Effect of tire dynamic characteristics on vibration load at the operator’s workplace

Abstract

The article addresses a current issue – reducing the vibration load at the operator’s workplace in the utility machine with respect to the use of chassis elements as vibroprotection element. The results of studies aimed at determining the effect of tires dynamic characteristics on the vibration load of the operator’s workplace are presented. A computational scheme designed to conduct experimental research has been shown. Correlation between tire rigidity and air pressure in the tire, as well as correlation between tire service life and tire pressure have been revealed. Results of studies aimed at determining relations between the dynamics of mean-square values of vibration acceleration of the frame, the floor and the operator’s seat, and the rigidity coefficients of utility machine tires. Conclusions have been made as to the relevance of using chassis elements as vibroprotection element at the operator’s workplace in the utility machine.
