【摘要】：装载机是用来实现松散物料的装卸、铲掘等任务的,其中工作装置是作业的执行部件,其机构及结构的特性直接影响整机性能和作业生产率。随着CAD技术的成熟和各种现代设计方法的完善,对产品的设计提出了自动化、智能化的要求,而传统的设计方法已不能满足产品开发周期短、生产成本低的要求。综合应用各种理论和成熟软件开发一套方便快捷且可靠性高的设计系统具有重要的应用价值,同时也是现代设计理论的发展趋势。本文主要是以装载机工作装置为例,研究开发包含参数化设计、三维建模和有限元分析的集成系统。以VC++6.0为软件开发平台,首先利用复杂连杆机构的型转化理论,对装载机工作装置进行理论分析,建立力学模型和数学模型,并编程实现装载机新型八连杆工作装置的运动分析和受力分析,实现了计算数据的数据库读写功能,利用VC++6.0的绘图功能对机构进行运动仿真,可快速、真实再现机构的各种性能并作出评价;然后结合参数化三维建模理论对SolidWorks进行二次开发,实现装载机工作装置的三维实体建模;最后借助于APDL语言对有限元分析软件ANSYS进行二次开发,通过分析对设计结果的合理性做出判断,确定设计方案。
[Abstract]:The loader is used to carry out the tasks of loading and unloading loose materials, shovel, and so on, in which the working device is the executive part of the operation. With the maturity of CAD technology and the improvement of modern design methods, the requirement of automation and intelligence for product design is put forward. However, the traditional design method can not meet the requirements of short product development cycle and low production cost. It has important application value to develop a set of convenient, fast and reliable design system by comprehensive application of various theories and mature software. At the same time, it is the development trend of modern design theory. In this paper, an integrated system including parameterized design, 3D modeling and finite element analysis is developed by taking the working device of loader as an example. With VC 6.0 as the software development platform, the model transformation theory of complex linkage mechanism is first used. In this paper, the working device of loader is analyzed theoretically, the mechanical model and mathematical model are established, and the motion analysis and force analysis of the new eight-bar working device of loader are realized by programming, and the database reading and writing function of calculating data is realized. Using the drawing function of VC 6.0 to simulate the motion of the mechanism, it can quickly, truly reproduce and evaluate the various performances of the mechanism, and then combine with the theory of parametric 3D modeling to carry out the secondary development of SolidWorks. Finally, the finite element analysis software ANSYS is redeveloped with the help of APDL language, and the design scheme is determined by analyzing the rationality of the design results.
