连续采煤机转向的动力学仿真模型

Dynamic simulation model of steering of a continuous miner

在对连续采煤机的假设条件的基础上采用机械系统动力学分析与建模通用方法,通过总体参考系、动参考系、连体参考系来描述连续采煤机与地面运动和相互作用关系,对其在水平硬地面转向过程进行了动力学分析和建模。这个模型对于连续采煤机的整机动力学建模、动力学性能的研究有着积极的作用。

On the basis of the assumed conditions for the continuous miner, with the methods dynamics analysis of mechanical system and model building, continuous miner's movement and interaction with the ground are described through the global coordinates, the relative coordinates and fixed-body coordinates. The dynamic analysis and model building are carried out of the steering procession on the hard level ground. This model has positive role in the building of the whole machine's dynamics model and the research on dynamics performance on the continuous miner.
