摘要
根据计算机模拟的载荷谱,提出采煤机螺旋滚筒外载荷的变化可用简谐振动的规律来模拟.据此,建立了采煤机振动的简化力学模型,并对其中的基本参数进行了分析.
According to computer simulation load chart of drum (shearer, the authors approached the vibration rule of drum load by simple harmonic motion, derived the mechanical models and differentiation equation of shearer and drum vibration, analysed its parameters and some conclusions were obtained.
