药湖高架桥车桥耦合振动行车舒适性评价分析

Evlalution and Analysis on Ride Comfort for Viaduct Yao Hu Bridge Based on Vehicle-bridge Vibration

车桥耦合振动是影响行车舒适性的主要因素,为了分析通行车辆的安全和行车的舒适性,对药湖高架桥进行了车桥耦合振动分析。采用模态综合分析方法和Newmark-β数值积分方法分别计算了不同桥面不平度、不同车辆行使速度情况下的车辆响应,结合微型轿车模型,给出了舒适性评价。

Vehicle vibration have certain influence to the driving comfort. In order to analyze the traffic safety and driving comfort,the article analyzes the coupling vibration of the yao hu viaduct. The article calculated vegicle response with different bridge surface roughness and at different speeds combining the method of mode synthesis and Newmark-β modal integral method,and then come up with the evalution of comfort with mini car models.
