【摘要】 扫路车是重要的环卫设备之一，主要用于地面清扫、马路道牙边清扫、马路道牙清洗等工作，适用于各种气候和不同路面的清扫作业，更适合于广场、公路、住宅小区、停车场、码头、机场、车站、水泥厂、电厂等场所的清洁除尘。清扫车的工作装置多为由液压缸或者液压马达来驱动的。多功能、环保、经济等方面更加优化的扫路车应该是我国扫路车目前发展的主要方向。本文以通用底盘扫路车液压系统为研究对象，介绍了扫路车液压系统研究课题的来源与背景，并对扫路车液压系统国内外发展状况进行了总结与介绍。阐明了扫路车液压系统研究的理论意义与现实意义。通过对国内外扫路车液压系统应用和研究现状以及影响扫路车液压系统性能因素的分析，确定了影响扫路车液压系统性能的两个性能指标因素：液压缸及盘扫马达工作过程中其内部压力和流量变化情况。本文介绍了三种典型扫路车液压系统的原理，并总结了各液压系统的特点；对本文所研究的扫路车液压系统结构及原理进行介绍，提出该液压系统的性能要求，并对该液压系统的主要元件进行理论计算和分析，为液压系统的仿真分析奠定基础；使用工程系统仿真软件AMESim建立该扫路车液压系统模型，对其中各液压缸及马达工作过程中的油压和流量进行仿真分析，并对仿真结果进行分析。更多还原

【Abstract】 Road sweeper is one of the important cleaning equipment, mainly used forcleaning the ground, the road teeth edge dissection, the road teeth cleaning andwatering of the ground work, applicable to all kinds of climate and different roadsurface cleaning operation, and more suitable for the square, road, residential area,parking, dock, airport, railway station, cement factory, power plant and other places ofcleaning dust. Sweeper working device is composed of a hydraulic cylinder or ahydraulic motor to drive. Multifunction, environmental protection, economic andother aspects of a more optimized road sweeping vehicles in China should be maindirection of the road sweeper’s development in currently.Based on the special road sweeper hydraulic system as the research object, thefollowing introduces the source and background of the research subjects of roadsweeper hydraulic system,and the development situation of the road sweeping vehiclehydraulic system at home and abroad were summarized and introduced.Thetheoretical and practical significance of the road sweeper hydraulic system waselucidated.Through to the analysis of the domestic and foreign road sweeper hydraulicsystem application and research status and the influence of road sweeping vehiclehydraulic system performance,two performance indicators factors of the effect ofcleaning vehicle hydraulic system performance were determined: internal pressureand flow variations in working process of hydraulic cylinder and disc cleaner motor.This paper introduced three forms of road sweeping vehicles hydraulic systemprinciple that using more of the current domestic, and summarizes the characteristicsof hydraulic system; the road sweeper hydraulic system structure and principle areintroduced,put forward the performance of the hydraulic system,and analysis the main components of the hydraulic system as well as the theoretical calculation for thehydraulic system, and that have lay the foundation engineering for the hydraulicsystem simulation analysis.Use the engineering system simulation software AMESimto build the road sweeper hydraulic system model, and the oil pressure and flow in theworking process of each hydraulic cylinder and the motor are simulated, and thesimulation results are analyzed.更多还原
