车身结构
摘要：
本发明公开一种车身结构。一种组装车身组件的方法包括将第一组件定位在第二组件上。第一组件具有不同于第二组件的热膨胀系数，第一组件和第二组件中的一者限定槽。所述方法还包括松动地安装螺栓穿过槽以及第一组件和第二组件，并在第一组件和第二组件中构建接头。所述方法还包括加热第一组件和第二组件，这导致第一组件被第二组件由于响应于加热产生的热膨胀而相对于彼此移动。这样的移动导致接头失效。所述方法还包括拧紧螺栓。
摘要（英）：

A vehicle body structure is disclosed. A method of assembling vehicle-body components includes positioning a first component on a second component. The first component has a coefficient of thermal expansion different from the coefficient of thermal expansion of the second component and one of the first and second components defines a slot. The method also includes loosely installing a bolt though the slot and the first and second components, and creating a joint in the first and second components. The method further includes heating the first and second components, thus causing the first and second components to move relative to each other due to thermal expansion in response to the heating. This movement causes the joint to fail. The method also includes tightening the bolt.
