简介：受到动人的负担的一座带子浮桥桥的一个数学模型用简单地支持的横梁的理论被提出。动人的负担模型的二种类型被使用，第一个一moving-constant-force模型和第二个一动人团的模型。用负担的两种类型，当使遭到了到单个移动负担然后多重移动负担时，一座带子浮桥桥的动态行为被模仿。当模特儿在MATLAB软件用完了Simulink包裹。结果显示模型是正确的。当负担在桥上移动了时，动人的负担模型的二种类型对反应范围有小差别，但是对反应阶段有某差别。当负担离开了时，moving-constant-force模型负担导致的动态回答的振幅比动人团的模型导致的那些大。有很多更多的差别当有更多的负担时。
