无绷绳修井机稳定性仿真分析

摘要

对无绷绳修井机井架进行了特征值屈曲分析,得出了频率和载荷之间的关系,并确定了井架结构形式.根据整机稳定性要求,分析了工作状态时的整车稳定性,通过改进支撑方案,使整车稳定系数达到了设计要求.%The analysis of flexuosity for the workover rig with out guy line was made and the relation between frequency and load was obtained to determine the mast configuration of the rig. To meet the stability requirement of whole rig,the analysis of working stability was made through improvement thus the design requirement was achieved.
