【摘要】：随着经济的发展和工业化进程的加快,能源消耗和环境问题之间的矛盾越来越突出,已成为制约经济发展的首要问题。世界各国针对此问题都采取了不同的措施,但主要还是从节能方面进行控制,针对环保要求越来越高的大环境下,各式各样的节能汽车如雨后春笋般的被投向市场。因此,世界一些大的工程公司看到了这一商机,都纷纷把混合动力工程机械作为一个新的研发方向。本文以YHC-6型地下铲运机为目标,研究在正常工况下的动力特性,铲运机在各工况下的能量传动,功率分配,分析获得一个工作循环下铲运机功率和载荷随时间变化的关系。根据铲运机动力系统的组成,提出了适用于铲运机工作循环的作业方式,对铲运机零部件和整体受力进行了分析,用Solidworks三维绘图软件绘制了YHC-6型地下铲运机的实体模型,用ADAMS分析软件建立了样机的模型并进行了分析,通过对地下铲运机工作机构进行动力学仿真,得出了铲运机在各种载荷作业条件下载荷变化相互之间的关系。本文所提出的工作模式、载荷特征、地下铲运机工作循环下工程特性和混合动力系统结构方案进行分析的方法,为下一步混合动力铲运机在能量流动和分配方面提供了基础数据和新方向。
[Abstract]:With the development of economy and the acceleration of industrialization, the contradiction between energy consumption and environmental problems is becoming more and more prominent, which has become the most important problem restricting economic development. Countries all over the world have taken different measures to solve this problem, but mainly from the aspect of energy saving control. Under the environment with more and more high environmental protection requirements, all kinds of energy-saving vehicles have been put into the market like bamboo shoots after a spring rain. Therefore, some of the world's largest engineering companies have seen this business opportunity, have taken hybrid engineering machinery as a new research and development direction. In this paper, the dynamic characteristics of YHC-6 type underground scraper under normal working conditions are studied, the energy transmission and power distribution of the scraper under each working condition are studied, and the relationship between power and load changes with time under a working cycle is analyzed. According to the composition of the power system of the scraper, the operation mode suitable for the working cycle of the scraper is put forward, the parts and components of the scraper and the whole force are analyzed, and the solid model of the YHC-6 type underground scraper is plotted with Solidworks 3D drawing software. The model of the prototype is established by using ADAMS analysis software, and the dynamic simulation of the working mechanism of the underground scraper is carried out. The relationship between the load changes of the scraper under various load working conditions is obtained. In this paper, the working mode, load characteristics, engineering characteristics under the working cycle of underground scraper and the structural scheme of hybrid power system are analyzed. It provides basic data and new direction for energy flow and distribution of hybrid LHD in the next step.
