摘　　要：根据充填采煤液压支架结构原理及控顶作用,建立了支架顶梁的力学模型,分析得出了顶梁受力情况及3排立柱受力之间的关系;运用Pro/E软件对支架进行三维建模和运动学仿真分析,模拟出主要部件的运动过程,得出各主要部件在工作过程中的运动特征曲线,并对支架参数进行了校核.基于以上分析结果设计制造了ZZC8800/20/38型充填采煤液压支架,支架前、后排立柱受力分别是中立柱支架受力的4.1倍、4.6倍.该支架在平煤十二矿成功应用表明受力分析及设计是科学合理的.A mechanical model was constructed to analyze the mechanics of the top beam and three rows of columns of a new type hydraulic support. Pro/E software code was then used to simulate the three dimensional model and estimate its kinematic properties. Movement in the main components of the support was simulated and curves relating movement to stress were ob- tained. These analyses were used to design the ZZC8800/20/38 hydraulic support with front legs or tail legs, having respectively 4.1 or 4.6 times the power of the middle legs. This design has safely been applied to one coal face in the Pingdingshan XII mine. The application verified the practicality of this particular design.
