【摘要】 建立液压支架平衡千斤顶力学模型,以立柱柱窝到顶梁铰接点的距离为变量来研究平衡千斤顶受力,利用VB对其进行编程,实现平衡千斤顶受力曲线的自动绘制。所设计的系统界面友好,便于液压支架设计中使用。更多还原

【Abstract】 Mechanics model of the balance ram is set up in the shield hydraulic support,and takes the distance between intersection of the column and the link joint of the top beam as variables to analyse stress in the balance ram.Then program with VB to automatically get the curves of stress of the balance ram.And the designed system interface is friendly,and convenient used in the process of the design of the balance ram.更多还原
