Selection of the combat vehicle individual wheel drive operation modes under required mobility criteria

Abstract

Abstract With the development of the electric drive systems and vehicle on-board power sources the development of the combat vehicles with individually driven wheels is becoming a promising area. In the presented article, the authors illustrate an approach to selection of the requirements for power plants of such vehicles by an example of an 8x8 combat vehicle with full weight of 25 t. The approach is based on the use of the real-time driving simulator allowing the operator to drive the vehicle along typical routes and gather statistical data on the operation modes of the electric motors in the conditions close to the real operation conditions. The virtual driving for this purpose is performed along the routes which are generated from the known statistical data on the excitation inputs during the vehicle motion. The collected data can be used for the selection of the electric motor mechanical characteristics providing given mobility criteria of the vehicle and for the statement of the requirements for new electric motor specifications which would provide its most effective use on the vehicles being developed.
