| With the energy and the environment crisis is increasingly obvious, the "energy-saving and emission reduction" requirement is put forward in the plan of Twelfth Five-Year. New energy vehicle is focused in the automotive industry. Electric automobile industry undoubtedly has been great expectations by the industry and the automotive market, therefore the study of the low-speed electric vehicle sweeper has important significance.The paper is based on the electric cleaning vehicle, as the research object, the overall design scheme is put forwarded according to the working characteristics of the electric sweeper. Based on the overall design plan, first of all, the vehicle shape drawing is completed by CATIA software according to the size of the main parts of it. Secondly, drive arrangement of sweeping vehicle driving system is ensured, the walk parameters matching of power system is completed. Finally, a new type of "π" cleaning devices is designed. In the driving power system of electric sweeper:first of all, cleaning system for hydraulic control system is completed, hydraulic schematic drawing and the parameters and models of the main components are finished and ensured; Secondly, according to the working characteristics of electric sweeper, the simulation models of motor fuzzy controller, driving system and so on are designed in the MATLAB/Simulink, in the MATLAB environment cleaning condition and two speed transmission are designed to meet the characteristics of work. Finally, the operating system model is embedded to Advisor to develop, and performance simulation and analysis of the electric sweeper under the conditions of clean and constant speed are finished, to research the Influence of vehicle performance simulation in has and no custom models and different working conditions. |
