【摘要】：世界范围内城市化进程的加快与道路建设的迅猛发展产生了大量的废弃路面混凝土，将混凝土路面切割后加工成可利用产品是废弃路面混凝土回收利用的一条有效途径，而切割设备的性能对废弃路面混凝土的回收利用有重要影响。目前，大多数路面切割机存在着功率较低、切割深度小以及作业直线性不能保证等问题。因此，研发一款大切深、有轨道的直线型作业以及采用全液压传动方式驱动的路面切割机，具有重要的现实意义。本文在对YFSJ2000型混凝土切割机工作原理和作业工况分析的基础上，设计了能满足作业需求的整机液压系统包括切割系统、行驶系统和整机侧移系统；提出了行驶液压系统的合流方案，提高了系统的工作效率；根据实际作业工况，，对YFSJ2000型切割机的液压系统进行了参数匹配，对行驶系统和切割系统的泵和马达及各液压缸等主要工作元件进行了参数计算、校核和选型；在AMESim环境下分别建立了切割液压系统及行驶液压系统的仿真模型，通过仿真试验，验证了所设计的液压系统及参数匹配的合理性。
[Abstract]:The acceleration of urbanization and the rapid development of road construction in the world have produced a large number of abandoned pavement concrete. It is an effective way to recycle the waste pavement concrete by cutting the concrete pavement into a usable product. At present, most pavement cutting machines have some problems such as low power, low cutting depth and unguaranteed straightness. Linear operation with track and road cutting machine driven by hydraulic drive have important practical significance. Based on the analysis of the working principle and working conditions of YFSJ2000 type concrete cutting machine, the hydraulic system of the whole machine, which can meet the requirement of operation, is designed, which includes cutting system, driving system and whole machine lateral shift system. The combined flow scheme of driving hydraulic system is put forward, and the working efficiency of the system is improved. According to the actual working conditions, the parameters of hydraulic system of YFSJ2000 cutting machine are matched. The parameters of pump, motor and hydraulic cylinder of driving system and cutting system are calculated, checked and selected, the simulation models of cutting hydraulic system and driving hydraulic system are established under AMESim environment, and the simulation tests are carried out. The rationality of the hydraulic system and parameter matching is verified.
