分布式驱动电动汽车的胎路接触应力分析
Tire Contact Stress Analysis of Distributed Drive Electric Vehicle
摘要
Abstract
To investigate the mechanical response of asphalt pavements under the distributed drive electric vehicles,a full vehicle-pavement finite element coupling model incorporating the vehicles,tires,hub motors,and pavement structure was established.The Yeoh rubber model and generalized Maxwell viscoelastic model were introduced to characterize the materials properties of tires and asphalt pavements,respectively.The model was validated through tire radial stiffness tests and asphalt mixture loading tests and the error between simulation and measured results was within 10％,demonstrating high reliability of the model.Furtherly,the influence laws of hub motor mass and verti-cal electromagnetic force on tire-pavement contact stress were quantitatively analyzed.The results show that when the vehicle speed is 60 km/h,the vertical,lateral,and longitudinal contact stresses increase by 23.8％,7.9％,and 12.5％,respectively.The research indicates that the additional load effect of the distributed drive electric vehicles on pavements during operation cannot be ignored.The research results can provide theoretical support for the structural optimization of distributed drive electric vehicles and the design of asphalt pavements.关键词
