摘　　要：在有限元理论的基础上,建立了三维颚式破碎机动颚齿板齿形的有限元分析模型,研究了三角形、圆弧形、梯形齿在破碎过程中的等效应力分布规律。通过对有限元分析数据与实验数据比较分析,认为三角形齿破碎效果好,但是应力分布较大,易损坏;圆弧形齿面强度高,应力分布较小,使用寿命长。在综合三角形和圆弧形齿优点的基础上优化了梯形齿形,提高了齿面强度,减小了应力集中,延长了齿板的使用寿命,提高了破碎效率。Based on finite element theory, a finite element analysis model is built for tooth profile of moving jaw plate of three- dimension jaw crusher, studied the equivalent stress distribution law in triangle, circular arc and trapezium tooth in crush. Based on the comparison and analysis between finite element analysis data and experiment data, it is considered that the crushing effect is better with triangle tooth but accompanied by large stress distribution and the tooth easy damaged; the circular arc tooth is of high strength, small stress distribution and long work life. The trapezium tooth is optimized on the base of comprehensive superiorities of triangle and circular arc, has higher tooth surface strength, small stress concentration, longer work life and so crushing efficiency got raised.
