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 protection, Construction machinery of electric motor, power source, hydraulic 目 录 1 绪论 ………………………………………………………………………… 6 1.1电驱工程机械试验平台简介……………………………………………… 6 1.2 概述 ……………………………………………………………………… 6 1.3目前工程机械动力源…………………………………………………… 6 1.4采用液压系统的优缺点…………………………………………………… 6 2 液压系统的原理……………………………………………………………… 9 2.1电驱工程机械试验平台液压系统原理图………………………………… 9 2.2电驱工程机械试验平台液压系统原理分析…………………………… 9 3 计算………………………………………………………………………… 10 3.1主要技术性能参数……………………………………………………… 10 3.2泵的相关计算……………………………………………………………… 10 3.3马达的相关计算…………………………………………………………… 11 3.4油管的相关计算……………………………………………………………11 3.5油箱的容量计算…………………………………………………………… 11 4 电动机和测功仪的选择…………………………………………………… 12 4.1电动机的选择……………………………………………………………… 12
