摘　　要：为研究自动扶梯梯级碰撞失效原因及由于碰撞可能引起的梯级失效模式及危害程度,对国内典型的梯级样品进行结构分析。以铝合金材料为基础,通过对梯级装配体的三维模型和梯级的力学有限元分析,计算梯级的应力和挠度位移形变,得出梯级的屈服强度最大静应力和最大位移挠度断口可能发生的位置。为制定相应的保养和安全管理规范提供理论依据。In order to study the causes of escalator step collision failure and the failure mode and damage degree possibly caused by the collision,structure analysis on typical domestic cascade specimen is carried out.Based on aluminum alloy material,and with the finite element analysis on the three-dimensional model of cascade assembly and cascade mechanics,the stress and deflection displacement deformation of cascade and the possible fracture locations of the maximum yield strength static stress are calculated,and maximum displacement deflection of the step is abtained,which provides theoretical basis for the formulation of corresponding maintenance and safety management specifications.
