Design Of Outdoor AGV With New Type Suspension System And Research On Its Key Technology

Since the 21st century,high precision technology has been moving forward with the development of the times.Automated guided vehicles(AGV)are playing a pivotal role in different fields.AGV have shown their unique advantages in industrial automation,the two most notable of which are a significant reduction in cost and a substantial increase in production efficiency.However,the process environment of many factories that need industrial transformation and upgrading is not confined to indoor areas.Many of the handling tasks need to be carried out between plants,and the outdoor road surface is often not only driving AGV,but also need to drive other vehicles.The road surface is complex and has a lot of potholes.In these ground environments,the driving accuracy and failure rate of traditional AGV are difficult to meet the standards.There is an urgent need to design an outdoor type AGV with high passing performance and low failure rate to fill the gap.This topic mainly relies on the actual outdoor use conditions,and the technical requirements of AGV are proposed for the complex outdoor road conditions,and the key technical excavation of the automatic traction trolley is carried out by using the requirements needed in technology.Before conducting this study,the paper first investigated the current domestic and foreign manufacturers of automatic traction trolleys,conducted in-depth research in the core technology areas and basic work,and proposed the performance characteristics of AGV trolleys based on the hypothetical use environment,and carried out the overall AGV design with these characteristics.In order to adapt to the complex outdoor road conditions,a new type of chassis drive structure is designed,which adopts independent suspension and flexible connection with the main body of the AGV,that is,to ensure the effect of shock absorption and effectively avoid the phenomenon of drive wheel slippage,so that the AGV can ensure the required driving accuracy even in the rugged outdoor road.Firstly,the 3D model of the AGV was designed by using Solid works 3D software.In the design stage,Ansys software was used to simulate the structure of the whole vehicle,and the topology of the designed mechanism was optimized based on the analysis results.The frame structure was optimized by fatigue analysis.Finally,ADAMS software was used to simulate the cross barrier capability,and the final experimental results met the required performance requirements.
