基于应力分布的轮地相互作用纵滑模型
Tire-Deformable Terrain Interaction Model for Longitudinal Slip Based on Stress Distribution
摘要
Abstract
Stress distribution at the tire-ground contact interface on soft terrain becomes increasingly complex under the influence of tire slip and sinkage,making it difficult to accurately model tire behavior.Using finite element analysis,the paper simulated tire longitudinal slip/skid under constant sinkage conditions.The variation in stress distribution at the tire-ground contact interface was investigated as the slip/skid degree changed.The results show three distinct stress distribution patterns corresponding to slip,small skid and large skid states,respectively.Soil characteristic parameters were obtained through simulating sinkage and shear tests,and the stress distribution model was established for the three slip/skid states.On this basis,the tire-deformable terrain interaction model for longitudinal slip was further developed,which effectively represents the in-plane characteristics of tires on soft terrain.关键词
