GRAFEM/IFAD是机械CAD软件系统的应用软件之一,是机械设计的有力工具。本文首先介绍该系统的功能和特点,然后对装载机工作装置的铲斗和动臂结构进行了有限元分析,并用GRAFEM/IFAD的后处理功能给出了直观的应力与位移结果。最后将计算与实测结果做了对比分析,论证了这种分析方法的可信度。 GRAFEM/IFAD is one of the application software of mechanical CAD software system and it is a powerful tool for mechanical design. This paper first introduces the function and characteristics of the system. Then the finite element analysis is performed on the bucket and boom structure of the loader working device, and the direct stress and displacement results are given using the post-processing function of GRAFEM/IFAD. Finally, a comparative analysis of the results of the calculation and the measured results demonstrates the credibility of this method of analysis.
