Abstract
Introduction. The article is devoted to the study and optimization of the chassis parameters of an electric cargo vehicle, depending on road conditions in the process of performing the transport task of an agricultural enterprise, using the method of simulation modeling.
Object: study of a digital twin of the suspension of a sample vehicle to optimize its technical characteristics.
Methods. Based on the developed mathematical model of the suspension of an electric vehicle and its calculated characteristics, a simulation model of the chassis of an electric cargo vehicle was compiled. The simulation model contains parameters of road surface roughness, as well as the specified speed and longitudinal acceleration of the digital twin. The objects of research were the elastic-damping characteristics of the suspension elements of an electric vehicle.
Results. The results of simulation tests of a digital twin of an electric vehicle chassis when passing an obstacle in the form of a 50 mm hole are presented, and the case of maximum acceleration of an electric vehicle from a standstill of 3 m/s2 is also considered. The result of the simulation was the dependence of the movement of the body along the vertical axis z ̇ (m/s) and the rate of change in the angle of inclination of the body in the longitudinal plane (swaying of the body) θ ̇ (rad/s), on the time of passing the obstacle. The analysis of the operation of the suspension of an electric vehicle substantiated the characteristics obtained by calculation. The suspension of an electric vehicle allows for smooth operation in the range of 1.5-2.5 Hz.
