摘要
运用自编的车桥耦合程序,计算(竖向、横向以及纵向)3个方向的加速度,同时以ISO2631的行车振动舒适度为评价标准,选用泸州市某特大桥为工程背景,评价其在不同桥面平整度以及车速下的行车舒适性,并且以良好行车舒适性加速度为界限,对车辆过桥在不同桥面平整度下的速度进行分类,为车辆过桥的速度提供一定的理论依据。
The self-axle coupling procedures are compiled to calculate the acceleration from three directions（vertical, horizontal and vertical）. By ISO2631 vehicle vibration comfort evaluation standards, the bridge of Luzhou is used as the engineering background, the flatness under different bridge decks and the speed of the driving comfort are evaluated. Considering driving comfortsness when acceleration as standards, the speed of the vehicle bridge under different of roughness pavement is classified. This work can provide certain theoretied basis for the speed of the vehicle across the bridge.
