【摘要】：智能型步履式挖掘机是新兴的特种机械，可广泛用于各种施工现场，如抢险救灾、空间狭小、山地等普通施工机械无法到达的地点，所以智能型步履式挖掘机的安全性能和施工效率等受到极大的关注。使用传统方法已经不能满足设计的要求。本文使用三维工程软件研发设计智能型步履式挖掘机并进行动态仿真分析。本文在综合调查和分析了智能型步履式挖掘机在国内外的发展现状的基础上，基于智能型步履式挖掘机结构和行走控制方式，利用三维仿真软件模拟技术，分析其运动学和动力学仿真状态，确定了底盘的危险的工作状态，并据此进行了底盘主体的强度分析、稳定性分析等。全文主要从以下方面进行了阐述：首先，分析了智能型步履式挖掘机的国内外发展形势和结构特点，并对其操作方法进行了总结介绍。其次，进行了智能型步履式挖掘机数学模型的建立和整体稳定性问题的研究。再次，使用SolidWorks三维软件绘制了整机的三维模型。使用多体动力学仿真软件Simulation/Motin对底盘进行了动态分析。在仿真结果的基础上确定了底盘的最危险工况。根据载荷的边界条件还进行了结构疲劳分析。
[Abstract]:Intelligent walking excavator is a new type of special machinery, which can be widely used in various construction sites, such as rescue and disaster relief, narrow space, mountainous areas and other common construction machinery can not reach the location, Therefore, the safety performance and construction efficiency of intelligent walking excavator have received great attention. The use of traditional methods can no longer meet the requirements of the design. In this paper, the intelligent walking excavator is developed by using three-dimensional engineering software and dynamic simulation analysis is carried out. Based on the comprehensive investigation and analysis of the present situation of intelligent walking excavator at home and abroad, this paper makes use of 3D simulation software simulation technology based on the structure and control mode of intelligent walking excavator. The kinematics and dynamics simulation state of the chassis is analyzed, and the dangerous working state of the chassis is determined. Based on this, the strength analysis and stability analysis of the chassis body are carried out. Firstly, the development situation and structure characteristics of intelligent walking excavator at home and abroad are analyzed, and its operation methods are summarized and introduced. Secondly, the mathematical model of intelligent walking excavator and the whole stability are studied. Thirdly, the 3D model of the whole machine is drawn with SolidWorks software. The dynamic analysis of the chassis is carried out by using simulation / motin, a multi-body dynamics simulation software. On the basis of the simulation results, the most dangerous working conditions of the chassis are determined. Structural fatigue analysis is also carried out according to the boundary condition of the load.
