Structural design of AGV reducer and its fatigue life analysis

A two-stage reducer structure for AGV is proposed. The finite element simulation analysis of the transmission part of the reducer is carried out by Ansys Workbench, and the stress and strain distribution of the key parts of the reducer is obtained. Adams software was used to conduct dynamic simulation calculation for the virtual prototype to verify the dynamic performance of the whole machine. Based on the load spectrum of finite element simulation analysis, fatigue life simulation of the finite element model of the reducer was carried out by Ncode DesignLife fatigue analysis software, and life cloud and damage cloud map of key components were obtained. The results show that the life prediction of the AGV reducer meets the requirements of the design index, and provides ideas for the optimization design and acceleration life design of the reducer.
