摘　　要：有限元分析理论的提出为复杂机械性能问题的研究提供了有效方法。文章以井下刮板输送机链轮为研究对象,利用有限元分析方法对机械模态进行研究。通过对前10阶模态的计算,得出了固有频率的影响值范围,并以链轮轮齿厚度和宽度为例分析了机械设计中要回避的制造参数。此研究为煤矿机械设备的优化和改进提供了有效途径。I this paper, the finite element analysis theory provides an effective method for the study of complex mechanical performance problems. Taking the underground scraper conveyor sprocket asked the research object, research on the machine model using finite element analysis method. Through calculation of the first 10 order modes, the effect of frequency range, and the sprocket tooth thickness and width as an example to analyze the manufacturing parameters in the mechanical design to avoid. This study provides an effective approach for the optimization and improvement of coal mine machinery equipment.
