The different methods for establishing the equations of vehicle-bridge system are summarized and assessed. The vehicle-bridge coupling relationship, including the geometrical compatibility condition and the static equilibrium condition at the interface of wheel/rail, is established. The forces on the vehicles, which coming from bridge deflection and track irregularity, and those on the bridge, which coming from vehicle deflection, are given. Then, the governing equations of vehicle-bridge system are setup.

Given two bridge-builders, a man and a woman, given a certain bridge to be built, and given as always the unchangeable laws of mechanics in accordance with which this special bridge and all other bridges must be built, it is simply inconceivable that the preliminary instruction given to the two bridge-builders should differ in quantity, quality, or method of presentation because while the bridge is building one will wear knickerbockers and the other a rainy-day skirt.

假定分别有男女两位桥梁建造者，要去建造指定的一座桥，在建造这一独特的桥及其它一般的桥的力学规律总是不变的情况下，简直不可想象，男女建造者所受的基本教育应有所不同；更不可想象，只是因为在施工时，一个穿灯笼裤，另一个穿防雨裙，而必须让他们在质量、数量及教学方法上接受不同的教育。

I make "419 roads " going to , passing round north tetracylie sees the "Beijing National Stadium" time be probably 17:40 since traffic control , possessions run by all passing round of the "Beijing National Stadium" north bus,this moment the tetranuclear people of north is not many ,"the intelligent bridge circles in the air from safety" to "strengthening neither having many person bridge " inside, because of but the personnel has controlled face to face ,"the intelligent bridge circles in the air to "strengthening only when the people who holds a ticket can enter secondary safety" bridge " area, Entering mansion , our thereby having stood for one in a nearest fault street overline bridge will be, what all fails to see basically.

还是决定去鸟巢附近看看，由于交通管制，所有走鸟巢北边的公交全绕行，我做419过去的，绕行北四环看到鸟巢大概是17：40，这时候北四环人还不是很多，从安慧桥到健翔桥里面也没什么人，但是对人员也管制了，只有持证的人可以进入安慧桥到健翔桥区域从而进入场馆，我在最近的一个天桥站了一会，基本什么都看不到
