摘　　要：基于接触动力学有限元理论,运用LS-DYNA模块参数化方法,对采煤机行走轮与销排啮合进行非线性动态接触分析,并进行模拟分析对比,得出整个啮合过程应力、应变及由啮合冲击引起的相关动态特性。模拟结果与实际情况相吻合,此方法可用以指导产品实际设计。Based on contact kinetics finite element theory,the development of road wheel and pin mesh＇s nonlinear dynamic contact was analyzed in parametric method of LS-DYNA module,and can carry out contrast of simulation analysis,achieve stress,strain and dynamic identities that caused by meshing impact in the whole meshing process.The results of simulation are accord with the practice.The method of analysis can be used to instruct the design of product practice.
