摘　　要：液压绞车是一种用途广泛的起重设备,其中卷筒是关键的承力部件。为了清楚把握卷筒的力学特性,建立了卷筒的三维模型,研究了卷筒的应力和变形情况。研究结果表明,卷筒承受的应力从中部往两边逐渐减小,且内表面的应力大于外表面;由于在筒壁与侧板连接处做了圆角处理,避免了应力集中;卷筒整体变形不大,变形量从中部往两边变形逐渐减小,最大变形出现在内表面处。研究结果可以为卷筒的设计提供一种参考方法,同时为下一步的优化设计提供理论基础。Hydraulic winch is widely used hoisting equipment,and roller is one of the main force-supporting parts.To grasp the mechanical properties of the roller,its 3D model was built to study its stress and deformation.The results showed that the stress of the roller decreases from the center to the both sides,and the value on the inner surface is bigger than that on the outer surface.Because of the round corner is made between the roller wall and the side plate,the stress concentration is avoided.The whole deformation of the roller is small,and the deformation decreases from the center to the both sides,and the max deformation appears on the inner surface.The research results provide certain theoretical reference for the optimization design of the disc brake.
