摘　　要：前机架是矿用地下装载机的主要结构件之一,前机架在需要符合强度等力学条件之外,还需要满足一定的动态特性要求。文中在Solid Works中建立了前机架的三维实体模型,导入到ANSYS中进行有限元设定和分析,得到前机架前8阶固有频率及振型,结合柴油机与路面激励进行分析,为前机架的进一步改进设计提供了依据。The front frame is one of the main structural parts of the underground loader, which needs to meet the strength and other mechanical requirements, but also needs to meet the requirements of dynamic characteristics. Three-dimensional solid model of the front frame was built in Solid Works, and then front frame 8 natural frequencies and mode shapes are obtained by importing the model to ANSYS finite element setting and analysis. Comparative analysis of the results with engine and road excitation, which provides references for further improve the design of the front frame.
