Abstract：Inorder tominimize thedegreeofdamage suferedbyvehiclesinunavoidablecollsionscenariosand improve roadtrafficsafety，avehiclecollsiondamageprediction modelbasedonthecollsionsimulationdatasetandtherandomforest algorithmisproposed.Thefiniteelementmodelofvehiclecolionsimulationisestablished，andthevehicledamagedataset under16Osetsofwokingcondiionsisobaindbyangingtheollier，collisonangle，collisonoffet，collisonsdetc. This datasetisused toestablishanavehiclecolision damage prediction model basedontherandom forest algorithm，nd the damagepredictionforautomobilecollisionsisprformed.Themultipletestingresultsshowthatthecollsiondamageprediction modelhas an averageabsolute percentage errorof20.09%androot meansquareerorof 3394.Incomparison withthe support vectormachinepredictionmodel，therandomforestcollsiondamagepredictionmodelhasbeterfitingeffect，andthedegreeof dispersion between the predictedandreal values islower，whichcan more acuratelypredict the specificdamagevaluesof the keypointsofthevehicleafteracollsion.Itcanprovideamoredetailedandaccuratereferenceforintelligentdrivingvehicle trajectory planning systems and adaptive constraints，so as to improve road safety.
