One of the directions of development of weapons and tactics of its application in modern warfare is the use of ground wheeled robots on the battlefield. The results of the analysis of the design of ground robots show that the type of power plant and the structure of the transmission significantly depend on the purpose and weight and dimensions characteristics of the robot. Robots with small dimensions and mass are equipped with an electric drive, which provides them with good running qualities and camouflage properties. Robots with increased dimensions and mass have better tactical and technical characteristics, but also require more powerful power plants. In this case, power plants with an internal combustion engine and an electromechanical transmission are most often used. In this case, the traction characteristics of the machine increase, the combat radius, the duration of autonomous action and cross-country ability increase.
The purpose of the article is to form a method for calculating the traction of a ground wheeled robot with an electromechanical transmission and determine the main indicators of its traction-speed properties. The developed methodology includes a number of sequential stages: determining the required power of the internal combustion engine; determining the parameters of the traction electric motor; determining the gear ratio of the mechanical gearbox; calculating and constructing traction characteristic and dynamic characteristic; determining the acceleration characteristics of the robot. The developed methodology allows you to quickly and with sufficient accuracy determine the characteristics of the power plant and electromechanical transmission of a ground wheeled robot, as well as the values of its traction-speed properties. The methodology can be used both at the design stage of a wheeled robot and for evaluating the traction-speed properties of machines that are proposed by developers for adoption on an initiative basis.
