目前，我国煤矿井下装载主要靠人工和采煤机来实现，装载机的使用尚处于起步阶段，因此矿用防爆装载机的研制对提高井下装载效率及自动化程度具有重要的现实意义。防爆装载机工作装置作为实现铲料、运料和卸料的重要机构，其合理性将直接影响着整机性能。本文将虚拟样机技术引入到工作装置设计中，通过运动学、动力学仿真分析，为防爆装载机工作装置的设计提供了可靠依据。 本课题在分析矿用防爆装载机工作装置运动过程的基础上，建立了工作装置运动学数学模型，确定了其基本设计参数和总体参数。在Pro/E软件中建立了工作装置的三维实体模型，并进行了虚拟装配。通过对该工作装置的三维可视化干涉检查、运动轨迹、运动包络和运动学分析，验证了所建立的运动学数学模型的正确性，并对工作装置进行了有限元分析。 本文还在经典动力学分析软件ADAMS中建立了防爆装载机工作装置的多刚体虚拟样机，通过以多刚体动力学理论为基础的运动学、动力学分析，得到工作装置的运动学、动力学特性曲线。在此基础上，进一步建立了刚性体和柔性体耦合的工作装置虚拟样机，得到含有柔性体的工作装置运动学、动力学特性曲线，并对两种虚拟样机的仿真结果进行了比较，证明含有柔性体的虚拟样机更接近实际物理样机。 本文研究工作为新型防爆装载机工作装置的设计和研究提供一种有效的手段。所得结论不仅对工作装置物理样机的试制和性能评估具有重要的指导意义，而且对其它复杂机械设备的运动学、动力学分析及虚拟样机的建立具有一定参考价值。

In the coal mining industry of our country, so far, the mining loading is mainly conducted by the manual mean and shearer, the application of loader is still in the infancy stage. So it is very important to develop the mining anti-explosion loader for improving the efficiency and the level of automatization of mining loading. As the vital mechanism of spading, transporting and unloading minerals, the rationality of the work equipment of the mining anti-explosion loader will affect directly the performance of whole machine. In this present work, the technology of virtual prototype is introduced to instruct the work equipment design by the simulation of kinematics and dynamics. In terms of the kinematic scheme analysis of work equipment of the mining anti-explosion loader, its kinetic model is established, and its basic design parameters and whole ones are determined in this research work. Subsequently, the 3D modeling and virtual assembly of the work equipment are accomplished in the Pro/E software, and by the 3D visualization interferential checking and the kinetic locus and wrapping analysis, the validity of the established kinetic model is verified. At the same time, the finite element analysis is performed for the work equipment. In addition, by means of the classical dynamic simulation software ADAMS, the multi-rigid bodies virtual prototype machine is built for the work equipment of the mining anti-explosion loader. Via the kinematic and dynamic simulation based on the multi-rigid bodies dynamics theory, the kinetic and dynamic characteristic curves of the work equipment are obtained. Based on these investigations, the virtual prototype machine coupling rigid bodies with flexible ones is established eventually. By comparing the obtained the kinetic and dynamic characteristic curves and the corresponding simulation results from the latter with those of the former, it is shown that the virtual prototype machine with flexible bodies is more accordant with the physical prototype machine than the former. The research work provides with a valid designing and developing means for the work equipment of the new-style anti-explosion loader. The obtained conclusions not only are important to instruct the trial-produce and performance evaluation of the physical prototype of work equipment, but also are valuable for the kinetic and dynamic simulation and the establishment of the virtual prototype of other complicated mechanical devices.
