summer tires. In all cases the highest vibration was indicated at the backrest of the seat. It is also visible that the car vibration significantly increases by reaching 100 km/h. Calculation was made to assess the exposure of the daily vibration while running 1,2 or 4 hours. The complete calculations featured that the vibration in the car which has influence on hands is significantly lower it is permissible. |
