摘要

Electronic-hydraulic driving vehicle has the advantages of high energy-utilization efficiency, excellent driving power, fine cross-country performance, and outstanding controllability, which make it a research focus in the field of novel transmission technique. Experimental platform is an important and essential instrument for the research and development of electronic-hydraulic driving vehicle, and its optimal design was conducted based on the multi-factor synthetic evaluation model. Three electronic-hydraulic driving modes were investigated in this study, which included the series type, the parallel type, and the mixed type. The investigated parameters in the multi-factor synthetic evaluation model consisted of volume, mass, system noise, requirement of spatial layout, difficulty in structure array, transformation cost of present car, transmission of gear-box, infinitely variable speed, mechanical transmission mode, difficulty in control, controllability of the driving system, total efficiency of the transmission system, energy integrated management strategy, loss of system energy, energy recovery efficiency, dynamic performance, security, reliability, probability, applicability, and so on. The weight and score of each parameter in the multi-factor synthetic evaluation model had been obtained by the expert scoring system. In order to satisfy the special demand of the military vehicle, it could be found that the series electronic-hydraulic driving mode was the optimal option, which could be judged from the final scores of the three modes according to the multi-factor synthetic evaluation model. Design and construction of the experimental platform would be propitious to advance the further research of the electronic-hydraulic driving vehicle and promote its application in the field of novel transmission vehicle.
