The Investigation of Ground Traffic Vibration Source Characteristics of Beijing Zhengyang Men Area Based on Traffic Investigation

Zhengyang Men which is located on the north-south axis line of Beijing, is surrounded by the vital communication lines, and suffered from the environmental vibration induced by the busy ground traffic. In order to study the dynamic response of Zhengyang Men city gate and arrow tower, which is caused by ground traffic, the vibration characteristic of ground traffic is the basic research content. The motion equation, which is established by means of the vehicle dynamic model, and the ground traffic characteristic, which is summarized based on the traffic site investigation, are used to derive the vibration source form of a single type vehicle, further more the form of different type vehicle. And then the vibration source can be used for studying the dynamic response of city gate and arrow tower.
