摘要
针对大功率采煤机牵引机构的动力学行为解析与结构参数优化问题,采用多维度交叉研究的方法,基于数值建模与机械架构设计,提出复合优化方法,并依托多体动力学-有限元联合建模体系,系统分析关键设计参数对牵引系统动态响应的影响机制。实证结果表明,优化后的牵引机构在复杂赋存地质环境中仍可维持良好的动态稳定性与高效作业性能;有效应对了高倾角作业面与非均质地质构造带来的技术挑战,有效延长了设备连续作业时间并降低了故障率;系统环境感知能力与生产效能同步增强,为智能化开采装备的性能优化提供了可参考的技术路径。
In view of the problems of dynamic behavior analysis and structural parameter optimization of high-power shearer traction mechanism,this paper uses a multidimensional interdisciplinary research method,propose a composite optimization method based on numerical modeling and mechanical architecture design,and systematically analyze the influence mechanism of key design parameters on the dynamic response of traction system based on the multibody dynamics-finite element joint modeling system.The empirical results show that the optimized traction mechanism can still maintain good dynamic stability and efficient operation performance in complex geological environment;effectively copes with technical challenges brought by high dip working surface and heterogeneous geological structure,and effectively extends the continuous operation time of equipment and reduces the failure rate;the system's environment perception capabil ity and production efficiency are enhanced synchronously,providing a reference technical path for the performance optimization of intelligent mining equipment.
