工程机械多功能试验台用于工程机械的牵引及加载试验。该试验台可悬挂工程机械多种工作装置,以研究工程机械工作装置的作业机理和性能参数的选择。试验台主要由机械结构系统、液压系统、控制系统、测试系统和电力系统等组成。根据试验台的机械结构设计、性能参数以及用途与功能,详细分析了液压驱动系统(牵引或加载液压驱动系统、工作装置液压驱动系统和辅助液压驱动系统)的组成、工作原理和技术特点。
Construction machinery multi-purpose test bench for construction machinery traction and loading test. The test stand can be hung a variety of construction machinery working equipment to study the operating mechanism of construction machinery and equipment performance parameters of the choice. The test bench is mainly composed of mechanical structure system, hydraulic system, control system, test system and power system. According to the mechanical structure design, performance parameters, use and function of the test rig, the composition, working principle and technical characteristics of the hydraulic drive system (traction or loading hydraulic drive system, working device hydraulic drive system and auxiliary hydraulic drive system) are analyzed in detail.
