一、概述牙轮钻机高钻架是由250多根等直秆、10多根非等直杆和几处薄板件焊接而成的空间工程结构。对于这种大型并且比较复杂的空间结构来说,用手算很难实现强度分析,为了检验钻架的工作可靠性与经济合理性,并企图为今后的钻架设计及改进提供一点参考资料,有必 I. Overview Rotary drilling rig The high drilling rig is a space engineering structure that is welded by more than 250 straight stalks, more than 10 non-straight bars and several thin plate parts. For this large-scale and more complex space structure, it is difficult to achieve strength analysis by manual calculation, in order to verify the reliability and economic rationality of the drilling rig, and to provide a reference for the future design and improvement of drilling rigs.
