摘要
为了提高牵引器的牵引能力和井下适应性，建立牵引器驱动装置的参数优化计算模型，对驱动装置的接触力系数以及驱动臂与支撑臂的长度、张开角等相关参数进行分析和优化计算，分析牵引器的越障能力。分析结果表明：接触力系数越低，则牵引力越大，且随驱动臂和支撑臂的张开角的增大而减小，随该角度的增大而变化趋势减缓。基于177．8 mm（7英寸）套管的实例，验证和计算了牵引器驱动装置各参数之间的变化关系和优选范围值。
Abstract
In order to improve the traction ability,down-hole adaptability of tractor,a parameters optimization calculation model for the drive device of tractor was established.Relevant parameters of drive device including contact force coefficient,open-angle and length of drive arm,open-angle and length of support arm and obstacle-surmounting ability of tractor were analyzed and optimal calculated in this paper.The analysis result indicates the contact force coefficient smaller the grea-ter traction is.Noreover,the contact force coefficient decreases with the increase of open-angle of drive arm and support arm,changes smaller along with the increase of angle.In addition,the pa-rameters’changing relationship of drive device and the optimal range of values were verified and calculated.
