摘要
为了解决纵轴式部分断面掘进机在钻进过程中,截割头几何参数、运动参数对截齿的速度、加速度影响问题。通过分析,给出掘进机钻进时截齿的运动轨迹,建立了掘进机在钻进工况下单个截齿的螺旋线方程,并导出其运动速度和加速度的方程,所建立的运动学模型为研究掘进机钻进工况的运动学、动力学特征,改善机器工作性能奠定基础。
To solve the effects of cutting geometry parameter and kinematics parameters on truncation tooth speed and acceleration in the drilling progress of part-face longitudinal-axial-roadheader. Through analysis the moving path of the truncation tooth is given when the roadheader is drilling. The single truncation tooth spiral line equation of the roadheader in drilling condition is established. The equation of the movement velocity and acceleration is derived. The moving model established will lay the foundations for the kinematics and dynamics characteristics research of roadheader cutting patterns and the improvement of machine operating perfomences.
