制动带机械应力场分析与试验研究

摘要

The 3D-model of brake band subassembly is established with Pro/E software for finite element method analysis.The Mechanical Stress Field of band brake is analyzed by using MSC.NASTRAN software.The stress field is revealed under the rated condition and the failure condition.The stress of brake band is obtained through experiments.The correction of the 3D-model of the brake band is verified.%采用三维CAD软件建立了制动带组件的三维实体模型,用大型有限元分析软件对其进行了额定工况和失效工况下的应力场计算分析,揭示了制动带内部应力场分布规律;同时测量特征点的应力值,试验验证了模型的正确性。
