| 摘 要： | 以结构有限元分析为基础 ,利用优化技术 ,以耗用结构型钢最少为目标 ,探讨车装钻机井架的合理结构形式。用ZJ2 0钻机井架为例进行计算 ,结果表明 :井架结构布置方式对型钢耗用有较大的影响 ,采用合理的结构形式 ,可比现有井架节约型钢 4 0 %左右 ;井架前倾角的大小影响到井架的承载能力 ,为满足承载要求 ,前倾角小于6°为宜 ;井架所用型钢较合理的选择是 :腿杆是冷弯矩形空心型钢 ,横斜杆用热轧等边角钢。

| Abstract: | On the basis of FEM,using optimization technology,reasonable structure of the derrick in mobile drilling rig is studied with aim at the minimum consumption of shaped steel.Taking the derrick of ZJ20 drilling rig for example,calculations have been done with computer.The results show that 50% consumption of shaped steel can be cut down on reasonable structure of the derrick,and the inclination of the derrick should not be more than 6 degrees,and it is advisable to use rectangle steel pipes as derrick legs and angle steel as girders and braces of derrick. |
