摘要

采煤机在工程过程中承受着复杂的载荷冲击,这会使得采煤机截割部出现复杂的振动现象,这种复杂的振动现象一方面会增加螺旋滚筒、摇臂壳体和齿轮传动机构等部件的工作负担,另一方面也会对采煤机的截割性能造成影响。为研究采煤机截割部的工作稳定性,采用集中参数建模法建立采煤机的竖直方向和水平方向振动数学方程,并利用Matlab对其进行求解,得到截割部外载荷作用下,处在不同工作角度时的时域和频域振动特性规律,然后利用刚柔耦合混合建模的方法,建立截割部的三维模型,利用Adams和Ansys联合对截割部的负载进行了动力学仿真分析,得到采煤机截割部动态响应。为研究采煤机截割部的动力学特性提供了新的方法,分析结果为改进采煤机截割部设计、提高其工作稳定性提供了依据。

Abstract

The shearer is under complex impact when it works. and it makes the shearer cutting unit vibrate,which increase the burden of the spiral drum and rocker arm shell. Besides,it would bring bad effects to the shear performance of the shearer. In order to study its study the working stability,the vibration mathematical equations in vertical direction and horizontal direction was established by lumped parameter modeling method and solved by the software of MATLAB. And acquire the vibration characteristics when working in different angles of time and frequency domain. The 3D model of the shear cutting unit was established by rigid and flexible coupling method. By the dynamic simulation and analysis from the software of ANSYS and ADAMS,the dynamic response of the shear cutting unit was acquired. The study provide a new method for the analysis of the dynamic response and basis to improve the design and stability of the shear cutting unit.
