摘　　要：本文以J71A型薄煤层大功率采煤机摇臂为例,首先,基于ADAMS程序构建刚-柔混合模型,开展采煤机摇臂模态分析,确认采煤机摇臂在不同阶数下的固有频率,其次,基于模态分析结果提出优化方案,开展优化前后静力对比分析,初步检验优化方案的有效性,最后将优化方案应用于工程实践,进一步检验优化方案的实施。This paper takes J71A high power shearer rocker in thin seam as an example.Firstly,a rigid flexible Mixture model is built based on ADAMS program,modal analysis of shearer rocker is carried out to confirm the natural frequencies of shearer rocker in different orders.Secondly,based on the results of modal analysis,an optimization plan is proposed,static comparative analysis before and after optimization is carried out to preliminarily verify the effectiveness of the optimization plan.Finally,the optimization plan will be applied to engineering practice to further verify the implementation of the optimization plan.
