摘要
利用ANSYS建立典型的半刚性路面结构的三维有限元模型,并比较动载与静载下力学响应的不同,结果表明动载下的响应偏小。另外,通过改变命令流参数,计算不同速度下的响应结果,发现车速较高时,路面的力学响应反而偏小。
ANSYS is used to establish a three-dimensional finite element model of typical semirigid structure of the surface, and the mechanical response of static load and dynamic load are compared. The results show that dynamic response is small. Then by changing the parameters of the order flow, response to different speed is calculated so that the higher the speed is, the smaller the mechanical response of pavement is.
