The Fatigue Behaviour of Asphaltic Concrete Made With Waste Shredded Tire Rubber Modified Bitumen
Fatigue Asphaltic concrete Modified bitumen
2009/10/13
Pavement failure can be manifested by excessive cracking due to fatigue. Highway pavements are subjected to a repeated passage of wheel loading of varying magnitude and intensity. Fatigue has been def...

基于修正Craig-Bampton方法的轮胎动态子结构模型（Dynamic Substructure Tire Model Based on Modified Craig-Bampton Method）
轮胎 整车动力学模型 有限元法
2009/9/25
以轮胎模态试验获取的模态参数和参数化轮胎有限元模型为基础，通过优化方法使有限元模型的计算模态参数与试验模态参数一致，获得动力学等效的轮胎模型，将该模型视作连接车辆与地面的子结构，基于修正的Craig-Bampton方法和轮胎接地界面特性，得到轮胎子结构的主模态集和约束模态集，使用模态综合方法实现轮胎子结构模型与车辆多体动力学模型的耦合，此模型可广泛应用于车辆平顺性仿真和整车动态优化设计。
