It seems a farm boy accidentally overturned his wagonload of corn. The farmer who lived nearby heard the noise.
有个农村半大小子像是没留神把一推车玉米给弄翻了，住附近的一村民听见了动静。

But these joined methods can not satisfy the requirement of the heavy loadwagon because of the shortcoming and self limit, therefore needs adopt the new way of joining.
但是这些连接方法由于自身的缺点和局限性，不能满足重载货车的要求，因此需要采用新型的连接方式。

Based on nonlinear FE software MARC, numerical simulation of BOM fastener mechanics in heavy loadwagon is studied. The key technology in constructing the finite element model is discussed.
