为了提出适合于评价大跨桥梁行车振动舒适度的标准,对某大跨斜拉桥的行车振动进行现场实测,分析车辆驾驶员座椅处的振动特性以及不同车速下的车内振动加速度有效值;并以国际上通用的ISO2631标准为基础,结合车内人体的舒适感觉,提出行车振动舒适度评价标准,并对该桥的舒适性进行评价。
In order to propose a suitable standard for evaluating the vibration comfort of long-span bridges, the on-site measurement of driving vibration of a long-span cable-stayed bridge was carried out to analyze the vibration characteristics of vehicle driver’s seat and the effective values of vehicle vibration acceleration under different vehicle speeds Based on the ISO2631 standard which is internationally accepted, combined with the comfortable feeling of the human body in the vehicle, the evaluation standard for the comfort of driving vibration is proposed and the comfort of the bridge is evaluated.
