Abstract:Toimprove the eficiency andautomation level of grain storage operations,research is conducted on the driving andnavigation performanceof grainsilorobotsunderactualworking conditions.This research utilized theDiscreteElement Method(EDEM)for the precise simulation of themechanical propertiesof corn particles.Concurently,by integrating multi-body dynamics software (ADAMS)to develop a dynamic model of a grain silo robot,a coupled model encompassing the interaction betwen therobot andcorn particles was established.The driving performanceof the grain silorobot was analyzed under diferent spiral speeds and body mases;Designed arobot navigationsystem to achieve environmental perception,2D LiDAR mapping,andautonomous navigation functions,andcompletednavigationperformance experiments.Theresults showthatas the spiral speed increases,the robot's travel speed increases linearlywith the spiral speed,andthesliprateand pitchanglealsoincreaseaccordingly,whilethesinkage decreases,theparticlecontactforce increases,andtherobotsdrivingstabilitydeteriorates.Inadition,thesliprate,sinkage,andpitchanglearepositively corelatedwith body mass,whilethe driving speed islinearly negatively correlated with body mass.For every 5kg (204号 increase in body mass,the driving speed decreases by 0.023m/s ,and the slip rate increases by 11.2% .Finally,the grain silo robot can complete multi-point navigation operations with a maximum positioning error of 0.17m ,meeting the needs of use.It provides an important basis for the optimization design of automated equipment for grain silos.
