Fatigue Strength Assesment of Vibration Transorter’s Motor Carrier

Abstract

Theoretical basics formulation of the implicit Newmark-method for numerical integration of dynamic motion equations is presented in the first part of this paper. According to theoretical assumptions, algorithms for the integration of dynamic motion equation are developed. Algorithms are implemented into the software package P AK. The second part oft he paper shows the process of modeling the motor carrier, as well as the results of the analysis. Based on the results, the analysis and assessment of fatigue strength in the prescribed conditions of exploitation was carried out. Dynamic analysis of the motor carrier in the steady-state oscillation mode showed that the motor carrier has an unlimited working life.
