Abstract
This article examines the design features of mining dump trucks and the issues of optimizing their operational parameters. Mathematical modeling of vibration processes arising during dump truck movement over uneven roads and due to the shift of the cargo center of gravity has been carried out. Based on Lagrange equations, the vibration frequency, amplitude, and phase were determined, and the effect of load distribution between the front and rear wheels was analyzed. The research results make it possible to assess the mechanical stresses in the dump truck frame and main components, determine their strength limits, and improve stability when operating on uneven roads. The findings contribute to reducing additional fuel consumption and extending the service life of the units.
