摘　　要：针对9QY55圆捆压捆机底盘机架在使用过程中出现的异常变形问题,进行了机架在弯曲和扭转工况下的应力及变形分布情况的有限元分析,得出的导致变形的危险区域与机架异常变形情况相吻合。根据分析结果对机架结构进行了改进和比较分析,确定了减小最大应力及最大变形的合理化设计方案。based on abnormal deformations with the chassis of 9QY55 round balar during its operation, the finite element analysis of the stress and deformation distribution condition under bending and torsion condition is carried out. The dangerous areas that cause the deformations are found, which matches the abnormal deformation conditions of the frame. The improvement and comparison analysis on the frame structure is carried out based on the analysis result, the reasonable design scheme to reduce the maximum stress and maximum deformation was determined.
