On using a hybrid power plant on military tracked and wheeled vehicles

Abstract

One of the areas for improving military tracked and wheeled vehicles is considered, nmely the use a hybrid power plant. A problem is determining the effectiveness of using a hybrid power plant in military vehicles. An analysis of foreign samples the military tracked and wheeled vehicles with an integrated hybrid power plant and their technical characteristics is carried out. A selection of traction electrical equipment for the construction a hybrid power plant for a tank and an armored personnel carrier was made. The technical characteristics of traction electric motors are considered: SUMO HD HV3500-9P company DANA (Canada), EMRAX 348 company Enstroj (Slovenia); traction Li-ion battery company WB Electronic (Poland), SUMO HP HV900-3P motor generator (LSG130 generator) DANA company (Canada). A study was done on the composing а components of the hybrid power plant in engine and transmission compartment and the hull of the T-72 tank, BMT-72 heavy infantry fighting vehicle and BTR-4MV1 armored personnel carrier. The study was conducted by modeling and comparative analysis. The simulation was carried out in a computer-aided design system Creo Parametric 2.0. As a result of the study, the technical characteristics of the BMT-72 and BTR-4MV1 products were determined with the introduction of a hybrid power plant on them. It was found that the use of a hybrid power plant on the BMT-72 product did not lead to improvement in speed characteristics and increase the power reserve, in addition to ensuring movement on traction batteries up to21 kmon a dry dirt road. The use of a hybrid power plant on armored personnel carrier BTR-4MV1 improves its maneuverability when applying a power transmission scheme from a traction motor to each wheel separately, provides movement on traction batteries up to53 kmon a dry dirt road. The total power reserve will be no less than the base product, since the capacity of the fuel system did not decrease. The estimated maximum speed of an armored personnel carrier with a hybrid power plant corresponds to the maximum speed of the base product and is110 km/h. The introduction a hybrid power plant on military tracked vehicles weighing 40-50 tons is not advisable due to insufficient electric power, large overall dimensions a traction batteries and large mass of the product. A promising direction is the introduction a hybrid power plant on military wheeled vehicles weighing up to 30 tons. To implement a hybrid power plant on armored personnel carrier according to the scheme of transferring power from the traction electric motor to the wheel, it is necessary to develop a gearbox design with two gears.
