Analyzing of influencing factors of stability of cutting unit of horizontal-axial-roadheader

On the basis of dynamic model of horizontal-axial-roadheader as transverse cutting,and the curve of vibration characteristics under different parameter was educed by using computer simulation,and analyse the connection between vibration characteristics and quality of cutting head and rocker, rigidity and damp of hydraulic system, which creat condition for studying vibration identity of horizontal-axial-roadheader and improving design.
