I once had a friend called Grunwalski. We were sent to Siberia together. When you go to a Siberian work camp, you travel in a cattle car. You roll across icy steppes for days, without seeing a soul. You huddle to keep warm. But it's hard to relieve yourself, to take a shit, you can't do it on the train, and the only time the train stops is to take on water for the locomotive. But Grunwalski was shy, even when we bathed together, he got upset. I used to kid him about it. So, the train stops and everyone jumps out to shit on the tracks. I teased Grunwalski so much, that he went off on his own. The train starts moving, so everyone jumps on, but it waits for nobody. Grunwalski had a problem: he'd gone behind a bush, and was still shitting. So I see him come out from behind the bush, holding up his pants with his hands. He tries to catch up. I hold out my hand, but each time he reaches for it he lets go of his pants and they drop to his ankles. He pulls them up, starts running again, but they fall back down, when he reaches for me.

我曾经有个叫Grunwalski的朋友我们一起被派去西伯利亚，当你去西伯利亚的一个工作营地，你必须乘坐一辆牲口车，你整天穿行在冷冰冰的西伯利亚大草原上，连个鬼都看不见你为了取暖缩成一团这几乎不能让你感到好受些，你不能在火车上方便，唯一的机会是在火车停下来为机车加水的时候才可以可是Grunwalski很害羞，甚至是我们在一起洗澡的时候，他都有些尴尬我过去经常嘲笑他于是，当火车停下来每个人都跳出去在铁轨上方便的时候我狠狠地挖苦Grunwalski，他走开了一个人在那儿火车开动了，每个人都跳上了火车，它不会等人的Grunwalski遇到了麻烦：他已经去了丛林后面，而且还在方便所以我看见他从丛林里出来，用他的双手提着裤子他想赶上火车我伸出手，可是每一次他够到我的手时他的裤子就要掉下来一直掉到他的膝盖上他提起了裤子，重新追上来，但是当他抓住我的时候，裤子又掉了下来

According to structural characteristics of floating slab tracks, a track segment element was taken between two adjacent fasteners. For each element, rails were regarded as Euler beams supported by discrete viscoelastic supports. The fasteners and rubber supports were replaced by a linear spring and damp. So the vibration model of the floating slab track was established. In constructing vibration model of a metro train, each car of the metro train with two suspensions was modeled as a multi-rigid body system, in which rigid bodies were connected with each other by a linear spring and damp. Combining the potential energy of vertical vibration of the track with that of the metro train, the total potential energy of vertical vibration of the train and track was obtained. And then, the matrix equation of vertical vibration of the system was established using the principle of total potential energy with stationary value in elastic system dynamics and the "set-in-right-position" rule for formulating system matrices. The vibration responses of the system can be obtained by solving the matrix equation with the direct time integration such as Wilson-θ method.
