| Summary: | Ecological, economic and transport problems of cities prompt humanity to search for new vehicles and ways of organizing
urban transportation. Today, the use of electric vehicles in developed countries is gradually increasing. Production and sale of
electric vehicles are relevant. There is a potential demand for such products from consumers. The disposal of existing vehicles
equipped with ICE given their large number creates a significant social problem. One way to solve it is to convert them into
hybrid and electric cars. Very often, such re-equipment is carried out by the owners of old cars with internal combustion
engines, while no studies are carried out on its feasibility. The lack of methods for calculating the operational properties of
converted vehicles complicates this process.
The development of a methodology for compiling a mathematical model of a power plant and the movement of a converted
vehicle of categories M1 and N1 is an urgent task. With the help of which it would be possible to determine its operational
performance. To develop a methodology for compiling a mathematical model of electric vehicle motion, a layout design of a
front-wheel drive car was selected. As applied to the mechanical system of an electric vehicle with one degree of freedom, the
equation of motion in generalized coordinates, the Lagrange equations, is used for the mathematical description of dynamic
processes. To determine the generalized force, it is necessary to determine the elementary work of all the forces and moments
acting on the car during its movement. As a generalized coordinate in the electric drive, the angular displacement of the motor
shaft is accepted, to which the parameters of all the mechanical links of the system are given. Equations of electric vehicle
motion corresponding to its mechanical design is obtained. |
