【摘要】 基于有限元分析软件ANSYS和大型数学计算软件MATLAB对某煤机公司设计的薄煤层采煤机扭矩轴进行可靠性分析,获取不同深度的U型卸荷槽、不同开口角度的V型卸荷槽扭矩轴的应力变化规律;拟合出扭矩轴最大应力-时间变化曲线,并优化出扭矩轴卸荷槽的结构尺寸,同时结合由机械系统运动学和动力学自动分析软件ADAMS,仿真生成的扭矩轴所受峰值时刻的动载荷,验证改进后扭矩轴的可靠性和合理性。更多还原

【Abstract】 Analyse the dependability of the wrench moment axis of the thin coal seam shearer which designed by a coal machine company based on the finite element analysis software ansys.Get the stress-change rule of different U-groove wrench moment axis and V-groove wrench moment axis.Draw up the stress-time curve,and optimize the configuration of the wrench moment axis wrench moment axis.And examine the dependability and rationality of the improved wrench moment axis with the active peak-value load,which got from the automatic dynamic analysis of mechanical systems software adams.更多还原
