文档介绍：摘要
近几年来,随着人们生活水平的提高和环保意识的增强。节能环保的新型动力引起了人们的关注,也是现代工程机械发展的趋势,它在全世界都有着广泛的应用前景。原有的摊铺机、挖掘机等工程机械的动力系统均为发动机,然而噪音大、废气污染环境等已经是不可忽视的问题。本设计就是针对此问题提出的用电动机替代发动机做为工程机械的动力源。通过分析典型工程机械比如摊铺机、挖掘机等工作特点,在此基础上,进行电驱工程机械实验平台液压系统的设计。电驱工程机械试验平台通过电涡流测功仪的加载模拟摊铺机、挖掘机等工程机械的工作特点,以测试该液压系统的性能。

Abstract
In the past few years, with the improvement of people’s living standard and the enhancement of awareness of environmental protection, people pay more and more attention to the new-type motive power with energy conservation and environment protection, which is the developmental trend of modern construction and machinery, and owns a wide prospect of application. The driving systems of constructive machinery, like paving machine, excavator are all motors, which are always arising serious noise and heavy air pollution. This design of paper focuses on the replacement of motor with electric motor. Based on the analysis of operating characters of the classic construction machinery, like paving machine, excavator, we operate the hydraulic pressure experiment of electric motor project, which imitates the operating characters of classic machinery with the dynamometer of Eddy Current to measure the function.
Key Words: New-type driving force, energy conservation and environment
