摘要
为分析船桥碰撞动力分析简化模型的精度,以具体桥梁工程实例为背景,分别采用数值模拟分析方法和简化动力分析方法进行船桥碰撞动力反应计算,并定义3种数学指标评价简化模型动力分析结果的精度.实例计算结果表明,动力分析简化模型具有良好的工程计算精度.
To analyze the precision of simplified dynamic analysis method of ship-bridge collision,according to specific examples of bridge engineering,the dynamic response of ship-bridge collision is calculated separately by numerical simulation method and simplified dynamic analysis method.Three mathematical indices are defined to evaluate the precision of the dynamic analysis results obtained by the simplified model.The results of the examples indicate that the simplified model performs good calculation precision in engineering application.
