【摘要】：全液压凿岩台车凭借其能耗低、污染少、可靠性高、经济效益好等优点,在能源开发、交通运输、水电工程以及国防建设等重大工程建设中得到了广泛的应用,它将施工人员从繁重、艰苦的凿岩作业中解放出来,同时也有效地提高了资源利用率。凿岩台车给进支撑系统是液压凿岩台车的关键部分,其性能的优劣直接影响凿岩台车的整体性能。本课题来源于鞍山钢铁集团矿业公司眼前山铁矿全液压凿岩台车研制项目,该项目以阿特拉斯·科普柯某型凿岩台车为例进行相关凿岩台车研制。本文重点以液压凿岩台车给进支撑系统为研究对象,通过现场实地测量,建立给进支撑系统三维模型,并对其进行了动力学特性以及有限元分析,得到各关键部件的力学特性数据,为凿岩台车的研制工作提供了指导。本文首先以瑞典阿特拉斯·科普柯公司某掘进凿岩台车为实例,通过现场实地测量,得到台车的三维数据信息并参考相关资料,绘制出凿岩台车给进支撑系统三维模型,将各部件进行装配并进行相关干涉检查后,得到凿岩台车给进支撑系统的三维装配体模型。其次,在装配体模型的基础上,将其导入ADAMS中,得到台车给进支撑系统虚拟样机模型。结合凿岩台车实际工作状况,对凿岩台车给进支撑系统的六个主要危险工况进行动力学仿真分析,得到给进支撑系统各关键部件的动力学相关曲线,为驱动油缸的选取及优化提供了必要参考,同时也为给进支撑系统零部件的有限元分析提供了数据支持。最后利用ANSYS Workbench对不同工况下的凿岩台车给进支撑系统进行了静力学及模态分析,得到整个系统及各部件的应力及变形情况,以及系统容易发生共振的频率、振型及其相应变化趋势,为以后凿岩台车给进支撑系统避开共振区域频率提供了依据。
[Abstract]:Full hydraulic rock drilling trolley has been widely used in energy development, transportation, hydropower engineering and national defense construction because of its advantages of low energy consumption, less pollution, high reliability and good economic benefits. It liberates the construction personnel from heavy and arduous rock drilling operations, and also effectively improves the utilization rate of resources. The feed support system of rock drilling trolley is the key part of hydraulic drilling trolley, and its performance directly affects the overall performance of rock drilling trolley. This subject comes from the development project of full hydraulic drilling trolley in Qianshan Iron Mine of Anshan Iron and Steel Group Mining Company, which takes Atlas Copco as an example to develop the related drilling trolley. In this paper, the feed support system of hydraulic drilling trolley is taken as the research object, through field measurement, the three-dimensional model of feed support system is established, and its dynamic characteristics and finite element analysis are carried out, and the mechanical characteristic data of each key component are obtained, which provides guidance for the development of rock drilling trolley. In this paper, taking a drilling trolley of Atlas Copco Company of Sweden as an example, through field measurement, the three-dimensional data information of the trolley is obtained and the three-dimensional model of the feed support system of the drilling trolley is drawn. After assembling each component and checking the relevant interference, the three-dimensional assembly model of the feed support system of the drilling trolley is obtained. Secondly, on the basis of the assembly model, the virtual prototype model of the trolley feed support system is obtained by importing it into ADAMS. Combined with the actual working condition of the drilling trolley, the dynamic simulation analysis of the six main dangerous working conditions of the feed support system of the drilling trolley is carried out, and the dynamic correlation curves of the key components of the feed support system are obtained, which provides the necessary reference for the selection and optimization of the driving cylinder, and also provides data support for the finite element analysis of the parts and components of the feed support system. Finally, the statics and modal analysis of the feed support system of rock drilling trolley under different working conditions are carried out by using ANSYS Workbench, and the stress and deformation of the whole system and its components, as well as the resonance frequency, vibration mode and its corresponding changing trend of the system are obtained, which provides the basis for the future feed support system to avoid the frequency of resonance area.
