摘　　要：针对挖掘机斗杆液压油缸出现的"拉缸"问题,全面分析了导致"拉缸"的原因。利用力的分解模型,分析出了安装孔的平行度偏差对液压油缸承载的影响方式,利用ANSYS软件建立了斗杆液压油缸有限元计算模型,并计算出两种工况下液压油缸的应力分布云图,从而明确了平行度对液压油缸承载的影响程度。根据分析结果,对斗杆液压油缸的安装孔平行度进行了调整,改进后油缸"拉缸"反馈率明显下降。The reason of scuffing of cylinder from market feedback is fully analyzed to excavator bucket handle. The effect way of installation hole parallelism＇ deflection to load of hydraulic cylinder is gotten. The finite element model of bucket handle hydraulic cylinder is founded and the stress is calculated by ANSYS software. Parallelism＇ deflection to hydraulic cylinder＇ load is clear from the calculation. The improvement of bucket handle hydraulic cylinder parallelism is done according to the analysis result and the feedback of scuffing cylinder from market is reduced greatly.
