Simulation model of a transport vehicle with a fixed-ratio transmission and a flywheel energy storage in case of random external action

Abstract

Abstract The purpose of this study is to evaluate the dynamic qualities and efficiency of a heavy-duty transport vehicle equipped with a mechanical transmission, using a combined power plant (CPP) with a flywheel energy storage (FES), establish an acceptable level of power reduction of the main internal combustion engine (ICE), determine the range of installed power of the FES drive and its average value of efficiency, as well as the calculation of the level of required energy capacity of the flywheel when driving in various types of terrain. A universal technique for simulating statistical modeling of external disturbances acting on the transport vehicle has been developed. Using the developed methodology, the vehicles’ characteristics have been compared according to the criterion of average speed and an assessment of the efficiency of the use of CPP has been carried out. The results obtained allow us to carry out a comparative analysis of vehicles equipped with a conventional or combined power plant with a random external action of the road, as well as optimize their parameters.
