摘要
在考虑了摇臂的刚度、阻尼以及采煤机与运输机的接触刚度的基础上 ,建立了采煤机工作时的刚体动力学模型和数学模型 ,为利用计算机模拟滚筒、机身的振动和特征参数及分析奠定了基础。
On the basis of considering rigidity,damping of ranging booms and contact rigidity between shearers and conveyors,rigid body models and mathematical models under the operation of shearers are set up in the paper,which lays the foundation of simulating the vibration of drums and fuselages and analyzing the characteristic parameters by means of computer programs.
