纵横轴式掘进机工作稳定性的模拟分析

In order to understand deeply cutting particularity of roadheader, stability of cutting was researched. By using the method of simulation analysis, through force analysis of cutting of longitudinal-axis and horizontal-axial roadheaders, mathematical models for these two kinds of cutting stability were established in the paper. Stability ratio of simulation curve were obtained by means of Matlab simulation software. Variation characteristics of stability were also obtained by comparative analysis of load spectrums, which provides theoretical basis for performance comparison of and reasonable selection of longitudinal-axis and horizontal-axial roadheaders. The results show that the stability of two kinds of roadheader is better, besides the stability of horizontal-axis is higher than longitudinal-axis roadheader in longitudinal and horizontal cutting.
