Abstract:

The article presents the mathematical simulations of dump truck linear motion along a straight road segment as a motion of multimass system with eight degrees of freedom.

Purpose. To analyze the results of the study of dump truck dynamic and traction-speed performance in the course of motion.

Methodology. General scientific and special study methods, including scientific generalization, methods of integrated assessment of technical level, mathematical modeling and linear programming were used. To solve the problem we have formulated differential equations of motion, using the Lagrange equations of the second kind and the corresponding expressions of kinetic and potential energy as well as dissipative function.

Findings. By mathematical calculations in the Wolfram Mathematica software, the traction and dynamic characteristics calculation method for the dump truck moving along the road with longitude inclination was received.

Originality. A planar and spatial design diagrams and motion equations of the vehicle in the course of straight-line motion were made, considering elastic and dissipative characteristics of elastic constraints, longitudinal slope and road profile, changes of design characteristics which can provide a near real picture of motion dynamics.

Practical value. The method of calculation of the dump truck dynamic characteristics in motion has been developed. Based on the analysis of the dump truck design parameters presented, one may provide recommendations on reduction in capital expenditure for development of a quarry.
