刨煤机平面振动的数学建模与仿真

Modeling and Simulation of Planar Vibration of Plough

为了降低刨头的振动,提高刨煤机的工作性能,通过简化和假设,应用牛顿定律建立了刨煤机在垂直煤壁方向振动和在水平面扭转振动的数学模型,通过对刨煤机的实体模型进行简化并导入Adams软件,得到了刨头沿垂直煤壁方向和平面扭转振动的仿真曲线,为研究刨煤机的振动、改进设计、合理确定刨煤机的参数提供了理论依据。

In order to decrease the vibration of a plow head and improve the working performance of a plough, Newton law is used to establish the mathematical model of vibration for a plough in a perpendicular to the coal wall and torsional vibration in horizontal plane in the paper. The entity of plough is simplified and assumed and exported to Adams software, then simulation curves of two these conditions are obtained, which lays a theory foundation for researching the vibration of plough,improving the design quality and choosing reasonably parameters of a plough.
