| 摘 要： | 尝试建立有限多个人留驻的简支梁即人-梁联合系统的新动力学模型；然后应用该动力学模型，分析1到5个人形成的人群-简支梁联合系统的动态特性，研究人群对被占简支梁动态特性的影响；并将数值模拟计算结果和国外学者的实验结果相比较，进一步验证所建立的人群-简支梁相互作用的新动力学模型的正确性和合理性，可充分有效地展现人和细长结构的相互动力作用。

| Abstract: | A completely new dynamic model for human occupants-simply supported beam coupled system with arbitrary finite degrees of freedom is established.With the new model,the aurthors investigate the influence of different crowds consisting of 1 to 5 independent human occupants on dynamic characteristics of a slender simply supported beam in detail.Compared with the latest experimental results made by a British scholar,the results of numerical simulation with this new complicated dynamic model show that the built model is correct and reasonable,and it can fully and effectively reflect the dynamic interaction between human occupants and slender structure. |
