| 摘 要： | 基于车辆动力响应的功率谱密度分析,运用自编的车桥耦合振动程序,采用1/3倍频程评价法对过桥车辆的行驶舒适性进行了评价.结果表明,随机桥面不平度是影响斜拉桥行车舒适性的主要因素,应通过有效管理维护使桥面不平度等级维持在"一般"以上;车速对行车舒适性有一定影响,但不明显.所给出的分析步骤和方法可为同类桥梁的相关评价分析提供参考.

| Abstract: | On the base of PSD analysis of vehicle dynamic response,with the self-compiling vehicle-bridge coupling vibration analysis program,vehicle riding comfort is studied by 1/3 time frequency path evaluation method.Analysis results show that random bridge deck roughness is a domain effect factor for ridding comfort of driving vehicle.Keeping deck roughness on average level or better by implementing scientific maintenance is requisite.The influence of driving speed on vehicle comfort is not obvious.The research m... |
